The Kenya Meteorological Department has forecast heavy rainfall in Nairobi and other regions between Tuesday, September 16, and Monday, September 22, 2025
The other regions include the Lake Victoria Basin, Rift Valley, Western Kenya, the Coast and parts of the Central Highlands.
In its weekly outlook released on Tuesday, the department said most of the country will remain sunny and dry, but several regions should brace for significant rainfall.
Residents in the highlighted areas have been urged to remain alert to possible weather-related disruptions.
The forecast also warns of strong southerly to south-easterly winds exceeding 25 knots (12.86 m/s) across the Coast and Kenya’s territorial waters, as well as in the south-eastern lowlands, north-eastern and north-western Kenya.
These conditions could pose risks for marine activities, transport, and infrastructure.

Daytime highs above 30°C will be experienced in the Coast, North-eastern and North-western regions.
In contrast, night-time lows below 10°C are likely in sections of the Central Highlands, the Central Rift Valley and the Mt Kilimanjaro region.
