Timbo, Guinea, at lat. 10 N, West
Africa.
The line graph plots the
temperature for the abbreviated
months (J F M A M June, etc.)
The bar graph plots rainfall.
Combining the two gives us a
climograph, allowing us to get a
quick snapshot of the overall
climate at a glance.
This is a Wet-dry tropical /
Tropical Savanna (Aw)
climate:
A wet season alternates with
an almost rainless dry season.
"Savanna" vegetation
associations occur here -- "big
game" country of Africa.
Savanna = grassy plain with
scattered trees.
Characteristics
High-sun wet season, low
sun dry periods.
Rainfall less than monsoon.
Highest temperature ranges
of low latitude wet climates.
NOTICE THAT RAINFALL IS IN
MM not CM!
This is a dry savanna!

Look at the line graph for
temperature. What can you
observe? From this observation,
what might you infer?
Does the bar graph indicate, or
show, a dry season and a wet
season, or does it rain year-round?
From this observation, combined
with your previous observation,
what might you infer about the
climate for Mbandaka, Zaire?
Desert- dry year-round, little or no rainfall
Savanna- a wet season and a dry season
Rain forest- wet year –round
Mediterranean- warm summers and cool
rainy winters.
I hope you chose rain forest! It is rainy year-round. It is also tropical—look at
the temperature, and the latitude if it is given….
Now look at a climograph for Cairo.

Just for kicks, let’s look at a
climograph for Cape Town.
Look at the line graph for
temperature. What can you observe?
From this observation, what might you
infer?
Remember that South Africa is in the
Southern Hemisphere, so its warm
dry summer takes place in December,
January and February!
Then, its cool, rainy winter occurs
from May through August. Cape
Town, South Africa, like Casablanca,
Morocco has a Mediterranean climate.
Desert- dry year-round, little or no rainfall
Savanna- a wet season and a dry season
Rain forest- wet year–round
Mediterranean- warm, dry summers and cool,
