What is a Climate Graph?
- a climate graph combines a bar and a line graph
- It shows the average temperature and precipitation for each month in a certain place.
How to create a climate graph:Step 1:
- Climate graphs have 2 vertical axis’: the left shows temperature (C ) and the right shows precipitation (mm).
-Use pencil to make and label the axis’. Your scales can use different numbers if necessary.
How to create a climate graph:
Step 2: Use red to plot the average monthly temperature.
temperature
- Make a dot for the temperature in the middle of each space for the month.
When you have plotted the data for all 12 months, connect the points into a smooth, curved line.
How to create a climate graph:
Step 3:
Use the colour blue to make a bar graph of the monthly average amount of precipitation.

Step 4:
Make sure your graph is properly labeled

This is what it should look like when you’re done:
READING A CLIMATE CHART
The Climate Chart
Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Year
°C -26 -28 -24 -15 -4 4 8 7 2 -5 -13 -23

Reading Climate Charts• Climate charts provide the data that are
represented in Climate Graphs. They show the average temperature and precipitation for each month.
• What other information can be generated from a climate data chart??– Average annual temperature– Annual precipitation– Temperature range
Average Annual Temperature• Add all the temperatures together and divide by
12(total number of months)
• -10˚
°C -26 -28 -24 -15 -4 4 8 7 2 -5 -13 -23
Annual Precipitation• Add together all 12 months
• 418mm
mm 21 21 22 28 27 35 59 66 55 37 29 18
Temperature Range• Difference between the highest and lowest
average temperature
• 36˚– there are 28˚ below 0 and 8˚ above 0-
making the difference 36
°C -26 -28 -24 -15 -4 4 8 7 2 -5 -13 -23
INTERPRETING CLIMATE GRAPHS
Interpreting the Climate Graphs• FREEZING TEMPERATURE:
– Count the number of months that have an average temperature below 0° C.
• GROWING SEASON:– Count the number of months with an average
temperature above 5.6° C (mark as 6° C on the graph).
Interpreting the Climate Graphs• SEASON OF MAXIMUM PRECIPITATION:
• Add together total precipitation for each season
•
• WINTER = October, November, December, January, February, March
• SUMMER = April, May, June, July, August, September
• Determine which season has the highest level of precipitation.
Interpreting Climate Graphs• CONTINENTAL OR MARITIME CLIMATE:
– Look at the precipitation and temperature trends on your climate graph.
Criteria Continental(Away From Water)
Maritime(Close Proximity to
Water)
Temperature Range Greater than 25° C Less than 25° C
Total Precipitation Less than 1000 mm Greater than 1000 mm
Seasonal Distribution of Precipitation
Summer Maximum Winter Maximum
*There is a slight difference on the East Coast and a large difference on the West Coast
Interpreting with LOWERN• Latitude- further north the colder the average
temeperatures
• Ocean Currents- average temperatures will indicate whether coastal cities are on a warm or cold ocean current
• Elevation- the higher elevations usually have colder dryer climates
Interpreting with LOWERN• Relief- temperature is warmer and precipitation
is higher on the windward side of mountains
• Near Water- cities near large bodies of water will have a higher annual precipitation (above 1000mm) and a moderate temperature range
