Kenyans should brace for a wetter-than-usual April as the Kenya Meteorological Department signals a steady increase in rainfall across much of the country. While the first half of the month may bring relatively moderate showers, conditions are expected to intensify as the weeks progress, raising concerns over flooding in vulnerable areas.
The long rains season, which typically defines Kenya’s agricultural and economic cycles, is now entering a critical phase. Weather experts warn that the evolving patterns could disrupt daily life, particularly in urban centres and flood-prone regions.
Counties on alert as storms intensify
Several regions are expected to experience widespread rainfall accompanied by occasional storms. Areas within the Lake Victoria Basin and parts of the Rift Valley are likely to see persistent showers, with border regions near Uganda and South Sudan facing heightened storm activity.
Counties east of the Rift Valley—including Nairobi, Kiambu County, Nyandarua County, Laikipia County, and Embu County—are expected to receive above-average rainfall. These areas may also experience colder daytime temperatures due to increased cloud cover and storm activity.
Meanwhile, northeastern counties such as Marsabit County, Wajir County, and Mandera County are projected to receive above-average rainfall, though some localized areas could still experience near-to-below-normal conditions.
In contrast, the coastal region may record below-average rainfall, offering a different weather pattern compared to the rest of the country.
What’s driving the heavy rains?
According to meteorologists, the current rainfall patterns are largely influenced by the movement of the Intertropical Convergence Zone (ITCZ). This seasonal system plays a major role in shaping East Africa’s climate.
As the ITCZ shifts northward, it pulls in moist air masses from both the Indian Ocean and the Congo Basin. When these air systems converge over Kenya’s highlands, they create the perfect conditions for sustained rainfall, thunderstorms, and fluctuating temperatures.
This natural cycle is typical during the long rains season, but variations in intensity can significantly affect agriculture, infrastructure, and water systems.
Flood risks and infrastructure concerns grow
With heavy rains already experienced in March, authorities are warning that April could bring renewed flooding in several parts of the country. Water resource managers have been urged to closely monitor river levels and ensure drainage systems remain clear.
Urban areas, especially Nairobi, remain particularly vulnerable due to blocked drainage systems and rapid surface runoff. Past incidents have shown how quickly roads can become impassable, disrupting transport and economic activity.
Road agencies have also been placed on high alert, as continued rainfall could damage infrastructure, trigger landslides in highland areas, and increase the risk of accidents.
Farmers advised to prepare early
The rains, while beneficial for agriculture, come with challenges that require careful management. Farmers in high-rainfall regions have been advised to improve field drainage, unclog furrows, and avoid activities that compact already saturated soils.
Regions across western Kenya, Nyanza, Central, and parts of the Rift Valley are expected to receive near-average to above-average rainfall—conditions that can support crop growth if managed properly.
However, excessive moisture can also lead to waterlogging, crop diseases, and reduced yields if preventive measures are not taken in time.
Temperature patterns to shift nationwide
Alongside the rainfall, temperatures across the country are expected to vary. Most regions will experience warm but wet conditions, with daytime temperatures ranging between 20°C and 32°C.
Highland areas will remain cooler due to elevation and cloud cover, while coastal and northeastern regions are likely to record higher temperatures. Nighttime temperatures will also differ, with cooler nights in the highlands and warmer conditions along the coast.
A month to stay alert
As April unfolds, the combination of heavy rains, potential flooding, and shifting temperatures will require heightened awareness from both authorities and the public.
The forecast serves as a reminder of the importance of preparedness—from clearing drainage systems to monitoring weather updates and taking precautions in flood-prone areas.
With the long rains expected to peak in the coming weeks, Kenyans are being urged to remain vigilant and adapt to the changing weather conditions to minimize risks and disruptions.
