Climate in different areas of Kenya is closely related to both altitude and proximity to water bodies. Over two-thirds of the country receive below 500 mm of rainfall per annum and only 11 % receives more than 1000 mm per year. The rainfall pattern is characterized by a relatively wet belt extending along the coast (c. 1000 mm) and another wet area covering Western Kenya to the East of Lake Victoria (c. 1400 mm). Higher rainfall is recorded on the upper slopes of Mt. Kenya (2000 mm) whereas low rainfall (255 mm) occurs in the North-eastern region. Generally, there are no appreciable changes in mean temperature throughout the year but there is considerable geographical and seasonal variation. Temperature patterns are closely linked to altitude, with the highest being recorded in the arid regions in the North-eastern region, with a mean annual of 34 °C and the lowest on top of mountains where night frost occurs above 3000 m (-2.2 DC).
