Kenya is a warm, dry country with seasonal rainfall. Rain falls mainly in two seasons: the first between March and May – the long rains – as a result of the south-easterly monsoon winds; the second in October/December. The Coast tends to be humid and hot.

The central highlands receive the most rainfall and tend to be cool, due to the high altitude. The Lake Victoria basin is wetter, owing to the moist westerly winds originating in the Atlantic and Congo Basin.

To the north and north-east, it is extremely dry and hot, with daytime temperatures exceeding 34 degrees. The Suguta Valley in northern Kenya is reputed to be one of the hottest places on earth.

 

Mount Kenya is glaciated, with a snow-cap all year round. Frost occurs in most areas in Kenya which are above 2,500m.
