The Kenya Meteorological Department has cautioned Kenyans to prepare for increased rainfall and above-normal temperatures throughout April 2025.
In its latest weather outlook, the department forecasts heightened rainfall across several regions, including Nairobi, the Lake Victoria Basin, and the Highlands West of the Rift Valley. These areas are expected to experience more rainfall than usual, with occasional storms anticipated.
According to the Director of Meteorological Services, David Gikungu, the country is entering the peak of the ‘Long Rains’ season, and most regions should expect near-to-above-average rainfall.
“We anticipate that areas such as the Lake Victoria Basin, the Rift Valley, and parts of the Highlands East and West of the Rift Valley will experience significant rainfall, with occasional storms,” Gikungu noted.
The forecast indicates that regions including the South-Eastern Lowlands, Northwestern, and parts of Northeastern Kenya will likely see increased rainfall, while the Coastal region and some parts of Northeastern Kenya may experience average rainfall levels.
Counties such as Siaya, Kisumu, Homa Bay, Migori, and Kisii in the Lake Victoria Basin are likely to experience above-normal rainfall. Similarly, areas like Turkana and Samburu in the Northwest are expected to receive occasional showers, with rainfall levels near or slightly above the long-term average.
In the Highlands East of the Rift Valley—including Nyeri, Kirinyaga, and Nairobi—above-normal rainfall is expected, accompanied by sporadic storms.
The expected rainfall is projected to benefit agriculture, particularly in the Highlands and South-Eastern Lowlands.
“The increased rains will support crop growth and improve pasture conditions in arid and semi-arid regions,” Gikungu stated. However, he warned that areas receiving heavy rainfall could face risks such as land degradation and soil erosion.
The department also highlighted the potential benefits for water availability, including improved hydropower generation and groundwater recharge for geothermal energy.
Despite the positive aspects of the rainfall, Gikungu cautioned that the heavy downpours could trigger flash floods, particularly in urban areas with poor drainage and regions near major rivers.
He urged the public to avoid walking, driving, or cycling through moving water to prevent accidents.
Other risks include landslides in high-risk zones and lightning strikes in counties such as Kisii and Kisumu.
The department also raised concerns about a possible rise in waterborne and vector-borne diseases due to stagnant water in areas experiencing heavy rainfall. Residents were encouraged to use treated mosquito nets and observe proper hygiene practices to minimize disease outbreaks.
The Meteorological Department urged motorists to exercise caution on wet roads, warning that slippery surfaces and reduced visibility could lead to accidents.
Additionally, Kenyans were advised to practice rainwater harvesting to take advantage of the increased rainfall while staying alert to potential weather-related disruptions.
“While the rains will be beneficial in many ways, the public must remain cautious of the risks associated with flash floods, landslides, and storm hazards,” Gikungu emphasized.
The department encouraged citizens to stay informed and follow updates from official weather forecasts to ensure their safety during this rainy period.
