Although Kenya lies on both sides of the Equator, many of its climatic zones are typical of the tropics, with the country's geographical features exerting considerable influence on weather patterns. Kenya's climate is best described as monsoonal meaning to have monthly mean temperatures above 18 °C in every month of the year and feature wet and dry seasons.
Even during the rainy season there is sunshine almost every day. The Equator passes through Kenya thus making daylight hours not vary much year round from 6.30am to 6.30pm.
Warm dry season runs from January to late March this season and has light rainfall. The average number of rain days in January and February is however only 5mm per month. The long rainy season runs from late March to early June. During this season, rainfall amounts are high but it is frequently warm and sunny for the better part of the day and often may not rain at all for two or three days at a time. The cool dry season runs from mid-June to early October as the south-east monsoon sets in, the rains give way to the driest season. A short rainy season runs from mid-October to mid-December.
The best filming times are from January to March or mid-May to September, although filming may be carried out throughout the year as there are no distinctively marked winters. Also note that the perfect film season for wildlife lovers is in January and February, when the weather is hottest and driest. At this time, the animals in the wildlife parks tend to congregate more around the watercourses, making them easier to spot. From June to October, the Annual wildebeest migration takes place with thousands of animals streaming into the Masai Mara National Reserve from the Serengeti.
