The Kenya Meteorological Department has forecast rainfall in parts of several counties between September 15 and 21, 2026. This forecast is significant as it comes at a time when many regions are preparing for the transition into the rainy season, which is crucial for agricultural activities and water supply.
According to the department’s weekly forecast, rainfall is expected at different times of the day in parts of Nairobi, Mombasa, Kilifi, Kwale, Kisumu, Nakuru, Kakamega, Kiambu, Meru, Nyeri and other counties. The predicted rainfall is likely to vary in intensity and duration, impacting various sectors including agriculture, transportation, and daily activities of residents in these areas.
Coastal counties, including Mombasa, Kwale, Kilifi, Tana River and Lamu, are expected to experience morning showers in some areas during the forecast period. These morning showers could provide much-needed moisture for crops and replenish local water sources, which are vital for both domestic and agricultural use.
Morning rainfall is also expected in parts of Nairobi, Kiambu, Murang’a, Nyeri and Meru. This early precipitation may lead to a cooler atmosphere, benefiting those engaged in outdoor activities and work.
In the afternoon, showers and thunderstorms are forecast in parts of Western Kenya, the Rift Valley and the Central region. Some areas of Nairobi and other counties may also receive afternoon showers. The afternoon rains could disrupt travel and outdoor events, prompting residents to plan accordingly.
The forecast further indicates that some areas of Nairobi, Mombasa, Nakuru, Nyeri and Meru may experience rainfall at night. Nighttime rainfall can have various effects, including improved soil moisture levels for farmers preparing for planting, but it may also pose challenges for nighttime transport and safety.
The Meteorological Department cautioned that the forecast does not mean all areas within the named counties will receive rainfall, noting that the weather conditions will affect specific locations. This variability underscores the importance of localized weather monitoring, as conditions can differ significantly even within short distances.
Members of the public have been advised to continue monitoring weather updates and take appropriate precautions to protect lives and property during the forecast period. This advice is particularly relevant for those living in areas prone to flooding or landslides, as well as for farmers who need to safeguard their crops from potential adverse weather conditions.
