The "long rains" season occurs from March/April to May/June. The "short rains" season occurs from October to November/December. The rainfall is sometimes heavy and often falls in the afternoons and evenings. Climate change is altering the natural pattern of the rainfall period, causing an extension of the short rains, which has begat floods, and reducing the drought cycle from every ten years to annual events, producing strong droughts such as the 2008-09 Kenya Drought.
