Climate graphs
Bar charts and line graphs can be combined. Climate graphs are an example of this.
The x-axis shows the months of the year and there are two y-axes to show average temperature and total rainfall (also known as precipitation). The temperature is shown as a line and the rainfall as bars.
When describing a climate graph, you should include: -
- The highest and lowest rainfall figures and the month they occurred.
- The total annual rainfall.
- The average rainfall.
- The highest and lowest temperature figures and the month they occurred.
- The temperature range.
- The average yearly temperature.
Question
Describe the temperature and climate for the region displayed in the graph.
Hints
- note the highest/lowest for each month
- include values for temperature and precipitation
- include range for temperature (highest subtract the lowest)
- note any trends, eg does it rain all year?
- are any month at risk of flooding?
The highest precipitation takes place in March with a value or 310mm.
The lowest precipitation is in August with 60mm.
Precipitation takes place all 12 months of the year.
January to May could be at risk of flooding, as rainfall is over 250mm for those months.
The highest temperature is in August, September and October, with approx. 30 °C.
The lowest temperature in January and February is 26 °C . This leads to a small range of temperature across the year of only 4 °C .
