Kenya enjoys an equatorial climate. In the low-lying areas, particularly along the coast, the climate is tropical, hot and humid. If your are traveling to Mombasa, there is no need to pack a blanket. The weather is quite hot even at night.Beach
On the Plateau and in the highlands the climate is more temperate. Western Kenya and most parts of Nyanza experience heavy tropical rain and have two rain seasons, the long rains from April to June and the short rains from October to November.
Nairobi has a more sober climate with none of the extremes. July and August are considered the coldest months in Nairobi and especially July, when it can get extremely cold.
Although Kenya runs through the equator, most of it is situated at 4,000 ft/1,200 m or higher, which tends to dissipate the heat. In higher regions, expect temperatures to be about 10 degrees F/5 degrees C cooler than in low-lying parts of the country. At the peak of Mt. Kenya, temperatures can fall below freezing and a sweater or jacket is recommended year-round
Once in a while Kenya experience the so called El nino rains. These are usually very heavy rains that wash away houses especially in the slums and plateau area.
Kenya’s warm climate is favourable for tourism during the drier season that is between September and March.
