The Kenya Meteorological Department has issued a warning for increased rainfall and isolated storms expected across several parts of the country between Tuesday, August 12, and Monday, August 18, 2025.
According to the weekly forecast, residents in the Central Highlands, Western and parts of the North-western region should brace for intensified rainfall, with some areas likely to experience localised thunderstorms.
“Intermittent cold and cloudy conditions may occur over parts of the Central Highlands, Western Kenya, South-eastern Lowlands and the Rift Valley,” Met added.
Additionally, temperature variations are expected across the country.
North-eastern and North-western regions may see daytime highs above 30°C, while night-time temperatures could fall below 10°C in parts of the Central Highlands, Central Rift Valley and areas near Mt Kilimanjaro.
The department also cautioned about strong southerly to south-easterly winds, expected to exceed 25 knots (12.86 m/s).
These are particularly along the Coast, Kenya’s territorial waters, and parts of the South-eastern Lowlands, North-eastern and North-western regions.

Daytime temperatures are expected to range between 28°C and 30°C, while night temperatures may dip to around 11°C.
