Climate Data Historical

Kenya's climate ranges from tropical (along the coast) to arid (in the mountain regions). Kenya's climate is impacted by the El Nino Southern Oscillation (ENSO), as well as the movement of the Inter-Tropical Convergence Zone (ITCZ). The rainy season in Kenya usually begins in March and decreases in May to June. The second wet season begins around September/October and shows a decreasing trend in December. The windiest time of the year occurs during the southeast monsoon, which extends from May to September.

Temperature

  • Since 1960, Kenya’s mean annual temperature has increased by 1.0°C, at an average rate of 0.21°C per decade.
  • The rate of increase has been most rapid in March to May (0.29°C per decade) and slowest in June to September (0.19°C per decade).

Precipitation

  • Observations of rainfall over Kenya since 1960 do not show statistically significant trends, as trends in the extreme indices based on daily rainfall data are mixed.
