The coastal areas are tropical, but tempered by monsoon winds. The lowlands are hot but mainly dry, while the highlands are more temperate with four seasons. Nairobi has a very pleasant climate throughout the year due to its altitude. Near Lake Victoria, the temperatures are much higher and rainfall can be heavy.

Lightweight cottons and linens with rainwear are advised for the coast and lakeside. Warmer clothing is needed in June and July and for the cooler mornings on the coast. Lightweights are needed for much of the year in the highlands. Rainwear is advisable between March and June and October and December.

Kenya shares borders with Ethiopia in the north, Sudan in the northwest, Uganda in the west, Tanzania in the south and Somalia in the northeast. To the east lies the Indian Ocean. The country is divided into four regions: the arid deserts of the north; the savannah lands of the south; the fertile lowlands along the coast and around the shores of Lake Victoria; and highlands in the west, where the capital Nairobi is situated. Northwest of Nairobi runs the Rift Valley, containing the town of Nakuru and Aberdare National Park, overlooked by Mount Kenya (5200m/17,000ft), which also has a national park. In the far northwest is Lake Turkana (formerly Lake Rudolph). Kenya is a multicultural society; in the north live Somalis and the nomadic Hamitic peoples (Rendille, Samburu and Turkana), in the south and eastern lowlands are Kamba and Masai and the Luo live around Lake Victoria. The largest group is the Kikuyu who live in the central highlands and have traditionally been dominant in commerce and politics, although this is now changing. There are many other smaller groups and, although Kenya emphasises nationalism, tribal and cultural identity is a factor. A small European settler population remains in the highlands, involved in farming and commerce.
