Kenyans are expected to experience colder mornings, foggy conditions and strong winds over the next three months, according to the latest June–July–August (JJA) 2026 seasonal forecast released by the Kenya Meteorological Department (KMD).
Kenya Met has also warned that temperatures are expected to remain warmer than average across much of the country.
The forecast shows that the June to August period, traditionally Kenya’s cool season, will be marked by varying weather conditions across different regions.
Rainfall is expected to be concentrated mainly in western Kenya, parts of the Rift Valley, north-western Kenya and the Coast.
Kenya Met Forecasts Cold Mornings, Fog in June-August Outlook
The forecast indicates that warmer-than-average temperatures are expected across the country during the JJA season, with a higher likelihood over the Highlands West of the Rift Valley, the Lake Victoria Basin, the Coast, and the north-western and north-eastern regions.
However, cool and cloudy conditions with occasional fog are expected in the Highlands East and West of the Rift Valley, parts of the Rift Valley, sections of the South-eastern Lowlands and parts of north-eastern Kenya, particularly Marsabit County, especially in the mornings and evenings.
Light rains, fog, and cloudy conditions are expected in the Highlands East of the Rift Valley, including Nairobi, some high-altitude areas of north-eastern Kenya, and parts of the South-eastern Lowlands.

Strong Winds Expected
The forecast also warns of strong winds over the Coast, South-eastern Kenya, North-eastern Kenya and North-western Kenya.
The winds may disrupt transport operations, affect marine activities and damage light structures in vulnerable areas.
Motorists have been advised to exercise caution in areas expected to experience fog and reduced visibility.
Rainfall Outlook
The meteorological department projects near-average to below-average rainfall in the Lake Victoria Basin, the Highlands West of the Rift Valley, the Rift Valley and north-western Kenya.
These areas are expected to experience intermittent dry spells throughout the season.
The Coastal region, including Mombasa, Kilifi, Kwale, Lamu and the Tana Delta, is expected to receive near-average to above-average rainfall, with occasional rainy episodes despite the cool season.
North-eastern Kenya, the South-eastern Lowlands and most parts of Turkana and Samburu are expected to remain largely sunny and dry.

Advisory to the Public
The Kenya Met has urged the public to take precautionary measures during the season.
Farmers are advised to plan agricultural activities carefully and make use of expected rainfall to support crop growth and pasture development.
Households and businesses are also encouraged to use water resources efficiently, particularly in areas expected to experience dry spells.
Motorists and air travelers have been cautioned that fog may reduce visibility on roads and at airports, especially in highland areas. Strong winds could also disrupt transport and infrastructure.
Kenya Met warned that cold conditions may increase respiratory illnesses such as flu and pneumonia, while dust and strong winds in dry regions may worsen respiratory problems among vulnerable groups.
The department further warns of possible localized flooding in low-lying areas of the Lake Victoria Basin and parts of the Coast. In western Kenya, residents have been urged to remain alert due to the risk of lightning strikes during rainfall.
Residents have also been advised to secure light structures and take precautions against cold-related illnesses as the country enters the peak of the cool season.
