Overview

Kenya is located in east Africa, at latitudes of 6°S to 6°N. Located on the Indian Ocean, its climate is tropical, but moderated by diverse topography in the west. Kenya’s topography rises from the coastal plains to the eastern edge of the East African Plateau, and the Great Rift Valley. The central highland regions are substantially cooler than the coast, with the coolest (highest altitude) regions at 15°C compared with 29°C at the coast. Temperatures vary little throughout the year, but drop by around 2 degree in the coolest season. Seasonal rainfall in Kenya is driven mainly by the migration of the Inter‐Tropical Convergence Zone (ITCZ), relatively narrow belt of very low pressure and heavy precipitation that forms near the earth’s equator. The exact position of the ITCZ changes over the course of the year, migrating southwards through Kenya in October to December, and returning northwards in March, April and May. This causes Kenya to experience two distinct wet periods – the ‘short’ rains in October to December and the ‘long’ rains in March to May. The amount of rainfall received in these seasons is generally 50‐200mm per month but varies greatly, exceeding 300mm per month in some localities.
