Being on the Equator Kenya has a year round tourist season, it also has two rainy seasons; the long rains (April to June) and short rains (October to December). The Summer is in February and March and strangely winter is in July and August as the sun approaches the equinox.
The traditional time for going on safari is from January to March, before the rains start but you can usually get around at all times of year. The Great Migration generally comes to the Mara from the Serengeti between July and October depending on rains.
Kenya’s diverse geography means that temperature, rainfall and humidity vary widely, however, there are effectively four distinct zones:
The plateau of western Kenya has rainfall throughout the year, the highest volumes being in April and lowest in January. Temperatures range from a minimum of 14°C to a maximum of 36°C throughout the year.
Rift Valley and Central Highlands
The temperate Rift Valley and Central Highlands has rainfall in essentially two seasons – March to the beginning of June (the ‘long rains’) and October to the end of November (the ‘short rains’). Temperatures vary from 10°C to 28°C.
Northern and Eastern Kenya
The semi-arid bushlands of northern and eastern Kenya have rainfall in the form of violent storms, with July being the driest month, and November the wettest. Temperatures vary from up to 40°C during the day to less than 20°C at night.
The consistently humid coast region has rainfall that is dependent on the monsoon which blows from the north-east from October to April and from the south-west for the rest of the year. Temperatures vary little during the year, ranging from 22°C to 30°C.
