The climate in Kenya is predominantly tropical although the geography of Kenya is varied. Kenya remains warm all through the year. Droughts are common in Kenya periodically mainly due tot the delays in the start of the rainy seasons. Climate in Kenya has proved to have a profound effect on settlement patterns as evident from the concentration of settlement in the wettest areas of Kenya.

Kenya is hot and humid at the coast, temperate inland and very dry in the north and northeast parts of the country. The average annual temperature for the coastal town of Mombasa (altitude 17 metres) is 30.30 Celsius maximum and 22.40 Celsius minimum, the capital city, Nairobi (altitude 1,661 metres) 25.20 Celsius maximum and 13.60 Celsius minimum, Eldoret (altitude 3,085) 23.60 Celsius maximum and 9.50 Celsius minimum, Lodwar (altitude) 506 metres) and the drier north plain lands. 34.80 Celsius maximum and 23.70 Celsius minimum. Kenya gets abundant sunshine all the year round. However, nights and early mornings are slightly cold.

Most parts of Kenya get seasonal rainfall. The coast, eastern plateaus, and lake basin experience two rainy seasons: the "long rains" extends roughly from March to June, and the "short rains" lasts from approximately October to December. The highlands of western Kenya have a single rainy season, lasting from March to September. Between June and September, the annual migration of wildlife between Serengeti National Park in Tanzania and Maasai Mara National Park in Kenya takes place This spectacular moving scene of the migration of almost two million wildbeasts and other species have always been the delight of tourists and filmmakers.
