July 2007
Synoptic report
Low pressure enveloped UK during the first four days, the
centre (around 990) moving from N Ireland to just west of
Hebrides. Its warm/cold fronts cleared England early on 1st
and the occlusion crossed the far north overnight, but
showers became heavy and thundery in most areas,
particularly eastern England. The low filled on 4th but a
trough brought more showers to all areas, clearing
eastwards to give a fine night under a passing ridge. By
early 5th rain was already approaching Cornwall as a
deepening frontal wave headed ENE across mid-Atlantic.
The low (995) crossed Ireland later in the day and N
England overnight. Rain soon cleared all areas ahead of
strong W’lies and a few showers. Winds eased on 7th in the
south but a trough crossed Ireland during the morning of 8th
and England/Wales in the afternoon, brining more showers
and thunderstorms. At this time, pressure was high over
Spitzbergen/Greenland and lowest near the Baltic and this
had led to a slow-moving frontal zone lying close to
Shetland. This front moved slowly south into N Scotland on
7th/8th. A small low (1004) formed on the front and moved
south across Western Isles on 9th and tracked SE, bringing
rain to Ireland during day and Wales/SW England overnight.
Rain cleared the English Channel mid-morning 10th. UK was
then in a NW’ly flow with a few showers, chiefly over N
Scotland.
With the only high pressure over Greenland and S Europe,
lows now approached UK from the west. A narrow warm
frontal rainband reached Belfast/Newquay by dusk 11th and
crossed Wales/England overnight while the more active cold
front reached Ireland. After a sunny afternoon in the
Midlands the front crossed Wales and much of England
before trailing back along the English Channel to a
developing wave over Sole. The headed NNE, reaching
Cork (1000) by midday 13th, with rain already well across
Wales/N England. The low crossed Belfast/Aberdeen
overnight and the front accelerated clear of N England and
much of Scotland, but the occlusion was left over Shetland
for a while. The cold front barely cleared the English
Channel before another wave moved north, bringing rain
back to much of England/Wales by midday 15th, the low
(1007) by then over Penzance. With the small low continuing
northwards, rain spread to N Ireland/Scotland, while
thunderstorms crossed Dover Strait to affect SE
England/East Anglia in the afternoon/evening. The cold front
finally cleared eastern England around midday 16th, but rain
near the occlusion made slow progress across central and
NW Scotland. The low reached Hebrides but then turned
back into NW Ireland, leaving rain over N Scotland.
Meanwhile another cluster of thunderstorms moved NE
across S England/Midlands on 17th. Although the low filled
to 1017, it moved SE across Ireland on 18th and areas of
showers and storms affected much of UK.
A ridge now built over Faeroes and brought three days of
sunnier weather to N and W Scotland and N Ireland. By
contrast, further heavy rain and thunderstorms developed
over S England/English Channel on 19th as another low
(1010) formed in the SW Approaches. A broad band of
heavy thundery rain moved slowly NE across S England
overnight and morning just ahead of the low 91009) which
reached London midday 20th. The low turned NNE across
East Anglia and rain spread to N England later in the day but
heavy rain persisted for several more hours over the
Midlands/Wales as the band circulated around the centre.
Rain became more showery over England/Wales on 21st
but the weakening band moved into Scotland as the low
approached Aberdeen. By then a larger low was advancing
2
towards the English Channel and its occluding fronts
brought a WNW/ESE rainband into southern counties early
23rd. Thunderstorms crossed Sussex/Kent in the afternoon.
The low moved along the English Channel towards Holland
and a shallow ridge brought a mostly fine day on 24th, but
the next occluding fronts reached Ireland late evening.
By now, low pressure was developing over the northern
Atlantic and this low took a more conventional route across
Rockall towards north Hebrides. The occluding fronts were
driven quickly across UK on 25th. The low (991) passed
Shetland on 26th but a frontal trough gave further rain over
Wales and much of England. The low became slow-moving
over Norway and showery W’lies spread across Scotland,
veering NW on 28th. However, southern UK remained in the
path of more fronts, with a shallow warm front wave crossing
S Ireland later on 28th and S England overnight. The front
lingered over Cornwall/Channel isles until next morning, but
by then the first mid-Atlantic high of the month was
approaching Ireland. The centre (1025) crossed S Ireland on
30th and the English Channel on 31st, brining sunny
weather to much of UK, but a low near Iceland drove
warm/cold fronts across NW Scotland on 31st.

Weather diary
Note: figures in parentheses give an indication, from first
reports, of the spread of daily maximum and minimum
temperatures,
daytime
minimum
temperatures
(occasionally), rainfall and sunshine in the 24 hours ending
2100GMT. These extreme values are based upon data
provided by the Met Office for the United Kingdom.
Low pressure over W areas of the British Isles led to an
unsettled day on the 1st. It was a generally cloudy day in
most areas with several bands of rain affecting most places
from time to time. Away from these bands, there were some
heavy showers - these merged into further organised bands,
and also turned thundery during the afternoon and early
evening from N England to SE Scotland. By 2400GMT the
low centres were located over the Isle of Man (993mb) and
just N of the Outer Hebrides (993mb). (Weybourne 21.8C,
Aviemore 7.6C, Okehampton 32.8mm, Shepshed 7.6h.)
Met Office surface analysis, 0000GMT 2 July 2007.
The low pressure centre deepened to the W of Scotland on
the 2nd and was slow-moving, giving another rather cloudy
and unsettled day everywhere. There was fog around the
Northern Isles during the morning but rain and showers
tended to be the main feature of the day's weather. Rain was
heavy over NW Scotland early in the morning while
elsewhere the showers turned heavy during the afternoon,
disrupting play at Wimbledon. Showers turned thundery
during the afternoon and evening over parts of NE Ireland, N
July 2007
England, the NE Midlands and East Anglia. (Shepshed
21.9C, Port Ellen 9.0C, St. Angelo 29.4mm, Durham 5.0h.)
The low pressure centre extended E across Scotland during
the 3rd. There was some heavy rain in Yorkshire around
dawn with showers elsewhere across the British Isles.
Thunderstorms occurred in parts of NE Scotland in the
morning, with sferics being reported at this time over NE
England; during the afternoon and evening thunderstorms
became widespread SE of a line Hull-Exeter. The Channel
Island saw some heavy rain before dawn as a shallow low
pushed NE over N France. Parts of south London were hit
by flash floods following a massive storm that swept across
SE England. The storm broke out at about 1600GMT in this
part of London and lasted about 20 minutes. Eyewitnesses
reported seeing the sky suddenly turn dark before the
torrential downpour of rain and hailstones began.
Emergency services were inundated with calls after several
areas including South Wimbledon, Putney, Clapham and
Brixton were hit. The hailstones "were really large pieces of
hail the size of 20 pence pieces which tore through the sky,
ripping leaves from the trees and flowers from plants. I have
never seen anything like it." Minster, on the Isle of Sheppey,
had cars and properties damaged by the sudden deluge.
Parts of the A12 in Suffolk were left submerged by flash
flooding; leaving rush hour traffic grid-locked, while four
people were injured by lightning strikes. (Strathallan 21.0C,
Loch Glascarnoch 5.7C, Stonyhurst 39.0mm, Stornoway
13.0h.)
A cyclonic circulation continued to give unsettled weather
over the British Isles on the 4th. After another cloudy night
an area of rain pushed E across Ireland during the morning to be followed by showers in the W. There were also
showers over Britain in the morning and these continued into
the afternoon. The rain over E Ireland weakened in intensity
as it reached Wales - but as the low centre moved E some
sferics were reported across E parts of England and
Scotland in the late afternoon. (Boulmer 21.0C, Loch
Glascarnoch 9.7C, Woodford 31.0mm, Prestwick 7.4h.)
Another deepening area of low pressure pushed E across
Ireland during the 5th, and was located at 995mb over
Cumbria by 2400GMT. Although there was fog around the
Northern Isles overnight, for most places it was dry overnight
- although there were some showers in parts of Cent S
England and SW Scotland. In Ireland there were also a few
showers ahead of an area of frontal rain that reached SW
Ireland before dawn. There were scattered showers for
many areas during the day, and the frontal rain spread
across Ireland during the morning - also affecting Cornwall
and Devon. During the afternoon and evening the rain
spread across England and Wales and into W and S
Scotland. The fog in the Northern Isles cleared during the
early afternoon - while later in the day there were gusts to
50kn around some Irish Sea coasts. (Bridlington 21.1C, Fair
Isle 9.2C, Dundrennan 16.6mm, Leconfield 5.4h.)
The low quickly moved across N England early on the 6th
and a mostly W'ly flow with widespread showers followed
across the British Isles. The showers were widespread over
N Britain and Ireland - becoming organised into bands in
places. Further S it became drier as the day wore on - with
sunny spells and broken cloud, especially in the evening
when a gradual clearance in the cloud developed over
Ireland and much of S and Cent England and Wales. The
Met Office reported some thunderstorms during the day over
the extreme NE of England and parts of Scotland. (Heathrow
20.8C, Lake Vyrnwy 9.6C, Stonyhurst 37.4mm, Camborne
13.4h.)
Frontal cloud during the 7th meant a cloudy day for Scotland
and N parts of England and Ireland, with some rain; the rain
3
was heavy at times over N Scotland. Much of Ireland and S
Britain had a clear night with a dry day following - although
some showers affected East Anglia for a while in the
afternoon. Later in the day the showers died out but the rain
continued across Scotland. However, the next spell of frontal
rain reached SW Ireland shortly before midnight as cloud
cover increased in W Ireland. (Heathrow 22.4C, Preston
Wynne 8.0C, Kirkwall 32.8mm, Yeovilton 14.3h.)
Met Office surface analysis, 0000GMT 7 July 2007.
Rain continued across N Scotland into the 8th and slowly
spread across Ireland before dawn. However, elsewhere
skies were clear until the cloud over Ireland spread E and
showers started to develop over W parts of Britain. The
showers became thundery during the late morning and
afternoon in E Ireland and also across parts of N Wales and
the N Midlands in the afternoon and evening. The Met Office
reported falls of 15-20mm per hour in places in N Wales and
NW England. Showers later broke out over S Wales and SW
England - although the SE corner of England remained
largely dry and sunny. (London 22.2C, Katesbridge 1.7C,
Capel Curig 35.4mm, Boulmer 12.1h.)
Troughs gave some heavy rain in SW England during the
early hours of the 9th and later in the morning rain and
showers fell further E across S England. Thunderstorms
were also reported over the Channel Islands during the
morning. A low centre moved S over W Scotland towards
Liverpool Bay during the day bringing frontal rain S over W
Scotland and Ireland, and then into Wales SW and Cent S
England. Further E thunderstorms formed during the
afternoon E of a line Cleveland to the Isle of Wight. E
Scotland had a mostly dry and sunny day - as did NW and N
areas of Scotland. (London 21.9C, Braemar 2.6C, Chivenor
26.2mm, Dyce 14.7h.)
During the early hours of the 10th the rain in S Ireland, S
Wales and SW England moved E across S England; cloud
spread across N Scotland to give some rain in places there
by dawn. Elsewhere there was broken cloud overnight in W
parts of the British Isles but mostly clear skies in E England
and SE Scotland. Further cloud and rain affected Ireland
during the day and there were showers and rain over N
Scotland and the SW corner of England and Wales,
especially during the morning. The showers across Scotland
moved S through E Scotland and NE England in the
afternoon - and a cool NW'ly airflow became established
during the day. (Bridlington 21.5C, Saughall 3.1C,
Okehampton 19.8mm, Church Fenton 10.4h.)
Light rain and showers affected parts of the East Anglia and
the Northern Isles into the 11th, and by dawn some frontal
rain and drizzle had pushed E into W Ireland. Cloud cover
was broken elsewhere overnight. The rain in N Scotland
spread SE across E Scotland during the morning, but
amounts were mostly small. Successive bands of frontal
cloud and rain spread across Ireland during the day - but
July 2007
made little progress beyond W Scotland, Anglesey and SW
England. After a cloudy start in many places, there were
sunny spells during the day in many parts of Cent and E
England - although most of Scotland remained rather
cloudy, except in the SE. (Lee-on-Solent 22.5C, Spadeadam
8.0C, Cardinham 7.0mm, Hurn 11.7h.)
Warm air behind a warm front pushed E across Wales
before dawn on the 12th and had covered most of England
and S Scotland by midday - later reaching N Scotland by
midnight. This meant a mostly cloudy morning over England,
after a clear start in the E, with rain and drizzle. Scotland
also had a cloudy morning and afternoon with rain from the
front. Further light rain spread across Ireland during the
morning giving a rather cloudy day here, but there were
breaks in the cloud during the afternoon in parts of Cent and
S England, while late in the afternoon the Met Office
reported some thunderstorms in Lincolnshire. (London
24.3C, Braemar 7.3C, Boulmer 7.6mm, Edgbaston 7.5h.)
4
The 15th brought another low tracking N from Biscay to the
Irish Sea and this drew a warm sector N over E Wales and
much of England during the day. As the warm front pushed
N there were intense thunderstorms reported from Kent
around dawn to the N Midlands in the evening. Overnight
there were largely clear skies ahead of this warm front,
except over N Scotland where rain and drizzle failed to clear
until about midday. Many parts of Ireland had a bright day
until the low centre reached S Britain - rain and drizzle then
followed, with Belmullet reporting a thunderstorm during the
evening. Some of the thunderstorms across England were
locally very heavy, with parts of London experiencing 18mm
of rain in 15 minutes, accompanied by large hail. There were
also reports of a tornado touching down in NE England,
close to the A1 near Sedgefield, at about 2030GMT.
(Charlwood 25.7C, Tulloch Bridge 6.1C, Liscombe 22.8mm,
Tiree 13.6h.)
A complex area of low pressure centred over Ireland caused
a thundery day on the 16th. During the night rain moved N
through N England and Northern Ireland into Scotland,
reaching all but the N of Scotland by dawn and giving some
heavy falls in parts of S Scotland. Misty or foggy conditions
followed the rain in many parts of E England. During the day
the rain and drizzle was mostly confined to Scotland and
NW Ireland and was still affecting N Scotland by midnight.
Behind the rain were showers - which were heavy and
thundery across much of Ireland during the afternoon and
from Cornwall to NE England in the afternoon and evening.
At Aldergrove 20mm of rain fell in one hour. (London 24.2C,
Braemar 6.0C, St. Angelo 33.0mm, Valley 10.8h.)
Met Office surface analysis, 0000GMT 13 July 2007.
Low pressure moved E just to the N of Scotland during the
morning of the 13th and another low centre deepened as it
moved NE over Ireland during the afternoon, being located
over SW Scotland (997mb) by 2400GMT. These meant a
rather cloudy day in Scotland with some rain in the N at first.
A warm sector spread N over England and Wales during the
day giving a cloudy day here with some moderately heavy
rain in places. Similar conditions affected Ireland although
the skies did clear from the W here in the evening. There
were some localised floods in parts of Wales and W
England - with warm and humid conditions across much of
England during the afternoon and evening. Temperatures
across England by midnight were 17-19C in many areas.
(Gravesend 24.9C, Eskdalemuir 5.2C, Pembrey Sands
42.8mm, Kinlochewe 7.3h.)
The 14th began with rather cloudy skies and warm air
across E England but as the low moved NE across Scotland
during the morning this cloud and rain moved E to be
followed by showery conditions that pushed E from Ireland.
The low passage brought some heavy rain over Scotland,
with the Met Office reporting a four-hour fall of 21mm at
Inverbervie. Across Ireland some of these showers turned
thundery during the afternoon and showers occurred over
Scotland after the low centred cleared away - but rain and
drizzle continued to affect the Northern Isles through the
evening. There was a general clearance of the cloud in the
evening as the showers died out over much of Ireland,
Wales and England - although some cloud did linger in S
England. (London 23.8C, Dalwhinnie 9.5C, Port Glenone
25.2mm, Valley 11.1h.)
Met Office surface analysis, 0000GMT 17 July 2007.
A low pressure centre remained close to NW Ireland
throughout the 17th. The Northern Isles had rain, heavy at
times, from an associated front but elsewhere there were
widespread and sometimes heavy showers. These turned
thundery in SW England before dawn many parts of Ireland,
Cent and N England, Wales and S Scotland in the afternoon
and evening. Flash flooding was reported in several places,
including Weston-super-Mare, Tenbury Wells and near
Grantown-on-Spey. Four simultaneous funnel clouds were
reported at Manchester Airport during the early afternoon,
and the updraught from a tornado in Gloucestershire was
apparently sufficiently intense to lift a skip over a house,
according to the Met Office. In Tenbury Wells West Mercia
Police advised that all routes south of Teme Bridge in
Tenbury Wells were affected by the flooding with no access
into the town over Teme Bridge. The Stillorgan area of
Dublin suffered thousands of euros worth of damage after
flooding hit; a local stream burst its banks after an
"exceptional" amount of rainfall took it over capacity.
Numerous properties were damaged as a result of the
flooding, which has prompted authorities to look at ways of
improving drainage across the area. (Weybourne 22.5C,
Redesdale Camp 8.0C, Lerwick 22.0mm, Valley 10.5h.)
July 2007
Low pressure persisted across Ireland on the 18th giving
another unsettled day across the British Isles. Showers were
heavy but thunderstorms were mostly limited to parts of N
England, the E Midlands and W Scotland. There were
reports of hail across parts of N Scotland and S Scotland
with 14mm in an hour at Eskdalemuir. Flash flooding was
reported in Filey in North Yorkshire during the afternoon;
houses were flooded after rain left 3ft of water in homes
following a cloudburst at 1245GMT. North Yorkshire Fire and
Rescue Service received about 60 calls from residents and
businesses relating to flooding. At Kirby Misperton in North
Yorkshire a funnel cloud was seen. The Met Office reported
17.6mm of rain in an hour in Kenley. In between the showers
most places had sunny periods although a S'ward moving
front over Scotland meant longer periods of cloud and
precipitation there. (London 24.3C, Tulloch Bridge 5.7C,
Kenley 23.8mm, Aberporth 14.0h.)
Met Office surface analysis, 0000GMT 19 July 2007.
Cyclonic conditions continued over Ireland on the 19th,
although in many parts of the British Isles there were clear
spells overnight. The low gave some overnight rain over
Ireland and S Scotland but as the day developed so did the
thunderstorms. Thunder occurred over SW England and SW
Wales in the morning and then spread to much of Ireland
and many parts of Wales and W and N England by the
evening. Heavy hourly falls reported by the Met Office
included 15.8mm at Chivenor and 22.8mm at Osbournby
(Lincolnshire). Although the showers died down in many
places in the evening, thunderstorms continued from
Hampshire to Shropshire. A 64-year-old map was attempting
to bale water out of his cellar in Alston during the evening
when he suffered head injuries and later died. Alston was
badly hit by flooding with several homes affected by rising
water, which had run off the fells into the town. A train route
between Tyneside and Cumbria closed for a while after
landslips blocked the line between Brampton in Cumbria and
Haltwhistle in Northumberland following heavy rain.
(Gravesend 25.5C, Altnaharra 5.4C, Lough Fea 23.2mm,
Manston 13.8h.)
Met Office surface analysis, 0000GMT 20 July 2007.
5
The 20th dawned with an area of low pressure over SE
England and heavy thundery rain from the S Midlands to
Hampshire. The low then moved N - centred at 1010mb over
the E Midlands by 2400GMT, and the heavy rain moved N
into Yorkshire and the NW Midlands by the end of the day.
However, the thunder was mostly confined to Cent S
England and had largely ended by late morning, although
there were also separate thunderstorms over NW Wales
before dawn. Parts of Devon and Cornwall remained
generally dry, while E Ireland had rain in the afternoon.
There were showers during the day in a N'ly airflow over W
Ireland while Scotland had sunny spells in the N and cloud
in the S. In fact clear skies before dawn in N Scotland
resulted in a ground frost in places. Brize Norton recorded
115mm during the day, and some places received 30-40mm
in a single hour. In Maidenhead 51mm fell in 63 minutes and
98.6mm fell in the 12 hours ending 1300GMT. There was
significant disruption to road and rail transport as rivers burst
their banks, and flash flooding brought chaos from South
Wales to the Thames Valley. Helicopters were sent to
rescue people from homes in Worcestershire. Roads were
badly hit in the Midlands and across southern England, with
flights and trains cancelled or late. In the village of
Sedgeberrow in Worcestershire, nearly 40 people had to be
rescued from their homes after the River Isbourne burst its
banks - some of them were plucked from their homes by
RAF helicopter. Pupils at the Bredon Hill Middle school in
the village of Ashton Under Hill, Worcestershire, had to
spend the last night of the summer term at school due to
surrounding floodwaters. Fire-fighters were called to help
rescue children from Cherry Orchard Primary School in
Worcester after it was flooded by half a foot of water. The
city's roads were badly hit, with police advising drivers to
take care on the only four remaining routes which were
affected by standing water. Earlier, flash flooding hit many
parts of Berkshire, forcing the closure of at least four schools
in Windsor and Maidenhead, where about 30 homes were
flooded and a woman had to be rescued from her car. The
town's main shopping centre was also shut; however floods
in Maidenhead were the result of excessive runoff, not river
water. The Glade music festival near Aldermaston, Reading,
had to be suspended because of severe flooding with cars
reported "floating around" in the car park. In
Gloucestershire, the council has set up emergency rest
centres to shelter people forced out of their homes by
flooding after the "worst conditions the county has seen in
years". Heathrow Airport had to cancel 141 flights because
of severe weather conditions across the country. Luton
Airport was described as "virtually cut off" by floodwaters at
one point. Parts of south London were badly hit, with roads
submerged under 2ft of water in some parts. Three people
trapped in a building cut off by floods in Barry, south Wales,
were rescued by emergency services. The villages of
Syresham and Helmdon in south Northamptonshire were
badly hit, with a junior school evacuated in Helmdon. In
Hereford, the council handed out Wellington boots to help
motorists trying to rescue about 200 vehicles stranded in a
car park. In West Sussex, Worthing Hospital was flooded by
18in of water, with many homes also flooded across the
county. London's Tube network suffered major disruption,
with the Circle line suspended, the District line partially
suspended and several Tube stations closed because of
flooding. Mainline rail services remain badly disrupted, with
services between London and the south coast and South
West, and services in the Midlands particularly badly hit,
with scores of train cancellations leaving thousands of
passengers stranded. In North Yorkshire several villages
were affected by floodwater, including 30 homes evacuated
in Gilling Beck. Severe weather caused havoc across
Hampshire as flooding, small landslides, fallen trees and
abandoned vehicles block the roads, the worst affected
July 2007
areas being in the N of the county. The M4 and M5
motorways in particular were badly affected by floodwater.
(Gravesend 21.5C, Kinbrace 0.5C, Pershore College
135.2mm, Stornoway 14.8h.)
Met Office surface analysis, 0000GMT 21 July 2007.
The rain area continued to push N through N areas of
England and Wales in the early hours of the 21st and by the
afternoon was falling across S and E Scotland. Rain became
persistent across southern and eastern Scotland during the
afternoon giving a wet end to the day at Carnoustie. S
England, Ireland, the Midlands and East Anglia had showers
during the day, with some sferics reported in the late
afternoon evening in SW Ireland and Cent S England.
Thunder stopped the Test Match at Lords for a while. SW
Scotland had a rather cloudy but mostly dry day, while there
were sunny spells from NW Ireland through NW Scotland to
Shetland. Floods continued to affect large areas of the
Midlands, from Herefordshire to Oxfordshire in particular.
(Gravesend 21.4C, Altnaharra 2.6C, Shobdon 28.6mm,
Lerwick 11.4h.)
Overnight into the 22nd there was persistent rain in much of
E Scotland and generally cloud skies elsewhere, except over
parts of N Ireland where clear skies led to some early mist
and fog. There were also overnight fog patches in parts of
Cent S England and rain in parts of Cent S England, Kent
and Sussex. S Wales had some heavy rain during the
morning and showers affected Wales, E Ireland and W
England as a trough pushed N. The rain lingered in E
Scotland throughout the day while in the evening another
frontal rain area approached SW England and S Ireland.
Many parts of S Scotland and N Ireland had a sunny day
before cloud spread N later in the day. SE England and East
Anglia also had a sunny day. As rainwater continued to
move down flooded rivers, warning of further flooding were
issued in areas affected by the recent rains. The Association
of British Insurers (ABI) said the final bill for the damage and
disruption caused by the latest floods could run into
hundreds of millions with an estimated £2 billion being the
cost of settling insurance claims due to the summer floods
so far. (London 21.9C, Katesbridge 4.5C, Charterhall
30.6mm, Prestwick 11.6h.)
On the 23rd a low pressure system moved E along the
English Channel giving further rain S of a line from Cornwall
and S Ireland to Lincolnshire. The rain was heavy over parts
of SW England. Rain affected NE Scotland early in the day,
and persisted over the Northern isles until the late evening
before moving away to the N. As the low moved E a N'ly flow
became established across W parts of the British Isles; N
England and S Scotland had heavy showers during the
afternoon - with thunder here in places. Further rain affected
cent S and SE England in the evening, before clearing skies
6
spread from the W across much of Ireland, SW Scotland,
Wales and W England. The flooding crisis in central and
western England continued as Britain's two biggest rivers,
the Severn and the Thames, threatened to overflow. In
Gloucestershire 43,000 homes were left without power after
a major electricity substation was turned off because of the
rising water. The Environment Agency warned water levels
were expected to exceed those of the devastating floods of
1947. It said water levels on the River Severn and Thames
could reach a "critical" level in some areas. Severe flood
warnings were in place for the Midlands, Oxfordshire and
Bedfordshire. A spokesman for the agency said the River
Severn and the Thames would continue to swell until
Tuesday and that levels on both rivers could increase
beyond those of 60 years ago. Parts of Worcestershire were
under 2m of water and the Army was deployed to help
emergency services provide supplies to people in Uptonupon-Severn. Residents at risk of flooding in Oxford were
told to leave their homes as water levels are expected to
rise. Some homes in Oxford, Abingdon, Kidlington and
Bladon were flooded. Meanwhile the government had not
ruled out more development on flood plains, as it unveiled
plans for three million new homes by 2020. (Glasgow 21.0C,
Eskdalemuir 4.6C, Isle of Scilly 59.6mm, Prestwick 15.1h.)
The 24th dawned cloudy in E and S England as an area of
low pressure cleared the SE of England; there was also
some frontal cloud and rain across Scotland - but elsewhere
early cloud cover was patchy although in the Channel
Islands there was some lingering rain from the low. Clear
skies across Cent England led to some fog patches by dawn
in Yorkshire. Over Scotland the cloud did not break up in
many places until late afternoon; elsewhere much of
England and Wales away from the NE coast of England had
a sunny day. There were some showers in parts of NE
England and S Scotland and some light rain in NE Scotland
for a while. During the afternoon cloud spread E across
Ireland and into W Scotland - with rain in W Ireland by late
afternoon and in W Scotland in the evening. By midnight this
rain had reached W Wales. (Shoeburyness 23.1C, Threave
3.6C, Manston 8.2mm, Camborne 13.4h.)
Cloud spread E across much of the British Isles during the
early hours of the 25th as frontal rain spread E. Parts of
East Anglia had a sunny start to the day - and by midmorning all of Ireland had brightened up, although rain
showers were starting to break out. The main rain areas took
until near midnight to clear SE England but further troughs
resulted in organised banks of showers across many areas
of Ireland and into W Britain. The main rain area also spread
N and much of Scotland had a rather cloudy day, with rain
still falling on Shetland at midnight. During the late afternoon
a few showers turned thundery over NE Ireland and SW
Scotland. (Wattisham 22.0C, Kinbrace 7.2C, Killowen
16.6mm, Aldergrove 6.9h.)
Low pressure moved NE off NW Scotland during the 26th
and drove several troughs and bands of showers across the
British Isles during the day. During the morning one heavy
band of rain crossed Wales and SW England during the
morning and then moved NE'wards giving some heavy rain
in places. Showers were heavy in places, and there were
widespread sferics reported across N and E Ireland, N and
Cent England and parts of E Scotland in the afternoon and
early evening. In parts of S England the showers were
accompanied by gusts to 40kn on the coast. During the
evening there was a clearance of most cloud across Ireland,
Wales, N and Cent England and S Scotland. (Gravesend
21.1C, Dalwhinnie 9.1C, Sennybridge 32.0mm, Kinlochewe
5.9h.)
Skies remained mostly clear in many E areas of Britain into
the 27th although there were a few showers in W parts of
July 2007
Scotland and Ireland and cloud cover increased in W parts
of Wales and England around dawn. Showers occurred in
many areas during the day; they were mostly light except in
parts of N Ireland and W Scotland. An area of rain and
drizzle spread E across Cent S and SE England and the
Channel Islands in the late afternoon and evening.
(Gravesend 22.5C, Kinbrace 6.1C, Shap 12.8mm, Boulmer
11.5h.)
7
continued to occur over Shetland. (Lee-on-Solent 21.6C,
Katesbridge 1.7C, Manston 20.6mm, Valley 12.8h.)

Met Office surface analysis, 0000GMT 28 July 2007.
The 28th dawned with largely clear skies, except across
Scotland where cloud was widespread in the N and W with
some rain. During the morning this cloud and rain
transferred SE and took until the evening to clear in some E
areas. There were showers during the morning over Ireland
and parts of N England - and rather cloudy skies in S
Ireland. Elsewhere the morning was mostly sunny. The
cloud in S Ireland gave rain in SW Ireland by midday and
this pushed E across S Wales, S England and the Midlands
during the afternoon and evening - giving moderately heavy
falls in places around a shallow low centre. By midnight the
rain had reached Kent and East Anglia - but there were
clearing skies in the evening over N Ireland and around the
Scottish Borders. (St. James Park, London 22.9C,
Katesbridge 5.7C, Kinlochewe 14.6mm, Leeming 11.3h.)
Into the 30th skies were mostly clear except across parts of
W Ireland and Scotland. The cloud led to a few showers that
continued throughout the day in N and W Scotland, while a
ground frost was reported in a few sheltered places under
the clear skies. Some light rain also fell later in N Ireland.
Elsewhere, with high pressure close to Ireland during the
day (1026mb near Galway at 1200GMT), there were only
small amounts of cloud and long sunny spells. During the
evening much of the cloud across England, Wales and
Ireland cleared, although Scotland and parts of NE England
remained cloudy. (St James Park 21.0C, Katesbridge 2.9C,
Loch Glascarnoch 4.0mm, Camborne 12.4h.)
Overnight cloud was mostly confined to Scotland into the
31st - elsewhere clear skies led to a touch of ground frost in
a few sheltered spots. During the day frontal cloud pushed E
and later gave rain to W areas of Scotland and Ireland in
particular. Elsewhere, cloud tended to be patchy and it was
a warm day with sunny spells. (London 24.7C, Sennybridge
3.3C, Lusa 19.6mm, Camborne 14.5h.)
Daily station notes
Southwest England
Okehampton: 16th and 31st - The only days when maximum
temperature exceeded 20C.
Newton Abbot: A notable rainfall event occurred on 15th.
Rain turned very heavy between 0500h and 0600h,
falling at an estimated maximum of 50mm/h briefly
around 0525h, 9.6mm falling in the hour.
Midsomer Norton: The warmest day of the month, with
23.7C on the 19th was followed by the coolest
(14.2C maximum) on the 20th.
Met Office surface analysis, 0000GMT 29 July 2007.
The rain cleared E England by late morning on the 29th and
across most of England, Wales and Ireland a sunny day
followed. Scotland was rather cloudy during the day with
showers in places - and some of these showers also
affected N England and N Ireland. A few showers affected E
England and East Anglia and these turned thundery during
the evening in E England. By midnight, when most shower
activity had died down, skies were clear across much of the
British Isles, except in N Scotland - where showers
Yeovil: Severe thunderstorm on afternoon of 3rd; Brimsmore
Gardens were partly flooded) - 4mm fell in about a
minute.
Central Southern and Southeast England
Chippenham: 20th - heavy rain until mid-afternoon, then
showers.
Whaddon: Only two days separated the highest maximum
(23.3C on 18th) and the lowest maximum
temperatures (15.7C on 20th). Likewise only five
days separated the lowest minimum (5.8C on 8th)
and the highest minimum temperatures (15.7C on
13th). On the 31st a sea-breeze front spread
July 2007
northwards from the English Channel to affect
Whaddon at about 1730GMT and thereafter to
Salisbury and beyond. It was marked by a
noticeable, but temporary, increase in a southerly
wind to force 3 or 4 after a day of very light air.
There was a small drop in temperature and rise in
relative humidity but occurring at the time of day
when such changes would be expected it was
difficult to identify other than by a distinct fresh feel
to the air.
Marlborough: The 20th produced a record low diurnal
temperature range of 1.5C, some 0.2C below the
previous record of 1.7C in 2005. The low
barometric pressure of 999.0mb on the 3rd was a
record for July.
Maidenhead W.: The fall of rain on the 20th (spread across
the 19th-20th rainfall days) totalled 98.6mm in 8.5h
and included a fall of 50mm in 60 minutes (the
heaviest hourly fall locally since 1901). The
70.2mm fall on the 19th was the greatest daily fall
since August 1969.
Reading University: The highest daily pressure reading was
the lowest since 1988, as was the highest
maximum temperature.
Bracknell: 20th - The combined rainfall 19th/20th was
68.3mm; nearly all of this fell during 6 hours on the
morning of the 20th.
Sindlesham: The rainfall event on the 19th/20th produced a
significant amount rainfall in a short period, and far
greater than I have ever recorded in the past 25
years (Bracknell/Sindlesham sites), for 2 to 6 hour
periods, which were as follows: 2 hours 47.2mm
commencing 1015h, 3 hours 57.5mm commencing
at 0815h, 4 hours 67.1mm commencing at 0745h
and 6 hours 75.5mm commencing at 0600h.
Significant flooding occurred on the 20th from the
rainfall, with many roads properties flooded locally.
Further flooding took place on the 21st and 22nd as
the river Loddon burst its banks closing the A329
Reading Road at Winnersh, together with extensive
flooding to local properties and businesses. The
local DIY store evacuated staff on a fork lift truck,
as the river rose so quickly.
Wokingham 2: 2nd - A rainfall rate of 123mm/h recorded
during a violent shower at 1526GMT. 20th 63.7mm of rain between 0200GMT and 1200GMT,
with 50.2mm in the four hours to midday. A peak
rain rate of 177mm/h was recorded at 1103GMT.
Local rivers and streams burst their banks, and the
local secondary school had 62 ground floor
classrooms flooded. The extreme rain event
spanned two rainfall days, and the total is third
highest for any two day period since before 1976.
Enborne, Newbury: The nearest floods to us were at
Thatcham and Pangbourne.
Crowthorne 2: Thundery downpours gave 3mm in 5 minutes
about 1325h on 3rd and 9mm in 20 minutes about
1420h on 15th. 20th - 80mm fell between 2220h on
19th and 1120h on 20th, most of it after 0600h.
This was the largest 24-hour fall in my records
(1973) (next largest 65mm on 20-21.9.1980). New
records were also set for 2, 3, 4 and 5 days rainfall
totals.
Stratfield Mortimer: Exceptional rainstorm 19/20th, 81.1mm
in 15 hours from 2130GMT on 19 July. Rainfall
intensities were the highest observed at this site in
8
20-year records for all periods from 30 minutes to
24 hours. The fall was split across two rainfall days
(19 July, 25.8mm: 20 July, 55.3mm) and the
combined two day total (81.1mm) has been
exceeded only once since local daily records began
in 1910, viz. 14-15 September 1968 when 91.0mm
was recorded. On this latter occasion the rainfall,
although very heavy and persistent, was distributed
over a period of 36-48 hours rather than the 15
hours on 19/20 July 2007. It is therefore highly
likely that the rainfall of 81.1mm recorded within a
24-hour period on 19/20 July 2007 represented the
highest 24 hour total in this area within the last 100
years or more. The peak occurred shortly before
1100GMT, when 21.0mm fell in 30 minutes
commencing 1035GMT: 30.2mm fell in the 60
minutes commencing 1005GMT. In the 4 hours
commencing 0730GMT 64.3mm fell. The Foudry
Brook reached its highest level in 20 years
observations, and significant flooding resulted in
Stratfield Mortimer from the failure of a major
culvert at the bottom of The Street during the storm.
There was also extensive floodplain inundation on
the Loddon, the Kennett and the Thames as a
result of the heavy rainfall. During the violent
storms on 20th, global solar radiation averaged
2
only 10-11 W/m 08-11h, falling to just 4 W/m2 at
0834, 0909 and 1030 UTC, less than 1% of normal
insolation levels and below the 'day darkness'
threshold. The month's highest maximum (23.6C on
19th) was lower than April's highest maximum
(24.4C on 15th). This is the first time this has
occurred on local records back to 1917 - the
nearest being in 1939 (April maximum 23.9C, July
25.0C). The highest maximum in July averages 9C
above April's value. The July 2007 maximum was
the lowest for the month since 1988 (22.5C) - only
1988 has had a lower July absolute maximum
within the last 40 years. The maximum of 16.6C on
20th and the minimum of 5.4C on 31st were both
the lowest in July since 2000. Hail fell on 3rd, only
the third July with hail in the last 20 years. There
were five days with thunder heard, the highest for
any month in 5 years (5 in August 2002).
Portsmouth University: The absolute maximum temperature
of 21.9C on 24th was the lowest since 1998, and
only marginally higher than the long-term mean
July daily maximum at this station.
Hurstpierpoint: For the third month running the weather was
unsettled and July was a cool, wet month. The 5th
to 8th saw a break in the unsettled weather with
unbroken sunshine on the 7th and 8th. Unsettled
weather returned on the 9th and lasted until the
28th. Up to the 18th, with 29.6mm, rainfall totals
had not been particularly high for any one day. It
now turned very wet. Between 0530h and 0930h on
the 20th 32.6mm fell but, a little further to the north,
the totals were up to 53mm. This caused serious
flooding in Haywards Heath and East Grinstead.
There was further heavy rain or showers on the
21st and 23rd and some on the 25th. Thus, the
total of 70.3mm from the 19th to 25th inclusive
made it the wettest seven-day period in July since
1951. The 10-day total of 81.6mm from 19th to 28th
was also a new record for July.
Steyning: 15th - frequent thunder to the W and NW 13001400GMT as a thundery area moved NE through
Chichester/Pulborough, West Sussex. 19th 35.3mm fell 0610-0910GMT.
July 2007
Birdham: 15th - A thunderstorm 1120-1250GMT with
torrential downpours led to temporary flooding.
Horsham: Heavy rain spread up from the South in the early
hours. Torrential rain fell from about 0700h with
thunder heard to the south at 0755h. 'Day
darkness' set in for a time. A thunderstorm
accompanied by further torrential rain began at
0902h. Only a few cloud to cloud lightning
discharges were seen accompanied by rumbles of
thunder. The storm cleared by 0845h to the NW but
moderate/heavy rain continued finally clearing by
1030h. Total rainfall up to 0900h/20th was 41.4mm.
Hourly Rainfall amounts - 0600-0700h 2.8mm,
0700-0800h 15.6mm, 0800-0900h 20.2mm, 09001000h 11.0mm.
Hove: 12.5mm of rain in 36 minutes starting 0727GMT/20th.
Morden: 20th - 41.2mm of rain, wettest July day on record
(1988). AWS recorded 35.2mm 0957-1057GMT.
Caterham School: 20th - 34mm of rain fell in 80 minutes.
31st - 6.7C was a very low minimum temperature
for the time of year.
Coulsdon: On the 15th 18.5mm of rain fell in 20 minutes
from 1450h and 14mm transparent disc shaped hail
fell too.
Warlingham: 15th - The maximum temperature of 25.8C
seems to be about the highest in the country that
day, maybe because this station missed the severe
storm a few miles to the W and the sun therefore
shone longer. Very humid with dew points of 18C or
more. Some radiation mist observed at 2200GMT
with a temperature of 18C. 20th - torrential rain in
the morning from about 0830GMT, ceasing around
1100GMT. Some thunder but very little given the
rainfall amount. Very dark; camera exposure
1/15th, f/2, ISO400, about 0.4% of normal daylight.
A few houses in the road were flooded, almost
entirely with run-off from a neighbouring field. This
is very rare; it was the wettest July day on record
(1983).
Bagshot: The 'storm' on the 19th/20th produced 78.3mm
during 0600-1230h. Extensive flooding occurred
during and after the storm, with roads closed due to
flooding and the local rivers and streams bursting
their banks, especially the Bourne and Halebourne,
with the A319/A3046 through Chobham closed for
several days. Properties locally were flooded.
Caterham on the Hill: 20th - Torrential rain led to flooding;
accompanied by thunder and lightning.
Brockham: 20th - Wettest day since 2002, 36.8mm falling in
4 hours (0700-1100GMT), heaviest fall 9mm in 10
minutes around 0930GMT.
Wilmington, Swanley: Torrential rain on 20th caused local
flooding in Swanley and water poured through the
roof of the admin block, a Victorian house, at the
school where I teach.
Bromley, Hayes: Almost all the 25.3mm of rain on the 20th
fell in 40 minutes starting 1030GMT during a severe
thunderstorm.
Northwood: 21.7mm of rain on the 20th gave the wettest
July day since 1992 (33.1mm on the 20th).
Twickenham: The two hottest days on 19th and 20th were at
24.5C and coincided with thunderstorms and heavy
rain. The wettest day saw a fall 47.8mm on 20th.
Total rainfall over the two days was 55.5mm. Our
9
gardens were covered in water and in front of the
house water was over the pavements and drains
were spilling water and sewage (the latter a regular
complaint in Twickenham and Isleworth due to
discharges into the Thames where it can take time
to get clear due to the tidal flow). Teddington was
badly affected as the main street gets the run-off
from higher ground and motorists would not slow
down, forcing water into flooded shop premises.
Local papers later in the week had many incendiary
letters on this and related subjects. There were the
usual flood warnings regarding high water from
Chertsey to Teddington Lock which after the tides
turned, led to warnings down to Putney as the vast
head of water rushed downstream. Fields, gardens
and buildings were flooded to an extent not seen
for some years.
Forest Hill: I was in Brockley (about 2 miles N of my station)
during the afternoon of the 3rd; large and
impressive cumulus cloud had been building and
developing into cumulonimbus, and during 16201640h I was caught in a torrential downpour, the
heavy rain accompanied by hail 7-8mm in diameter;
when I measured the fall in my gauge I was
surprised to note only 2.1mm, showing the huge
difference in fall over a short distance. The other
day of note was 20th when during the heavy rain
1100-1140h the conditions became very dark,
windy and thundery. Surprisingly after such stormy
weather the skies cleared from midday with sunny
periods following.
East Anglia
Royston: 19th - Highest temperature (24.5C) of the month
recorded; this was the lowest absolute maximum
temperature in July since 1988 (22.6C).
Great Gaddesden: Torrential rain on the 20th, particularly
1240-1320h with over 13mm in 10 minutes from
1250h. Leighton Buzzard Road was flooded
opposite my station; there was only occasional
thunder.
Borehamwood: 20th - 22.4mm of rain fell within half an hour
around 1300h.
Watford: On the 20th very heavy rain fell after 1110GMT with
10.8mm in 12 minutes from 1112GMT and 22.8mm
in 36 minutes from the same time.
Rettendon: The monthly maximum temperature of 23.8C on
the 16th is the lowest in July since 23.3C in 1988.
Bramingham, Luton: Total rainfall on 20th (35.9mm) was
highest in July in single rainfall event since at least
1981.
Luton: Estimated fall of 30mm in little more than half an hour
on the 20th.
Ely: Highest maximum temperature of 24.1C lowest in July
since 22.6C in 1988. Highest pressure of 1021mb
was the lowest in any month since September
2001.
Beccles: The 26.5C 'highest maximum temperature' is the
lowest such figure to the end of July in any year
since 1981, when no higher than 26.3C was
recorded - in June that year.
Midland Counties
Charlton, Wantage: torrential rain on 20th gave 103mm, plus
15.6mm previous night, makes 118.6mm for the
July 2007
10
total fall. Records were consequently set for daily
and monthly rainfalls in July (172mm).
Pitsford
Charlbury: The total rainfall of 70.2mm on the 20th is the
second highest amount for a single day in any
month on record (1990). The River Evenlode which
runs along the W edge of Charlbury rose about 6m
by the 21st, totally submerging the road bridge of
the B4437 which suffered significant damage.
Gloucester: Another wet month, which started with falls of
13.3mm and 21.5m measured on the morning of
1st and 2nd, respectively, then no less than
18.7mm was measured on the mornings of 20th
and 73.4mm the following day. The rain started at
0200h/20th and continued for 18 hours, by which
time 83.2mm had fallen into my gauge. From 0915h
to 1845h 60mm fell and at its heaviest rain was
falling at the rate of 5mm in 30 minutes. The rain
fell over a large area and caused floods on the
Avon and Severn rivers which meet at Tewkesbury.
Hall: Some heavy showers were recorded,
particularly on the 1st, 3rd and 5th, and for the
second time within a month the village of Stoke
Goldingston
on
the
county
border
with
Buckinghamshire was flooded. The village saw
some 60mm of rain in the space of 24 hours on the
2nd. 20th - Villages in the south of the county were
hit by flooding, particularly Helmdon, Syresham and
Silverstone.
Bablake: 12th - The warmest day of the month only
managed a maximum temperature of 23.5C - this is
the lowest such value since July 1988 (21.9C). 20th
- The wettest day of the month (38.1mm) became
the wettest July day in Coventry since 1991
(52.5mm). Only four July days have ever been
wetter than this since before 1892 (1922, 1968,
1969, 1991). 31st - A grass minimum reading of
just 2.8C was the lowest such value during any July
since 1993 (1.7C). We haven't had a July ground
frost in Coventry since 1921 (-2.8C). 31st - We had
to wait until the last day of the month to enjoy July's
sunniest day (12.8h); nevertheless, this was the
lowest such value since 2001 (12.6h).
Gloucester: 20th - Rainfall totals reported from AWS sites
around the city include
Longlevens 70mm,
Elmbridge 90mm, Tredworth 101mm and Tuffley
86mm.

July 2007
Temperature
Mean temperatures during July were below average except
for small coastal regions of E England, the Northern Isles,
NW Scotland and NW Ireland. Across much of Cent
England temperatures were as much as 1-2C below
average. Many observers commented that it was the first
month with the average temperature less than the 19712000 mean since March 2006. Daytime maximum
temperatures could never really be described as high, with
the absolute maximum temperature at many stations among
the lowest on record for July. The mean minimum
temperatures across the British Isles were, however, much
closer to the average. At many places the highest and
lowest temperatures of the month occurred during the final
few days of the month with some places, e.g. Crymych
having both temperature extremes on the same day. Some
observers commented upon the act that it was the coldest
July since 1998 or even 1988.

Rainfall
July was a wet month, with only parts of SW Ireland, The
Hebrides and Cumbria being drier than average. In many
areas, particularly E Ireland, Wales and Cent and S England
precipitation amounts were more than twice the average –
and in parts of the SW Midlands over four times the average
rainfall for July was recorded. Much of this excess was due
to very heavy rainfall on the 19th-20th that led to devastating
flooding from Berkshire to the W Midlands while many COL
stations in Wales also reported that the 13th was a very wet
day. Storm totals on the 19th-20th amounted to over 100mm
in under 24 hours in some places. However, the wetness of
the month was not only due to these heavy falls, as many
stations also reported an increased number of rain days,
indicating an increased rainfall frequency compared to
normal. According to the Met Office the month was the
wettest July in the UK since 1988, over England since before
1914 and over Wales since 1939.
SW
SE
S
Provisional data indicate that the May-July period was the
wettest for England and Wales in a series from 1766 with
many areas registering more than twice the long term
average - remarkable for a three-month period. Parts of the
Midlands and Lincolnshire, in particular, received over three
times the average fall for this period. Over England, Wales
and Scotland the rainfall total for the past 12 months
exceeds the normal annual total by over 30% on average.
Sunshine
Sunshine amounts were generally lower-than-average
across the UK, with deficits amounting to about one-third of
average over NE Scotland, but above average in Ireland.
Amounts were as much as 40% above average in parts of W
Ireland. In many parts of England and Wales the total
duration would have been a lot less were it not for sunny
conditions during the final five days of the month – these
were for many places in England and Wales the sunniest
days of the month, the number of days with 10h or more of
sunshine being very low for the time of the year.
Pressure
The mean MSL pressure was generally the lowest for July
since 1988 (and since before 1961 in parts of SE England).
Not until the last three days of the month could the pressure
patterns across the British Isles be described as
anticyclonic. Monthly mean anomalies ranged from 7-8mb
below average over NE England and E Scotland to about
4mb below average in the Channel Islands. Observers
commented upon the fact that the highest pressure for the
month was generally low. Winds were predominantly from a
W or SW direction during the month across the British Isles,
May-July 2007 rainfall as a percentage of the 1971-2000
average.

and changeable, often cyclonic but fine from 29th.
July 2007
Newton Abbot: A rather cloudy, but very wet month with high
mean relative humidity.

at 19.6C, 1998 cooler at 19.2C. Second lowest
maximum temperature for July (22.6C), 1998
lowest at 22.5C. Wettest July on record (1990).
Gurney Slade: Total rainfall for May-July 432.7mm, 180% of
average.
Totterdown, Bristol: July 2007 rainfall for Totterdown was
138.0mm making it the sixth wettest since
continuous records were collated for Bristol starting
in 1882. This is 294% of the 30-year average. The
July 2007 mean temperature for Totterdown was
16.3C making it the coolest since 2002 when the
average was only 15.6C for the month. It was 0.5C
below the average temperature for June this year.
Total average daily solar radiation for July 2007
was 24.7% lower than July 2006.
Central Southern and Southeast England
East Stour: The wettest July in 25-year record with the
lowest absolute maximum temperature since 1998.
The May-July rainfall total is the highest on record
(331.1mm, previously 208.6mm in 2002).
Dorchester: Rain fell on 22 days in July - the most since 25
days in 1936. Mean maximum temperature was the
lowest since 1988. The absolute maximum
temperature was 22.2C - the lowest since 21.0C in
1965.
Bournemouth, West: Lowest July mean pressure since
1988.
Weymouth: The sixth wettest July on record, and the wettest
since 1977.
Thornford: Wettest July since my records began here in
1999.
Blandford St. Mary: The fourth wettest July (124.4mm) on
record (1919), the third wettest was 131.6mm in
1939. The wettest May-July (362.9mm) on record,
the previous being 305.6mm in 1924.
Salisbury: Coolest July since 1988 and the wettest July for at
least 50 years. Total rain for June and July was
224.9mm (the average is 100.4mm). Total rain for
May to July 2007 was 320.6mm (average
148.1mm). Just as remarkable too - a total of 41
rain days out of a possible 46 days from 13 June to
28 July inclusive, with only 2 completely dry days
during this period. Occasionally in autumn or
winter, maybe (or in Wales, N England or
Scotland!) - but in this part of the country, in
summer - completely unheard of!
Whaddon: The three months (May - July) produced
330.4mm of rain. This is insignificant compared to
some places but none-the-less is a remarkable
total for three summer months. Only three of the
last 13 months have produced below average totals
here in southern Wiltshire.
Marlborough: July broke the trend of 14 successive, above
the mean monthly temperatures with 1.1C below
the long-term average. The rainfall of 127.2mm was
a record for the month.
Maidenhead W.: The wettest July since before 1924 and
mean temperatures slightly below average.
Reading University: The mean pressure was the lowest
since 1960 and the mean temperature was the
18
lowest since 2000. Mean soil temperatures at 5cm,
10cm and 20cm were also the lowest since 2000.
Total rainfall was the highest since 1950 and the
second highest since before 1921. The number of
rain and wet days were the highest since 1988 and
1957 respectively. Mean wind speed the highest
since 1991.
Reading (Donnington Gdns): Wettest July since records
began (1989).
Bracknell: Wettest July on record (1991).
Bracknell, Roman Wood: The mean daily maximum was
equal lowest (with 2000) for July since records
began (1989). The highest maximum temperature
(just 22.6C) was the lowest on record.
Wokingham 2: Rankings - Mean maximum 38th lowest,
mean minimum 35th highest, mean temperature
56th lowest, rain total 7th highest, all in the past
126 years. Highest maximum temperature 4.3C
below the median, and tenth lowest in 104 years.
Wettest July since 1957 and before that, 1920.
Highest mean wind speed for July since 1993.
Mean pressure and absolute highest both lowest
since 1988.
Crowthorne 2: Continuation of the June wet spell brought the
20-day total from 15 June to 4 July to 116mm,
exceeding the record (1973) highest 20-day fall in
June-August of 106mm in August 1999. The new
record was then exceeded by 125mm in 15 days
from 15 to 29 July. The July total of 150mm is the
highest of record (1973), next being 108mm in
1988. The record fall for June-August of 230mm in
1997 was exceeded by 26 July. Rainfall so far this
year (540.5mm, 161% of average) is highest of
record (next comes 430mm in 2001). The May-July
total of 357mm is the highest for Crowthorne from
1881, ahead of 321mm in 1903. The June-July total
of 245mm is the highest bar 1903 (251mm). 1903 is
also the only year with more January-July rainfall
(570.5mm); as sheltering is estimated to reduce the
catch of my gauge by about 6%, this suggests
near-equal falls. The temperatures were notable for
the lack of warm days, the highest maximum of
22.0C being the second lowest of record (1973)
after 1988 (21.1C). The monthly range of 13.1C
was also second lowest after 1988 (12.1C).
Stratfield Mortimer: Rainfall 142.4mm, 366% of 1971-2000
normal: on local records extending back to 1862:
only the notoriously wet July of 1875 was wetter
(155.4mm). The last July with over 100mm was 50
years ago (1957, 123mm). Within the last 30 years
the wettest July was 1988, with 88.4mm - not even
two-thirds of July 2007's fall. May-July total 360mm,
248% of the 1971-2000 normal and by far the
wettest such period since local rainfall records
commenced in 1862 - the previous highest being
275mm in 1879. For 2007 to 0900 GMT 1 August
580mm has fallen, 85% of the annual average and
161% of the normal over this period (and this
despite April's fall of just 0.7mm, the driest month
for almost 50 years). Persistently cool - coolest
since 1988. Mean maximum temperature (20.2 C)
2.1C below the 1971-2000 normal, and 7.4C below
the July 2006 mean - last July's lowest maximum
(20.8C) was higher than this year's average. The
first month with a mean temperature more than
1.0C below the 1971-2000 normal since December
2001 (anomaly -1.8C). July was dominated by
south-westerly winds in a manner rarely seen
July 2007
outside the winter months: 496h (67%) of the
month saw winds within just 60 degrees from
200deg. Mean MSL pressure at 0900GMT
1011.8mb, 5.5mb below normal; the only lower
value since 1936 (1010.5mb) has been 1011.4mb
in 1988, although 1011.8mb was equalled in July
1960. The absolute maximum barometric pressure,
1022.4mb, is the lowest for any July since 1980
(1021.5mb) except for 1988, which was 0.1mb
lower.
Portsmouth University: The mean daily maximum and the
mean monthly temperatures are the lowest since
1998, which was marginally colder (by 0.3C), but
much drier. Mean maximum temperatures were
only 1.6C higher than in April 2007, which was a
much sunnier month! It was the wettest July on
record at this site. A clearly dismal summer month
with limited sunshine and a high number of rain
days.
Fleet: The wettest July on record (1967) with 238.0mm in
June-July combined.
Fleet, Ancells Farm: The wettest July since records began in
1997 and the sixth wettest month of any name.
Portchester: Very wet but no exceptional downpours.
Lymington: The wettest July on record (1987), after May and
June also being the wettest on record. The number
of wet days (18) was way above the previous
record (11).
Hurstpierpoint: The coolest July since 2000. However, it was
the first month with the mean temperature below
average since March 2006. My station missed the
heaviest of the rain on the 20th and, with 111.2mm;
it was the second wettest July since 1951 after
1991. On the other hand, it was the wettest second
half of July since 1951. For the May to July period,
it was the wettest since 1951 with 295.3mm (189%
of average).
Steyning: The wettest May-July on record (1923-2007) by
40mm and for June plus July it was the second
wettest by 1mm (previously 1991). The third wettest
July with 131.8mm, beaten by 1960 (137.7mm) and
1957 (137.4mm). The first month with below
average temperature since March 2006.
Birdham: The mean maximum temperature was the equal
fourth lowest since 1975, and it was the third dullest
July since 1981. The wettest July on record (1976).
Horsham: Overall a rather cool and unsettled month with
mean temperatures similar to June. The maximum
air temperature reaching only 25C on the 15th was
the 'lowest' recorded for July since 1998. It was by
far the wettest July on record at this station since
records began in 1983, with 116.4mm. The May to
July rainfall stands at 273.8mm compared with
140.2mm for the same period last year.
Hove: The fourth wettest July in 38-year record after 1987,
1991 and 1992. The number of rain days was the
highest since 1988. The coolest July since 2000.
Morden: Wettest July on record (1988) and the wettest in
area since 1956. Coolest July since 2000. Monthly
maximum temperature (24.5C) is the lowest in July
since 1988.
Epsom Downs 1: Second highest July monthly rainfall at
130.9mm (152.9mm in 1956). Daily rainfall on 20th
at 35.7mm was third highest rainfall for July
(35.8mm in 1992 and 36.5mm in 1997).

Epsom Downs 2: Wettest July locally since 1956. The 20th
was the wettest July day since 41.2mm fell on
31.7.1978.
Coulsdon: Monthly: Wettest July in station record at
119.2mm and the wettest July locally since 1956.
The absolute maximum temperature of 22.6C was
the lowest since 22.2C in 1988. The lowest
maximum temperature of 17.5C is one of highest in
station record (1980).
Warlingham: The second wettest July on record (1983) after
1988.
Guildford, Park Barn: Wettest July (126.1mm) on record
locally (1949), previously 110.2mm in 1956.
East Ewell: Up to 31 July, the year's maximum temperature
here was 25C on 15 April.
Bagshot: The July total of 166.9mm (355%) was the highest
recorded on local records back to 1860, beating the
previous highest of 157mm in 1880. The May to
July 2007 period has recorded 399.1mm beating
the previous highest of 360.4mm in 1903.
Brockham: Coldest July in area since 1988 - all maximum

Wigmore: We had a couple of days with rainfall approaching
25mm but no records were broken here.
Boughton-under-Blean: Wettest July on record (1995).
Edenbridge: The normal monthly rainfall fell in one day 20th. A quite windy month.
Maidstone: A very wet month, but a drier period 6th to 18th
with 13.7mm falling towards the monthly total of
100.2mm. Three wet days, 19th, 23rd and 28th with
13.2mm, 21.6mm and 15.2mm respectively,
although these are insignificant when considering
some of the monthly and daily totals in other parts
of the UK.
Appledore Heath: Over the month, pressure was relatively
low at 1013mb and the highest pressure of 1020mb
was achieved on the last day of July.
Northwood: The coldest July since 2000 and the wettest
since 2002. A maximum temperature of 25C has
not yet been recorded this summer.
Forest Hill: Wettest July on record (1975) beating the
previous wettest of 87.3mm in 1980. The 19 rain
days beat the previous highest of 18 I recorded in
both 1980 and 1988; the 13 wet days was second
highest total after 16 in 1980. Cooler than average
by day but very close to average by night, making
this the coolest July since 2000. More notable was
the fact that the highest temperature during July
failed to reach 25.0C; this was only the second time
this has happened since my records began in 1975,
the other occasion being in 1988 when the monthly
maximum of 22.8C was even lower than the 24.4C
this July.
East Anglia
July 2007
Royston: First month since August 2006 with a below
average mean temperature (but by only 0.4C), thus
ending a remarkable run of 10 consecutive warmer
than average months. The coolest July since 2000;
mean temperature 4.6C below July 2006.
Great Gaddesden: The wettest July on record (1971) and
the lowest absolute maximum temperature since
1988.
Watford: Total rainfall (89.9mm) was the most since 1988
but the total sunshine hours was only 155.4h, the
lowest since 1993. The rainfall for the 3 months
from May to July 305.8mm was the highest in
record (1961) for this period. The total for the 12month period from August 2006 to July 2007 was
958.1mm, exceeded for this period only by 1988/89
in last 46 years.
Galleywood: A cool and unsettled month. No warm days,
with absolute maximum temperature the lowest for
July since my records began in 1987. Coolest July
since 2002 and sixth coolest since 1987. The third
wettest July, behind 1987 and 1988, on record
(1987).
Rettendon: 18 rain days, the most in July since 21 in 1988.
Benfleet: The wettest July since 1987 and the coldest since
1988. The highest temperature so far this year is
24.6C in April.
Southend-on-Sea: A month when it never really settled
down.
Epping: Coolest July since 2000 and wettest since 2001.
Second lowest absolute maximum temperature for
July since records began here in 1979 (July 1988
was the lowest with 22.0C).
Gestingthorpe: We have not yet reached 25C this year.
Bedford: A very W'ly month and the wettest July since 2002.
We have missed the worst of the rains but the MayJuly total of 274.6mm is still the most on record.
Bramingham, Luton: The 23.3C maximum temperature for
month was the lowest such value since at least
1992. July was the only summer month (June to
August) since 1992 to have an absolute maximum
temperature below 25C. The mean maximum was
7.3C below that of July 2006. It was the wettest July
since at least 1997.
Luton: Absolute maximum temperature of 23.9C was the
lowest in July since 1988. Greatest number of rain
days and wet days in July also since 1988.
Clifton: The lowest July mean temperature since 2000, but
the highest temperature of the month of 24.6C was
the lowest since at least 2000.
Thurleigh: At the time of writing, 3 August, I have yet to
record a temperature of 25C or above this year. My
highest to date in 2007 is 24.9C, once in May on
the 24th and once in June on the 2nd.
Ely: Coldest July since 2000. Mean maximum temperature
6.6C below same month last year. Total rainfall for
last 3 months is 267.5mm, 183% of normal.
Beccles: The rainfall of May-July (392.3mm) is the most for
any three consecutive months on record - nearly
60% of the annual average. By the end of July the
rainfall for 2007 is about 92% of the annual
average. The sunshine total was 212.3h (97% of
average); the shortfall would have been significant
but for 61.3h in the last five days.
20
Chedburgh: Coolest July since 2000. Wettest May-July
combined (265mm) on record (back to 1946).
Old Costessey: A dull, wet, and thundery month. Some
nearby roads impassable for several days due to
flooding.
Calthorpe: Coldest July since 2004 and the wettest only
since 2005.
Buxton: July came out exactly on the 30 year average for
both maximum and minimum temperatures. This
means that it is now 12 months since we had a
month with below average temperatures. Despite
April having no rain we now have had 97% of our
normal annual rainfall.
Midland Counties
Henley-on-Thames: The wettest July on record (1966) and
also the wettest June-July combined and May-July
combined.
Charlbury: Both the mean and mean maximum temperatures
were the lowest on record (1990) and it was the
wettest month of many name in the same period.
Gloucester: Another extraordinarily wet month as the figures
show.
Desborough: The coolest July since 1980.
Bablake: What a difference a year makes! Twelve months
ago, we were celebrating July 2006 (20.5C) as the
hottest month at any time of year in Coventry's 114
years of weather records; by contrast, July 2007
(15.7C) has been the coolest in the city since 1988!
Only two July months have been cooler than July
2007 in the past 30 years (1980 and 1988). The
average monthly temperature of 15.7C exactly
matches that of June this year - this is the first time
that July has not been warmer than June in
Coventry since 1970. July 2007 has become the
first month with mean temperatures below the 30year climatological normal for the city since March
2006. With 139.7mm of rain (almost three times the
city's average), this has been the wettest July in our
region since 1936 (141.6mm). Only six July months
have been wetter than July 2007 since monthly
rainfall data became available in 1870 (1875, 1880,
1888, 1915, 1922 and 1936). July 2007 became the
third month in succession in Coventry to record
more than 100mm of rain - this is the first time this
has occurred since November 1876 to January
1877. Although we enjoyed the driest April in the
city since 1938, the first seven months of 2007
have recorded 659.4mm of rain, making this the
most rain recorded in this period since before 1870.
The previous highest January to July monthly total
was in 1872 (589.7mm). As a note of interest, this
year's total is more than double that of the same
period last year.
Tenbury Wells: Wettest July on record (26 years) and the
wettest month of any name during this period.
May-July 2007 was the wettest 3-month period
recorded here - 482.6mm (347% of average) nearly 90mm more than the previous wettest
(October-December 2000).
The period included
five of the fifteen individual wettest days on record,
including the two highest 24-hour rainfalls. During
the 14-day period 13-26 July, 170mm of rain fell.
Bromyard: The coolest July since 1988 and the wettest
month on record (1980).
July 2007
Malvern Link: The wettest July on record (1889) largely due
to the exceptional fall on the 20th. Totals around
Malvern ranged from 186mm to 214mm, the
previous record being 148mm in 1915. The coldest
July since 1988.
Tipton: Unsettled and the wettest July ever (1995). Second
only to 1988 as the coolest July ever (1985).
Dudley: The first month for over a year with below average
temperatures. Second wettest July since 1968
which had 150mm. Second wettest July day on
record, wettest was a fall of 68mm on 17.7.2001.
Exceptionally low extreme maximum temperature of
only 23.4C, but beaten in 1988 with 22C, and 1974
with 22.6C.
Harborne S.: A remarkably wet month most remembered for
the severe flooding around Tewkesbury, Gloucester
and parts of Oxford. Wettest month on record and
since 1951 in the area, the third wettest month in
this area behind November 1951 and November
1929 since before 1900. 23 rain days equal with
1988 as the highest on record for July. Jan - July
rainfall is 718.9mm easily the wettest such period
on record with its nearest 'rival' being 1988 with
567.6mm. Evaporation lower than in April. 2 days
with hail is highest total for July in 23-year record.
Coolest July since 1988.
Warstock: Wettest July locally (24 year record). Third
successive month to establish rainfall record for the
respective month.
Halesowen: With 181.1mm of rain this has been the wettest
July and the third wettest single month since
records started in Halesowen in 1956. The total
rainfall for May, June and July has been a record
485.9mm (beating the previous highest 294mm in
1968). Total rainfall for the year so far is already
708mm (our annual mean is 779mm). The 20th
brought 68mm, the fourth highest fall of any day
here (previous highest was 74.9mm on 19.8.1970).
A cooler July than usual, although 12 other years
have been cooler. It was mostly cloudy until 15th,
then a brighter and sunnier until 19th. Cloudy, dull
and very wet 20th-21st. More sunny periods from
22nd-27th, and a long overdue summer-like feel
from 28th-31st.
Alvechurch: A very wet month (194.7mm). The wettest single
month since records at this site (1989). 77.8mm fell
over 24 hours on 20th, and 92.3mm over 35-hour
period from 1800h/19th onwards.
Telford, Priorslee: By the 28th we had reached the average
1
annual rainfall total of 740mm for the year.
Harriseahead: The wettest July on record (1982), and
second wettest of any name after August 2004.
Newcastle-under-Lyme: July was the wettest on record here
(1977).
Weston Coyney: Highest number of rain days and wet days
on record (1960).
Loughborough: The extremely wet month caused extensive
flooding in the Soar Valley. The centre of the town
had flooding that transformed our 'Queens Park'
1
Correction to June 2007 page 22: Telford, Priorslee: two
day totals were 67.6mm 14th/15th, 68.6mm 18th/19th,
68.9mm 24th/25th.
21
into a lake after the heavy rain of the 20th/21st - not
seen before in living memory.
Cosby: A cold and very wet month with sunshine just below
normal. Wettest July since 1932 and the coldest
since 2000.
Mountsorrel: Rainfall total at 155mm made this the wettest
July in my 10 years here! Extensive flooding in the
Soar Valley on frequent occasions. Afternoon
temperature of 19.6C was 2C below normal. First
cooler than average month since March 2006.
Lowdham: The wettest July since 2002 with the annual
rainfall amount being reached on the 20th. The 12month running total of 1014.4mm is the highest in
the Nottingham area since 1872 (1026.2mm at
Highfield House).
Radcliffe-on-Trent: The wettest July since 2002 and the third
successive month with more than 100mm of
rainfall. 43.5mm on the 20th made this the wettest
day of any month since 25.8.1986 (ex-Hurricane
Charlie).
Calverton: Another very wet month with temperatures below
normal.
Southwell (Norwood Park): Coolest July since 1988, with the
lowest monthly maximum temperature of only
23.2C also since July 1988. A very rainy and rather
cool month. The maximum temperature on the 21st
of only 13.0C was also one of the lowest recorded
for some years. The first time on record (1748) that
over 100mm of rainfall has been recorded on three
consecutive months in the region.
Keyworth: Atlantic low pressure systems coming in from the
west one after the other gave the area another very
wet and cool summer month with over twice the
normal rainfall falling on 20 days. On the 11 dry
days, however, we did manage to notch up normal
sunshine amounts. The rainfall was very heavy and
thundery at times with flash flooding locally.
40.2mm fell in 24h on the 20th for example.
Thunder was heard on 9 days which is a new
record for this station. The weather did improve
towards the end of the month as high pressure
moved in at last.
Middleton: The mean temperature was the lowest since
2000, which it equalled, and the mean maximum
was the lowest since 1993. The highest maximum
temperature was the lowest since 1988. It was the
wettest July on record by a margin of 0.1mm over
2003 (records began in 1977) but on a composite
local record 1973 was wetter. 22 rain days was
exceeded in 2004 but with only 50% of the rainfall.
It was the dullest July only since 2005 thanks to
several sunny days during the final week. The
mean air pressure at 0900GMT was the lowest
since 1988. It was the windiest July since 1998.
Wirksworth: The coolest July since 1993 by mean
temperature and the mean maximum was the
lowest since 1988. The highest maximum
temperature was the lowest since 1998 which it
equalled. It was the wettest July since 1973 on a
composite local record. Hail fell during a heavy
shower on the 15th, only the second instance of
hail in July in the last 20 years.
Derby: The coldest July since 2000 but January-July 2007 is
still the warmest such period on record and also the
wettest such period (594.9mm).
July 2007
Rosliston: Wettest July (135.5mm) on record - its nearest
rival being 2001 with 105.1mm. Cool overall, with
just 7 days exceeding 21C, none over 25C. 23 rain
days was most in July and only one less than most
on record for any month here!
Ashover: The wettest July since 126.1mm in 1973 and the
second wettest on record (1966). The last 12
months have been the wettest 12-months on record
with 1186.9mm (137% of average).
Newhall: The month of July has given Newhall another
record high rainfall total (1970). The washlands at
Burton are still slightly underwater with huge
expanses of mud left behind by the last series of
floods.
Auckley, Doncaster: Only July 2002 was wetter here (by just
2mm).
Doncaster, Cantley: The first month since March 2006 with a
below average value for the mean temperature. A
wet month again.
Castleford: Coolest since 2004, and wettest July since 1930.
East Ardsley: A cool month with mean temperature 4.4C
below that in 2006. Quite a cloudy month
dominated with winds and weather systems from
the SW. Some heavy rain at the start and middle of
the month.

Louth: Wettest July since records began in 1981. The lowest
absolute day maximum temperature (24C) for July
since 1988.
Leconfield: Wettest July and the lowest July maximum
temperature on record (1992). Windiest July since
before 2001.

Whitby (West Cliff): Coolest July since 2004. Mean
maximum temperature 4.1C lower than July 2006,
and the mean temperature was 3.0C lower than
July 2006. A wet July but out of the last four Julys
only July 2006 was drier than average. 21 rain days
only beaten by 22 in Julys of 1998 and 1988. 14
rain days only equalled in July 1998. 23 July was
the first completely dry day since 20 June. The
windiest July since 1998.
Carlton-in-Cleveland: Wettest July (138.2mm) just beating
July 1988 (135.7mm); equal most no of rain days
(21) with Julys of 1988 and 1998. Coolest July
since 2000 and the first appreciably cooler than
average month since March 2006. The highest
temperature, 22.0C/31st, was lowest in any July
and cooler than April's (23.7C/15th) warmest day
and also last July's mean maximum temperature
(25.3C), which was a staggering 6.1C hotter than
this year.
Carlton-in-Coverdale: The coolest July since 2000. The
wettest July since 2002. The lowest mean pressure
since 1988.
Pateley Bridge 2: The coolest July since 2000. The mean
maximum temperature was 6.4C lower than in July
22
2006. It was the first month since March 2006 with
a negative temperature anomaly. The wettest July
since 1988. The rainfall for January to July 2007
has been 50% above average (an excess of
268.7mm). Nearly a quarter of July's sunshine
came in the last 3 days of the month. The mean
pressure at 0900GMT was the lowest in July since
1988.
Ripley: A wet month but far less so than in June. Cool
throughout with little variation in temperature from
day to day.
Redcar: The coldest July since 2000 and the third wettest on
record (July 2005 was much wetter). The highest
maximum temperature of 23.5C was the second
lowest on record after 21.6C in 2000.
Normanby: Mean temperature (16.3C) was lowest since
2000 and at -0.7C from the 30-year mean was first
month with a negative anomaly since August 2006.
10 days with maximum temperatures over 21.1C
(27 last year); 20 days last year had a maximum
temperature which exceeded this month's absolute
maximum (23.5C). 122.9mm made this the second
wettest July here after 134.6mm in 1988. There
were 19 rain days (equalled in 2002), but 20 in
1998. Total rainfall for June and July (246.1mm,
214% of mean) and May, June and July (300.2mm,
182% of mean) are all highest such values here.
Sunshine totalled 155.3h, and was boosted by
45.4h in last 5 days, although it was sunnier than in
2005. For the months of May, June and July the
deficit from the 30-year mean is 1h/day.
Marton, Middlesbrough: The wettest June-July on record
(1971) with 221.8mm.
Skelton Green: The unsettled weather continued throughout
July. The first week produced frequent heavy
showers with several thunderstorms scattered
through the afternoons. The lack of sunshine and
frequent showers made the whole month feel more
autumnal than summery, particularly when the night
time temperatures slipped down into single figures,
during the last week. It was only in the last 3 days
of the month that things started to settle down and
temperatures started to pick up.
Westgate-in-Weardale: The first below average month for
temperature for some time. Rainfall nearly twice
normal continuing wet theme.
Copley: Dull, cool, wet and breezy. The coolest July since
2002, temperature did not reach 70F (21.1C). Only
three days topped 20C compared to 26 last July.
Just 1 day above 20C at the Lead Mill. The second
wettest July in my 37-year local record after July
1988. Surprisingly, five of the past seven Julys
have been duller, but just half the total sunshine of
last July was recorded this month. Breeziest July
since Davis AWS system installed in 1998.
Spittal: Not quite as grey and murky as June - at least we
saw something of the sun, usually during
afternoons. Nevertheless this was another very wet
month with two exceptionally wet days on the 5th
(19.8mm) and 21st (31.6mm). The running total
rainfall for 2007 is now 400.3mm compared with the
long-term average of 296.0mm (35% higher than
normal). When the sun did appear, the daytime
temperature topped 20C on 10 days. The averages
of both maximum and minimum temperature were,
despite the cloud and rain, above the seasonal
normal. Winds were generally light and from a
July 2007
23
westerly direction. Brief spells of northerly winds
made conditions more like autumn than summer the daytime temperature crawled to only 13.7C on
the 21st in a fresh northerly breeze.
Northwest England
Timperley: By far the wettest July on record (1990).
Hunts Cross, Liverpool: The wettest July on record, 13mm
than in the previous wettest July of 1958.
Heswall 1: The wettest July on record, although not as wet
as in June. It was a miserable month with much
heavy cloud, although we were spared any
exceptional daily falls of rain.
Todmorden: The wettest July on record (1971); locally July
1939 had more rain (196.6mm).
Burnley: A dreadful July, both cold and wet. There was not
one completely dry day from 11 June to 29 July (48
continuous days with rain).
Morecambe: 176mm of rain fell this month.
Huncoat: The warmest day reached only 21.5C, 6.1C below
what might be expected! Wettest July for 19 years.
Coolest July for 9 years, the biggest factor being
the lack of any really warm days,
Radcliffe: Wettest July since records began (1989). Highest
number of rain, wet and thunder days since records
began (1989). Coolest July since 2000 and the
highest maximum temperature (23.3C) was the
lowest since 1993 (23.2C).
Oldham: The first time July has been cooler than June since
1992. July 2006 had only 4 days with a maximum
temperature below 20C, this year only one day had
a temperature over 20C. Coolest July on record
(1978), with the most negative anomaly since May
1996 (-2.5C). The third wettest July on record after
1988 and 2002. The combined June and July
rainfall of 308mm is the highest on record.
Rochdale: 40.5h of sunshine on the last four days pushed
the sunshine total from 51.2h to 91.7h, just above
the lowest total recorded (since 1947) set in 1965
90.4h.
Seaton: Locally it was a dry month; this was largely due to
missing out during the showery weather on several
occasions when there was heavy downpours only a
few miles away such as on the 18th, 19th and 23rd.
High Carley: Wettest July on record at this station. Lowest
number of dry days in any July at this station.
There's no doubt that this was a wet month by any
standards, but it could have been much wetter with
a couple of storms scoring a "direct hit" at my
station - despite 4 thunder days, the wettest day
recorded a paltry 17.6mm.
Lowest mean
temperature at this station (in 10 years).
Total rainfall for May-July is 398mm (200% of
average). Dullest July since 1986. Lowest
barometric pressure recorded on the 1st since
records began.
Burton, Rossett: Extensive cloud cover locally during the
month.
Velindre, Brecon: It was the second wettest July (after 1939)
in composite local records since 1885, and the
May-July period produced the highest rainfall total
(351.2mm) for the three months combined, just
beating 1903.
Pembroke Dock: Wettest July since 2001.
Swansea City: The wettest July since 1988; localised
flooding occurred at times.

years. The second wettest July in 46-year record.
Cardiff, Llandaff: Since 1990 this was the wettest July,
previous wettest July gave 148.7mm in 1993. Since
1990 only 15 wetter months with wettest having
305.4mm in October 1998. Wettest day only
recorded 26.5m (on 13th) but 33.8mm fell during
0600-1800GMT on 26th.

and the lowest mean maximum temperature since
1998.
Ireland
Helen's Bay: Rainfall total on 13th (25.9mm) was heaviest
fall on any July day since 1992. 22 rain days is
most for July since 1988. The first month with below
average temperatures since March 2006. Average
pressure was the lowest for July since at least
before 1981.
Galway: June-July 2007 was the wettest since records
began in 1880 and had the wettest July since 1936.
July was the first month since March 2006 with a
lower than average monthly temperature.
Dun Laoghaire, Dublin: Wettest July and greatest June-July
rainfall total on record. The most cyclonic July since
1988. The most cyclonic June-July period on
record. 6 days with thunder (normal - 0.5 days).
The key unsettled period was the six weeks 14
June-26 July.
Ashford, Co. Wicklow: Maximum temperature of 22.2C is
lowest since 2000 for July. As with June this was
the first July first time to record more than 100mm
making it my wettest summer on record even
without the August total (1999). 24 rain days is
second highest total on record for any month
(1999).
Dublin, Phoenix Park: June-July rainfall total of 297mm is
the highest in the 170-year record.
Wales
Mullingar: Wettest July since 1960.
Red Wharf Bay: The wettest July in 40-year record.
Scotland
Pentraeth: Wettest July at this station so far (1998),
breaking a run of quite dry Julys, but not
excessively wet with 116.7mm and wettest day with
only 18.2mm. First half of month very dull then
second half somewhat brighter. With a high
maximum temperature of 21C no day reached the
July mean maximum of 2006.
Ollaberry: The coolest July of the last four, with the least
sunshine, most cloud and highest humidity. It was
also the wettest July with 133mm of rain.
Moel-y-Crio: The third coldest July on record, only beaten by
1998 and 1988. Wettest July since 2000 (159mm).
Loch of Hundland: July 2007 was a sharp contrast to June
2007 and July 2006. Whereas June was dry July
2007 was the wettest July since Orkney records
began in 1841; it exceeded the 1891 rainfall by
12.8mm and about a quarter of the total fell on one
day. The average temp for the month was 3.1C less
July 2007
than in July 2006. The sunshine was just over half
of July 2006.
Aberdeen, Hazlehead: Another very poor summer month.
The first June/July since 1910 to fail to reach 21C,
locally, was just avoided with a maximum
temperature of 22.9C on the 31st - being the first
reading over 21C since 23 May.
24
1988, with 14. July rainfall has jumped markedly
since 1999. The average for the last eight years is
now up to 58.3mm and in that period only one in
2001 has had less than the average July rainfall.
We still had 36.4mm that year, only 1.5mm below
the long-term average.
Ardtalnaig: Hay and silage making done in fits and starts,
the quality usually lacking but the growth of grass
and weeds was generally excessive and the land in
many cases was as wet as would be expected in
late autumn.
Kennoway: Coolest July since 2004. May-July combined
mean temperature is lowest since 2000. The
second half of month was 1C cooler than first half.
Wettest and most cyclonic July since 2002. Rain
fell everyday from the 13th onwards. The 1st-4th
had 4 consecutive days with thunder, a new record
(1988). Yet another dull month.
Belliston: Wettest July since 1957.
Cowdenbeath: Another wet and rather cool summer month
with a mean temperature about 0.6C below my
estimated average, thanks in part to some relatively
chilly nights for the time of year. At least there was
more in the way of sunshine than in June, due to
the reduced prevalence of winds from an easterly
compass point. Highest temperature of the summer
thus far is a measly 20.8C.
Carnbo: A very unsettled, wet and cool month. The 19th was
a very bleak day for July with a maximum
temperature of 11C. The 17th to 20th were
completely overcast in E'ly wind conditions. The
temperature failed to reach 20C this July, cf. 18
days with 20C in July 2006.
Scalasaig, Colonsay: We have now enjoyed 6 dry months in
a row.
Helensburgh: A very dull month with persistent cloud cover
and very little sunshine. Rainfall was light except on
the 1st, 13th and 25th.
Elderslie: The 14th coldest and 10th wettest July in 38-year
record. The first month since April 2006 to be
cooler than average.
Wishaw: A rather cool July when compared to recent ones,
but only just below the long term average, however
it is the only month of the last sixteen to return a
negative anomaly. Rainfall, like in June, was above
average, but not remarkably so here. And a rather
bright end to the month has led to us surprisingly
recording above average sunshine.
Corsock: The first month for some time with below average
temperatures. The absolute maximum temperature
was 21.1C was the lowest since July 1998. Rainfall
tended to be in the form of sharp showers. Until the
last four days of the month, it looked like being the
dullest July on record but the sunny end lifted
sunshine totals to the fourth least sunny month in
the record.
Funnel cloud seen over Guernsey, 31 July 2007.
Guernsey Airport: The mean pressure at 0900GMT of
1014.1mb was the lowest since 1988 and the
second lowest on record. The mean wind speed
was the highest since 1998. The total of 20 rain
days tied the July record from 1960 and 15 wet
days tied that record from 1950. Over the three
months of May, June and July we have had
244.1mm. In Airport records 1986 comes closest
with 233.4mm. It is necessary to go back to 1894 to
find a wetter May-July period. We have, though,
had less than 100mm in each of the last three
months, whereas large areas of England have
recorded more than 100mm in each of the last
three months.
Guernsey, L'Ancresse: This was the coolest July since 2002
and the wettest since 2004. 20 rain days and 14
wet days were both new records for July. In only
four years have there been more than 10 wet days
in July.
Sark, Point Robert: This was the coolest July since 2002, the
wettest since 1980 and the dullest since 2004.
May-July rainfall 221mm, highest on record.
Carrefour/Clercq, Jersey: The coldest July since 1998.
Summaries from abroad
Bilthoven: Only 8 completely dry days from 9 June to 31
July.
Akrehamn: Coldest, wettest and dullest July on record
(1993).
Channel Islands
Frederikssund: Cool and dull. Precipitation sat an all time
new high record for any month with 172.5mm. The
5th with 58.0mm set a new high daily record for any
month. 22 rain days was a new high record for July.
Total precipitation for June and July was 310.9mm,
265% of average. Mean air pressure was
1007.8mb, the second lowest on record for July;
1965 had 1007.5mb.
Rocquaine, Guernsey: This was the coolest July since 1998.
Only those of 1988, 1993 and 1998 have been
cooler. This was the wettest July since 2004 and
the second wettest on record. 21 rain days and 16
wet days were both new records for July. The only
other July to have more than 10 wet days was in
Plettenberg Bay: Temperatures were slightly below normal.
However, there were some episodes of hot and
sultry weather. The period between the 8th and the
11th was very uncomfortable. The last week was
also humid with high night time minimum
temperatures. Precipitation was above normal.
July 2007
Thunderstorms brought heavy showers on the 11th,
18th and the 24th.
Kempton Park: A very sunny month with mostly cloudless
skies from the 13th to the end and with an average
daily temperature range during this period of 19.9C.
Mt. Waverley: Only a very slow recovery from the El Nino
drought of 2006: January-July rainfall (78% of
average) the lowest in Mt Waverley since 1997.
Recent weather events around the globe
1st-6th: Eastern states of West Bengal and neighbouring
Orissa have been battered by heavy downpours for six
days, sparking fresh flooding which has left hundreds of
thousands of people marooned. A large number of
people continue to remain cut off from the rest of the
country after surging river waters, broke through mud
embankments and swamped villages. In Calcutta, civic
authorities have been completely overwhelmed with relief
work after the city received 475mm of rainfall in four
days.
3rd: The number of deaths caused by the heatwave in
Greece, which lasted some 10 days, has risen to fifteen.
Since 29 June, temperatures have returned to the
seasonal norms, having reached 46C in Athens. The
fires which had been burning in several parts of the
country since last Wednesday are now all under control.
4th: A total of 61 people lost their lives as a result of heavy
rainfall, which is expected to continue across India,
raising the death toll in the country to 294 since the
beginning of this year. West Bengal, Gujarat,
Maharashtra and Madhya Pradesh have been among the
worst monsoon-affected states during the last 10 days.
5th-7th: Torrential rains and gale force winds have lashed
southern parts of Japan killing one and injuring four, as
well as causing widespread flash flooding and triggering
landslides. Nearly 3,400 residents in Kumamoto have
been urged to flee their homes due to a river breaking its
banks, cutting off roads. Other neighbourhoods in
mountainous areas have been isolated by the floods.
One of the worst hit areas was the small town of Misato
located south of Tokyo, where hundreds of homes were
isolated by flooded roads and a landslide. Over 200mm
of rain fell in some parts of Kyushu in southern Japan
since Thursday night.
7th: A heatwave affected areas across the western
contiguous U.S. during the first week of July.
Temperatures were past 40C across the western U.S.,
breaking maximum temperature records in several cities.
These dry and hot conditions throughout much of the
western U.S. enhanced wildfire potential, with several
large fires scattered across the region during early July.
8th-14th: Typhoon Man-Yi developed as a depression in the
western Pacific Ocean on the 8th, reaching typhoon
intensity by the 10th. Early morning on the 13th, Man-Yi
made landfall in the southern island of Okinawa with
maximum sustained winds near 160km/h. The strong
winds left more than 60,000 people without power. On
the 14th, Man-Yi made landfall on the southern part of
the islands of Kyushu and Shikoku and immediately
weakened as it tracked toward the northeast. Typhoon
Man-Yi was responsible for 5 fatalities and was
reportedly the most powerful storm to hit Japan in July
since records began in 1951.
9th: Cold weather in Argentina resulted in the first major
snowfall since 1918 snowfall in Buenos Aires. According
25
to the local meteorological centre, this is the first time
since 1973 that Buenos Aires experienced any snowfall.
The snowfall was linked to a mass of freezing air from
the Antarctic which collided with a low pressure system
that swept across the capital and surrounding area.
11th: Winds, blizzards and rare snowfall hit various
provinces in South America causing the death of three
people in this unusually cold winter season. Over the
past week authorities in some countries, e.g. Argentina,
Bolivia and Chile, were forced to take measures to ration
energy supplies and in Bolivia and Peru a state of
emergency has been declared. Temperatures reached
as low as -22C in Argentina and -18C in Chile.
12th: Heavy monsoon-related rainfall caused landslides that
killed at least 26 people in western Nepal. Six people
remain missing.
15th: High temperatures in Hong Kong have caused a spate
of heat-related illnesses across the city At least 80
elderly people have been taken to hospital suffering from
conditions such as heatstroke. An 88-year-old woman
collapsed in a shopping mall and was pronounced dead
before arriving at hospital. Residents have been advised
to stay indoors while the hot weather persists.
16th: The Australian state of Victoria has been covered by
snow as a cold snap hits the region; several areas have
been affected by the snow, which has been compounded
by the high wind chill factor. Motorists were warned to
take extra care on the roads as many of the surfaces are
icy, while many of the road markings have been
completely obscured. The conditions have led to several
minor accidents, mainly as a result of cars losing grip
and skidding.
17th: Severe thunderstorms over the past few days have
created a powerful duststorm which is moving across
parts of Arizona in south-west America. Winds of around
47mph were reported in the city of Chandler near
Phoenix, which kicked up the sand into a duststorm. As
the storm passed, temperatures in the city dropped from
43C to 33C in just over an hour, with the increase in dust
reducing the visibility on many roads. The high
temperatures and humidity across the state created ideal
conditions for a storm, with the warmest ever minimum
temperature of 33C recorded in Phoenix on Monday
night, 3C higher than the previous one.
18th: Heavy rain which began in June 2007 across parts of
China continued in July. During the first week of July,
torrential rainfall generated devastating floods and
landslides which affected about 500,000 people in
Jiangsu, Anhui, Henan, Hubei, Sichuan, Shaanxi, and
Chongqing provinces. About 94 fatalities were reported
with 25 others missing. The floods and landslides also
destroyed about 49,000 homes and damaged
approximately 240,000. During 15-18 July, severe storms
pounded central and eastern parts of China, which killed
at least 37 people mainly due to mudslides and lightning
strikes. In Chongqing city, an intense thunderstorm
produced heavy rains which triggered flooding that
affected about 113,000 people and destroyed about
10,000 homes. On 16-17 July Chongqing received,
according to reports, 227mm of rain in a 24-hour period.
This amount of rain broke the previous record of 206mm
that was set on 21 July 1996 and thus became the
largest volume in a 24-hr period since records began in
1892. Economic losses have been estimated to exceed
$500 million.
18th: Authorities in Hungary are distributing thousands of
gallons of water as the country's heatwave continues.
July 2007
Budapest is currently experiencing temperatures of more
than 38C. As a result, Budapest's city council has sent
out teams of municipal workers to distribute 22,000
bottles and 15,000 plastic bags of drinking water to local
people. Meanwhile, water trucks are cooling streets and
pavements and the city's transport company is delivering
water to passengers at bus stops.
18th: High temperatures in Bulgaria have caused damage to
some of the country's transport infrastructure with tram
rails in the capital city Sofia buckling in temperatures of
40C.
18th: Strong winds In Finland have left a trail of destruction
across the southern province of Kymenlaakso, which
was lashed by winds that were strong enough to uproot
trees. The town of Valkeala was badly affected, as trees
were brought down over a half-kilometre stretch by a line
squall. A number of buildings were also damaged as
roofs and windows faced the force of the gusts, as well
as impacts from falling trees and branches.
20th-21st: Violent thunderstorms have caused destruction
and death in northwest Pakistan. Officials say that more
than 80 people have been killed, including women and
children, as lightning, flash floods and landslides batter
villages in the remote Usherai Darra area of the country.
Over 20 homes were washed away on Friday evening in
the flood waters. Rescuers have confirmed the death of
around 70 people so far, but feared the number of dead
could increase, with scores of people still missing. On
Saturday torrential rain caused landslides which
damaged more homes in the villages and blocked off
roads, hampering rescue operations.
23rd: Parts of South and Central Texas finally got a break
from the torrential rain that flooded roads, stranded an
Amtrak train and sent Boy Scouts fleeing for safety. As
much as 17 inches of rain had fallen in some areas
between 10 p.m. Friday and 10 a.m. Saturday. Dozens of
people were rescued, some by helicopter, but no serious
injuries were reported in the state's latest round of
flooding. The sun peaked out by midday Sunday.
23rd: Thirty-two people are dead and 5,000 have fled their
homes in Indonesia after floods and landslides caused
by heavy rains demolished homes and severed transport
links. Entire villages are cut off by the disaster in Central
Sulawesi after torrents of mud and water destroyed
several bridges following a week of downpours.
23rd: The capital of Brunei has been disrupted after a major
storm hit the city. Bandar Seri Begawan was lashed by
strong winds and heavy rain. This caused damage
across the area, as parts of buildings, stalls and other
structures were brought down. Meanwhile, power was
cut off and some roads were blocked by the fallen debris
such as trees and signs.
24th: Authorities in the Balkans warned people to stay
indoors to avoid searing temperatures that have already
killed 30 people in Romania and two in Bulgaria and
Greece, with another two deaths reported in Croatia.
Temperatures in the region were recorded at 40C and
above, with Greece expecting a high of 45C on Tuesday
and Italy just behind at 44C, hours after Rome recorded
one of its warmest nights ever on Monday at 27.1C. On
the same day, Bulgaria experienced its hottest
temperatures since records began with the mercury
shooting above 45C in parts of the country, while more
than 860 people reportedly fainted in the streets in
Romania. The heat also fanned several fires, with the
most serious on Tuesday raging near the southern
Macedonian city of Bitola. One person died and
26
thousands were evacuated as the blaze laid waste to
some 1,000 hectares of forest near Macedonia's secondlargest city. Greece was also recovering from a season
of blazes that in the past month have devastated 32,000
hectares.
26th: Large chunks of ice, one of them reportedly about 50
pounds, fell from the sky in Iowa, smashing through a
woman's roof and tearing through nearby trees.
Authorities said they were unsure of the ice's origin but
have theorized that the chunks either fell from an
airplane or naturally accumulated high in the atmosphere
- both rare occurrences. "It sounded like a bomb," said
Jan Kenkel, 78. She said she was standing in her kitchen
when an ice chunk crashed through her roof early
Thursday morning. "I jumped about a foot!" She
discovered a messy pile of insulation, bits of ceiling,
splintered wood and about 50 pounds of solid ice.
Neighbours Karle and Mary Beth Wigginton said they
heard a loud "whoosh" coming through the trees,
discovering several large chunks of ice in front of their
home in this city in northwestern Iowa in the country's
Midwest.
31st: Much of China was inundated by the worst rains of the
year, testing the Three Gorges Dam's anti-flood capacity,
even as over a million people suffered from serious
drought. In northwest China's Shaanxi province, 21 were
confirmed dead and 18 others were still missing in floods
triggered by heavy downpours that began on Saturday.
More than 700 people have been killed by floods,
landslides and lightning this year in China. On Monday,
the International Federation of Red Cross and Red
Crescent Societies described this summer's inundations
as "some of the worst flooding to hit the country in the
last 10 years." The capital Beijing was also hit by the
heaviest rainstorm this summer on Monday, causing
serious delays at the city's international airport and
stranding about 10,000 passengers. In central China's
Hunan province, sustained drought for the past four
months had triggered a water crisis for 1.2 million
people. China's largest city Shanghai is also sweltering
through what is likely to become its hottest summer on
record.
31st: Floods and heavy rains have caused 23,000 mud brick
homes to collapse and killed at least 62 people across
Sudan this month. The homes of over 40,000 families
were damaged in northern Sudan alone, and tens of
thousands of cattle have been lost. Most of the north is
arid, and many houses are constructed in local materials
that can't resist strong rains. At least 140 public
buildings, including schools and hospitals, have been
heavily damaged and major roads have also been cut
off. Tens of thousands have also been displaced by the
flooding in southern Sudan, and top local officials have
recently declared the south a disaster zone.

Heavy July rainfall in Thatcham
The Met Office were issuing warnings when I went to bed at
4am on the 20th following a week away from home working
nights. The next I know is the rain waking me at 1030am, I
looked out of the then open window and quickly closed it as
July 2007
the carpet was getting wet. At 1130am the noise again
woke me, so I started to wonder if the rain that was falling an
hour ago was a dream. I checked the weather station and
presumed it had gone wrong as the rainfall was very
unusual! Later studies showed the rain fell at over 25mm
per hour 0950-1210GMT and the peak hourly rate was
34.9mm/h at 1130GMT. The total rain for the 00-24 day was
97.3mm with a rolling 24-hour period maximum of 100.4mm
from 1410GMT on the 19th.
To put these numbers into context, in the last 5 years my
maximum daily rainfall was 35.0mm (May2007), but it also
fell constantly over the 24 hour period. The station tends to
get just a few 25.0+mm events per year, and those are
notable. But not only did 3 times as much rain fall, but the
majority fell in a three hour period during the morning. No
wonder the drains could not cope, and no wonder streams
that had been put into pipes once again found there natural
course causing homes including bungalows where they
appear to have lost everything considering the amount of
furniture still stood in front gardens as I type on the 12
August. My two manual (back up) gauges overflowed as
although of differing design only record 50mm and my two
hail gauges were also punctured by the rain intensity.
Fortunately my home is 'slightly' higher than a number of
surrounding homes so we survived, but quite a lot of
Thatcham suffered.
The A4 just south of here had
emergency service sirens blasting out for around 6 hours.
That afternoon I attempted to reach the centre of Thatcham
one mile away, but roads were blocked by floods,
abandoned cars on now wet roads or impassable due to
drain covers and the surrounding road lifting. This was also
27
like a dream, and at 5pm there were 'live' feeds on BBC
News24 from helicopters above Thatcham. This was during
the time the rain had moved to the Gloucestershire region
and News 24 moved there for the rest of the month.

The June/July 2007 summer rains
Readers may be interested in the following, taken from the
http://www.met.reading.ac.uk/~mike/autumn2000.html
website of Dr Mike Blackburn of the University of Reading.
The website also shows several animations which are worth
seeing.
During much of June and July 2007 the Atlantic jet-stream
was displaced equatorward of its normal position
(comparison). At the same time, a quasi-stationary wave
pattern persisted from the north Pacific over north America
and the Atlantic to Europe, with an upper-air trough close to
the UK.
This large-scale environment led to weather systems
tracking further south than normal towards the UK, and to insitu developments associated with the upper-air potential
vorticity anomaly over the UK.
The potential for heavy rainfall on 20 July was well-forecast
in advance by the Met Office – indicating that it was a
meso/large-scale rather than small-scale forcing that caused
the precipitation. The Herstmonceux soundings for
0000GMT and 1200GMT on the 20th are shown below.
July 2007
According to Mike, ahead of the system at 0000GMT, the
atmosphere was close to moist-neutrality, almost saturated
through the depth of the troposphere, with total column
water vapour of about 30kg/m2. The sounding is unstable to
a relatively small amount of lifting. By 1200GMT drier air
aloft has reached Hestmonceux.
http://www.ceh.ac.uk/news/BriefingnoteJuly2007Floods.html
provided by the Centre for Ecology and Hydrology, notes:
The combined May and June rainfall total is the highest
on record for the UK (in a series from 1914) by a
considerable margin and the exceptional weather
conditions continued into July. Provisional data indicate
that the May-July period will be the wettest for England
and Wales in a series from 1766 with many areas
registering more than twice the long term average remarkable for a three-month period.
As warm and very moist air moved north from France,
the volatile July weather patterns culminated in an
extremely wet episode on the 20th. Outstanding storm
rainfall totals were reported across much of southern
Britain. These included 145mm in Pershore (Hereford
and Worcestershire), 111mm at Chieveley (Berkshire)
and about 120mm at Brize Norton (Oxfordshire).
Statistical analyses confirm the extreme nature of such
storms - on the basis of historical data they would be
expected to occur, on average, only once in several
hundred years (longer in the case of the Pershore event).
Thundery interludes contributed to substantial spatial
and temporal variations in rainfall intensity but catchment
rainfall totals were exceptional over wide areas.
28
Localised storms of tropical intensity are a feature of
many
English
summers
but
a
distinguishing
characteristic of the July 2007 storms was the spatial
extent of the extreme rainfall totals.
Normally, flood risk during the summer is substantially
diminished by dry soil conditions. Following the record
late spring and early summer rainfall, accompanied by
widespread flooding in June, soils were close to their
wettest on record (for mid-summer) in early July across
much of England. This rare circumstance left many
catchments vulnerable to further significant rainfall.
The exceptional rainfall on the 20th July triggered a
sequence of relatively distinctive flood episodes:
localised (mostly urban) flash floods, extremely high
flows in small responsive (impermeable) catchments
and, subsequently, extensive floodplain inundations as
the runoff concentrated in the major rivers of southern
Britain (including the Severn, Warwickshire Avon,
Bedford Ouse, Trent and Thames).
Initially, the intense rainfall overwhelmed many urban
drainage systems producing localised but severe flash
floods. The emergency services were widely deployed to
rescue stranded individuals and organise evacuations
from the most severely affected localities.
These
contributed to massive and extensive transport disruption
across southern Britain, exacerbated by the volume of
holiday traffic (the 20th being the end of the school term
in many areas). Subsequently, floodplain inundations
caused extensive crop damage and the need to move
livestock to higher ground. The sustained high levels in
July 2007
29
the major rivers also hampered the drainage of flood
waters away from the urban areas inundated on the 20th.
4. The stationary nature of the jet stream-level anomaly
contributed to the long duration of intense rainfall.
Preliminary data suggest that a significant minority of
rivers across southern Britain exceeded their previous
maximum recorded flow and many eclipsed previous
maxima for the summer half-year (April-September) often by very wide margins.
5. Ball-park estimation of column moisture and
implications: approximate the maximum total column
moisture by the surface saturated humidity (qsat) in
200hPa of the lower atmosphere. How much rain comes
from condensing it all in-situ over a region? Surface
temperature 20C, qsat = 15g/kg, giving 30kg/m2 or
30mm of rain. So 100mm, exceeded over Oxfordshire
and W. Midlands, needs all the water vapour to
condense from an area several times larger than the
rainfall footprint. This requires convergence maintained
over many hours, implying large-scale and mesoscale
(frontal) organisation.
In the worst affected areas (e.g. in the lower parts of the
Severn and Warwickshire Avon basins and some upper
reaches of the Thames catchment), flood flows may have
exceeded those of March 1947 - the most severe flood in
southern Britain in over 100 years (note however that the
1947 event was primarily the result of rapid snowmelt
over still-frozen ground and its overall impact was
substantially more severe than the current flooding).
An indication of the rarity of the hydrological conditions
experienced this summer is provided by the recent
increases in groundwater levels in some parts of eastern
and southern England. Generally, groundwater levels
decline over the May to September period, due to an
absence of natural replenishment (recharge).
This
summer, groundwater levels in the Cotswolds rose
rapidly in mid-July and by the 24th stood above normal
winter levels; this is reflected in the exceptionally high
recent flows reported for many spring-fed streams. In
the 19th century, significant summer recharge was
recorded in a number of years (e.g. 1860 and 1879) but
examples of significant and widespread summer
recharge in the 20th century are very rare.
Episodes of extensive summer flooding may be found in
the historical record (e.g. in 1875) - particularly in the
nineteenth century when summer half-year (MayOctober) rainfall often exceeded that for the winter halfyear. There are, however, no close modern parallels to
the scale of the summer flooding experienced this year.
It has served to underline our continuing vulnerability to
very exceptional summer rainfall and to, as yet poorly
understood, changes in the position of the Jet Stream.

Persistent anticyclone and unusual weather in
November/December 2006 and June 2007
In the December issue of the COL Bulletin there were letters
from Jeff Blackshaw and myself regarding the unusual
rainfall amounts during November and December 2006 in
Elderslie and Berwick upon Tweed. Elderslie (55°N 50’N)
and Berwick (55°N 47’N) have similar latitudes and the
distance between them is about 160km as the crow flies.
The altitudes of the two sites are 50m (Elderslie) and 35m
(Berwick) but the most significant difference between the
sites is that Elderslie is on the western side of the UK
whereas Berwick is on the east coast.
I thought it would be interesting to compare the rainfall
amounts for different periods for Elderslie (given in Jeff’s
December letter) and Berwick – see the table:

http://www.walker-institute.ac.uk/news/summer_2007.pdf, a
press release by the Walker Institute notes that, regarding
the synoptic situation for the July floods:
1. A combination of the jet-stream anomaly south west of
the UK (the upper level trough, associated with a region
of high potential vorticity), together with low level
temperature and moisture contrasts between western
Europe and the Atlantic, appear to have provided the
forcing and organisation for the intense and prolonged
rainfall.
2. In the week preceding Friday's extreme rainfall,
northerly flow over Iceland had brought cold air at low
levels over the eastern Atlantic, which enhanced the
contrast with warm air over southwestern Europe,
providing energy (baroclinicity) for Friday's weather
system. On that day, ahead of the low, very moist, warm
air was transported over us that a few days earlier had
been over the subtropical Atlantic. There was a very
large temperature difference between the warmth of
Southern Europe and the cool air streaming southwards
to the west of the low. These were the ingredients
required for the large-scale, very heavy and prolonged
rainfall.
3. The air over the UK ahead of the system was warm
and almost saturated over the depth of the troposphere,
and was very unstable to daytime surface warming
and/or lifting, providing a copious moisture supply.

The table shows that the rainfall amounts are, on average,
about a factor of three times greater in Elderslie than in
Berwick in November and December but for this period in
2006 the factor was nearly 13. I suggested in my December
letter that one explanation for these contrasting rainfall
amounts was the presence of a large anticyclone during
most of the period over Northern and Central Europe.
During June 2007 there was a persistent anticyclone
between Scandinavia and southern Greenland, which I think
has been largely responsible for the very poor weather in
Berwick:
•

•
17 days with almost no sunshine
Every day a wind direction from between N and SE
(clockwise)
Rainfall total 79.6mm (176% of average)
Average maximum temperature 15.1C (0.8C below
average)
Highest maximum temperature 18.0C.
July 2007

The high pressure to the north and low pressure to the south
of the country has caused Berwick to be exposed to winds
off the North Sea all month, resulting in frequent mist (haar)
and low cloud.
Effect on earth temperatures of the heavy
rainfall on 20 July 2007 at Stratfield Mortimer,
Berkshire
If the positions of the November/December and June
anticyclones had been interchanged we would had a very
cold winter and a very warm summer in Berwick. Can
anyone explain why persistent anticyclones form in different
positions at different times of the year? The media suggest
that the reason for the poor summer this year is the
unusually southerly track of the jet stream. Does the jet
stream influence the pressure pattern or vice-versa?
The graph shows logged hourly mean earth temperatures at
depth 30cm (upper line) and 100cm (lower line) for July
2007. The heavy rainfall on 20 July (30.2mm in one hour,
64.3mm in 4 hours) resulted in rapid runoff and extensive
local flooding. The rapid penetration of relatively cold
rainwater and downslope runoff through the surface soil
resulted in a steep fall in the earth temperature at 30cm,
1.05C in 3 hours, more than twice as high as any previous 3
hour temperature fall at this depth on hourly records back to
November 2003. The most rapid fall occurred within an hour
of the heaviest rainfall. The cold water did not penetrate as
deep as the 100cm sensor, probably owing to clay deposits
about 60cm below the surface, as can be seen by the lack of
response at that depth.

Daytime adult education course: Weather and climate
for beginners
Weather - and its unpredictability - not only affects the
planning of our daily activities but also inflicts damage on
individuals and entire economies and societies. The
University of Reading's School of Continuing Education is
running a ten-week course providing an opportunity to
appreciate our dynamic atmosphere, understand causes of
severe weather, examine changes in the weather, including
global warming, and consider the methods involved in
forecasting.
The course will take place on Thursday
mornings from 11 October 2007 and will be led by Dr
Richard Allan (Environmental Systems Science Centre,
University of Reading). The fee is £79 (£49 concession).
