Kenya's Meteorological Department has warned farmers that April rains will be significantly suppressed in the first two weeks before improving later. Farmers risk crop failure if they plant too early this month, according to the department's Monthly Agrometeorological Bulletin for April 2026, released on April 4. The agency advises aligning planting with the improving rains.
The Kenya Meteorological Department issued the warning in its Monthly Agrometeorological Bulletin for April 2026, released on April 4. “April 2026 is expected to mark the peak of the long rains season, though rainfall will be slightly depressed during the first half of the month and enhanced towards the end,” the department stated.
Near-average rainfall is expected in counties including Nyeri, Kirinyaga, Murang'a, Nyandarua, Kiambu, Meru, Embu, Tharaka Nithi, Nairobi, Laikipia, Busia, Migori, Kisumu, Siaya, and Homa Bay, offering prospects for good yields in high-potential areas once rains intensify. Counties such as Machakos, Kitui, Makueni, Kajiado, Taita-Taveta, Mombasa, Kwale, Kilifi, Tana River, and Lamu face lower soil moisture, requiring water harvesting and conservation.
Soil moisture will be moderate early in April but increase steadily, with waterlogging risks in the Highlands, Lake Victoria Basin, and Rift Valley. The department warns that rising humidity could trigger pest and fungal disease outbreaks, urging regular field scouting.
“Farmers should align planting with the improving rains, weed crops, ensure good drainage in wetter areas, and practice water conservation in drier regions,” Kenya Met advised. Areas flooded in March remain at high alert for renewed flooding from late-April downpours. The department urges farmers nationwide to use short-term forecasts for daily decisions.
