Subtopic: Climatic Regions in Eastern Africa (age 11)

In Eastern Africa (including Kenya), the climate changes a lot from place to place. Different climatic regions affect how people live, the plants and animals that grow there, and the buildings people make. Below are the main climatic regions found in Eastern Africa and examples from Kenya.

Main Climatic Regions (quick view)

Equatorial / Rainforest πŸŒ³β˜”
- Very wet and warm all year.
- Found in parts of western Kenya and nearby countries (e.g., Kakamega area).
- Vegetation: thick forests.
Tropical Wet & Dry / Savanna 🌀️🌾
- Rainy season and dry season. Warm all year.
- Common in central and south-west Kenya (Masai Mara, parts of Rift Valley).
- Vegetation: grassland with scattered trees.
Semi-arid πŸŒ€οΈπŸ’§
- Little rain, long dry spells, some short rains.
- Found in parts of eastern and northern Kenya (e.g., Garissa outskirts).
- Vegetation: shrubs and sparse grass.
Arid / Desert β˜€οΈπŸœοΈ
- Very little rain and very dry.
- Found in far north-west and north-east Kenya (Turkana, northern parts).
- Vegetation: very sparse; adapted desert plants.
Highlands / Mountain (Cool) πŸ”οΈβ„οΈ
- Cooler temperatures and more rain than lowlands.
- Found in central Kenya (Mount Kenya, Nyeri, Nyandarua, Aberdares).
- Vegetation: forests, tea and coffee farms at higher levels.
Coastal (Hot & Humid) πŸ–οΈπŸŒ΄
- Hot, humid, with seasonal rains and sea breezes.
- Found along Kenya’s coast (Mombasa, Kilifi, Lamu).
- Vegetation: coconut palms, mangroves near the shore.

How climate affects people and the built environment

  • Houses: In hot coastal places people build houses with wide eaves, open windows and raised floors for better airflow. In highlands people build thick-walled homes to keep warmth.
  • Farming: Rainy areas grow tea, coffee, bananas and maize. Dry areas keep livestock (camels, goats) or grow drought-resistant crops (sorghum, millet).
  • Water supply: In arid and semi-arid areas communities dig boreholes or store rainwater because rainfall is low and unreliable.
  • Roads and buildings: Heavy rains can wash away roads in some places; builders add drains and stronger foundations.
  • Clothing and daily life: People wear light clothes in hot places and warmer clothes in cool highlands. Festivals, schools and work follow seasons (planting, harvesting).

Examples from Kenya (easy to remember)

Mombasa (Coast): Hot and humid, lots of palms, tourism and fishing.

Mount Kenya region (Highlands): Cool, rain, farms growing tea and potatoes.

Masai Mara (Savanna): Wet and dry seasons, grassland, wildlife and pastoral communities.

Turkana (Northwest): Arid, very dry, pastoralists keep camels and goats.

Class activity (5–10 minutes)

  1. Look at a map of Kenya. Shade areas you think are dry and areas that are wet.
  2. Choose one region. Draw a simple house that fits that climate (e.g., open windows for coast, thick walls for highlands).
  3. List two crops or animals you would expect there and explain why.

Key words

Climate, rainfall, temperature, arid, semi-arid, savanna, highlands, coastal, built environment, adaptation.

Did you know? Parts of Kenya can have both very hot dry areas and cool wet mountains within a few hundred kilometres. That is why people in Kenya have many different ways of living and building homes.

Quick quiz (answers at the end)

  1. Name one crop that grows well in the highlands of Kenya.
  2. Which climate has very little rain and is found in Turkana?
  3. Give one way people adapt their houses on the coast.
Answers:
  1. Tea, potatoes or coffee (example: tea on the highlands).
  2. Arid (desert) climate.
  3. Build houses with wide eaves and large windows for airflow, or build on stilts to reduce humidity effects.

Use these notes to help you understand how climate shapes life in Eastern Africa and in Kenya. Teachers can use the class activity to make a short practical lesson.
