The rainy seasons in Kenya are April to June and October to early December. The coast is hot and humid all year round but tempered by strong onshore breezes, the lowlands are hot and dry and the highlands (including Nairobi) are more temperate and cool at night.
Situated at a high altitude, Nairobi has a moderate climate. The summer months are sunny and warm without blistering temperatures, while winters are mild to cool, with very chilly evenings. Rainfall is also moderate, the wettest part of the year being late summer to autumn, when cloudy, drizzly days are common.
