How to Describe the Climate of a Place Using Climate Graphs

If you complete this lesson, you'll be able to look at a climate graph and clearly describe the climate of a place—like whether it's hot, cold, wet, or dry throughout the year.

What Is a Climate Graph?

A climate graph (or climograph) shows the average temperature and rainfall (precipitation) for each month of the year in one place. Usually, bars show rainfall and a line shows temperature.

Why Do Climate Graphs Matter?

Climate graphs help us quickly understand the weather patterns of a city or region. They're used in geography, travel, farming, and even choosing what clothes to pack for a trip.

How to Read a Climate Graph

1. Look at the x-axis (bottom): This shows the months (January to December).
2. Look at the left y-axis: This usually shows rainfall (in mm). The bars go up higher for wetter months.
3. Look at the right y-axis: This shows temperature (in °C). The line goes up for warmer months.

Worked Example: Describing a Climate Graph

Imagine a climate graph for Cairo, Egypt:

• Rainfall bars are very low all year (0–5 mm).
• The temperature line is high (around 20°C in winter, up to 35°C in summer).

How to describe it:

• "Cairo has a hot and very dry climate. Temperatures are high all year, peaking in summer. Rainfall is extremely low throughout the year."

Common Mistakes and How to Avoid Them

• Mixing up temperature and rainfall: Remember, bars are for rainfall, the line is for temperature.
• Describing only one part: Always mention both temperature and rainfall.
• Forgetting to mention when: Say which months are hottest, coldest, wettest, and driest.

Real-Life Application

Farmers use climate graphs to decide what crops to plant. Tourists check them to plan trips during pleasant weather.

Try It Yourself

Look at a climate graph for London:

• Rainfall: 40–60 mm every month
• Temperature: 4°C in January, 18°C in July

Describe the climate in one sentence.

Takeaway

If you can describe a climate graph, you can quickly tell someone what the weather is like in any part of the world. You'll use this skill in geography class, travel planning, and understanding news about climate.
