Several parts of the country are expected to receive rainfall this week as the October–December (OND) 2026 Short Rains season gets underway.
The Kenya Meteorological Department forecasts light to moderate rainfall in parts of Nairobi, Nakuru, Baringo, Bomet, Bungoma, Busia, Elgeyo Marakwet, Embu, Garissa, Homa Bay, Kajiado, Kakamega, Kericho, Kiambu, Kilifi, Kirinyaga, Kisii, Kisumu, Kitui and Kwale.

Isolated thunderstorms are also expected in parts of Mandera, Wajir, Marsabit, Tana River and Kilifi counties, with the storms potentially triggering flash floods. Residents in areas prone to flooding are advised to remain alert and take necessary precautions as the rains continue.
What the OND season means
The October–December rains, commonly known as the Short Rains, are one of Kenya's two main rainfall seasons and are critical for agriculture in the eastern, coastal and north-eastern regions. The season typically peaks in November and plays a key role in replenishing water sources, supporting pasture regeneration and enabling planting in counties that receive little rain during the March–April long rains.
The Meteorological Department's seasonal outlook guides farmers, county governments and disaster-management agencies in planning. A well-performing short-rains season can ease pressure on food prices and water supply; a poor one often deepens drought conditions in arid counties.
Flood risk and safety
While the rains are largely welcome, heavy downpours in low-lying and urban areas frequently cause flash floods, blocked drainage and disrupted transport. Residents in flood-prone areas are advised to avoid crossing swollen rivers and streams, secure loose roofing materials, and stay updated on forecasts from the Kenya Meteorological Department.
County governments in high-risk areas typically activate emergency response teams during the season, and the Kenya Red Cross Society maintains flood-response preparedness in historically affected regions.
