Read a climate graph
The dataset is invented for graph practice. Temperature is monthly mean air temperature; rainfall is monthly total.
Temperature range?
Draw rainfall bars and a temperature line. If sharing one chart, clearly label separate axes with different units; do not compare bar and line heights as though they measure the same thing.
📊 Calculate
Annual rainfall: 625 mm. Temperature range: 20 − 6 = 14°C. Warmest months: July and August. Wettest month: December.
Describe the seasonal pattern using at least two numbers. The data suggests drier warmer months, but one fictional year cannot establish a real region’s climate or identify its location. A climate description normally uses observations over many years.
✅ Check your understanding
Wettest month?
Can you locate this place exactly from the table?
✅ Compare seasons before checking
Using the supplied table, total June–August rainfall and December–February rainfall. How many millimetres wetter is the second three-month period? Explain why adding monthly temperatures is not the equivalent of annual rainfall.
🔑 Worked answer
June–August: 30 + 20 + 25 = 75 mm. December–February: 85 + 80 + 60 = 225 mm, 150 mm wetter. Rainfall totals accumulate; monthly mean temperatures need an appropriate average, not a sum described as annual temperature.
