NAIROBI — Kenya’s unusually cool and dry weather is offering national and county governments a narrow opportunity to strengthen flood preparedness before forecasters expect wetter conditions to return later this year.
Regional climate experts say most parts of the country are likely to remain drier than normal through September. However, climate models monitored by the IGAD Climate Prediction and Applications Centre (ICPAC) indicate that rainfall could become significantly heavier during the October-December short rains if the developing El Niño combines with a positive Indian Ocean Dipole.

The forecast has renewed concerns among disaster management agencies because many drainage systems, roads and bridges damaged during the March-May rainy season remain under repair.
The Kenya Meteorological Department’s July outlook shows that while much of Kenya will experience generally dry and sunny conditions, Nairobi and the Central Highlands are expected to remain cool and cloudy with occasional light rain. Coastal counties are forecast to receive relatively higher rainfall than the rest of the country, while northern Kenya continues to face hot, dry and windy conditions.
“High chances of drier than normal conditions are expected over most of the region through September. Enhanced rainfall is then expected over many equatorial areas during the October-December season,” ICPAC said in its latest regional outlook.
Flood lessons remain fresh
The warning comes only months after widespread flooding caused extensive damage across Kenya, exposing weaknesses in drainage infrastructure, transport corridors and informal settlements located near rivers.
Floodwaters disrupted transport, damaged homes and public infrastructure, and highlighted the vulnerability of rapidly growing urban centres such as Nairobi, Kisumu, Mombasa and Nakuru.
Emergency planners say the current dry spell provides valuable time to repair blocked drainage channels, reinforce riverbanks and clear storm-water systems before the onset of the short rains.
Several county governments have already begun inspections of flood-prone neighbourhoods while coordinating with road agencies responsible for repairing damaged bridges, culverts and highways.
Nairobi braces for another rainy season
Nairobi remains among the cities under closest observation because of its history of flash floods along the Nairobi River corridor and densely populated informal settlements.
City engineers have continued drainage improvement works in areas identified as flood hotspots following the March-May rains. However, officials acknowledge that many long-term infrastructure projects cannot be completed before October.
Urban planners warn that if heavy rainfall coincides with blocked drainage systems, transport disruptions and localized flooding could quickly return.
Why El Niño matters
El Niño develops when sea surface temperatures in the central and eastern equatorial Pacific become warmer than average.
Although the phenomenon affects weather differently across the world, East Africa often experiences above-average rainfall during the October-December short rains when El Niño occurs alongside a positive Indian Ocean Dipole.
Meteorologists caution that no single climate system determines Kenya’s weather on its own, but the combination of global ocean temperatures and regional atmospheric conditions increases the likelihood of wetter conditions later this year.
What Kenyans should do
Disaster experts advise residents to use the remaining dry months to prepare for possible flooding by:
- Following official weather updates issued by the Kenya Meteorological Department.
- Avoiding construction or dumping waste in drainage channels.
- Clearing blocked estate drains and culverts.
- Identifying alternative routes around flood-prone roads.
- Never attempting to drive or walk through fast-moving floodwaters.
Governments urged to act now
Climate specialists stress that the present weather should not be mistaken for a reduced flood risk.
Instead, they describe the coming weeks as a critical preparedness period that could determine how well counties withstand the next rainy season.
If infrastructure repairs, drainage maintenance and emergency planning are completed before October, authorities believe Kenya will be better positioned to reduce the impact of any enhanced rainfall forecast for the end of the year.
