Weatherman Warns of Strong Winds, Dense Fog as Dry Spell Dominates August

The Kenya Meteorological Department (KMD) has released its August 2026 weather forecast, saying most parts of the country will experience sunny and generally dry conditions.

Despite August being part of Kenya’s cold season, Kenya Met states that temperatures are expected to be warmer than usual across the country.

In its August 2026 monthly weather outlook released on Monday, August 3, the Kenya Meteorological Department said that while much of the country will remain dry, some regions will continue to experience morning drizzle, fog, and isolated rainfall.

Kenya Met Says Nairobi, Central Highlands to Remain Cool and Foggy

According to the weatherman, intermittent cool and cloudy conditions, accompanied by light morning rain, drizzle, and fog, are expected over Nairobi and the Central Highlands, including Kiambu, Nyeri, Murang’a, and Meru counties. The conditions could occasionally extend into early September.

Meanwhile, northwestern and northern counties such as Turkana, Samburu and Marsabit are expected to remain largely sunny and dry during the month.

The Lake Victoria Basin and the Coast, including Kisumu, Kakamega, Mombasa and Kwale counties, are likely to receive near-average to below-average rainfall, although a few areas may experience isolated heavy downpours.

Despite the generally dry conditions, KMD said mean temperatures across the country are expected to be above normal throughout August.

Night-time temperatures in Nairobi and the Highlands could fall to as low as 5°C, while daytime temperatures in northeastern counties such as Mandera, Garissa and Wajir are expected to rise to 37°C.

Strong Winds Could Disrupt Transport

The Department also warned of strong southerly to south-easterly winds exceeding 25 knots (12.86 metres per second) over parts of the Coast, Northeastern Kenya and the Rift Valley.

The strong winds could disrupt marine transport and cause damage to infrastructure, including roofs and power lines.

Motorists travelling in Nairobi and the Central Highlands have been advised to exercise caution as fog and morning drizzles are expected to reduce visibility, increasing the risk of road accidents.

The Department further warned that dense fog could occasionally disrupt flight operations at Jomo Kenyatta International Airport and Wilson Airport.

Residents in the Lake Victoria Basin and western Kenya have also been urged to remain alert for possible lightning strikes during isolated storms.

Health, Agriculture and Water Supply Concerns

KMD said cooler conditions in counties such as Nairobi and Nyandarua may lead to an increase in respiratory illnesses, including asthma, pneumonia and influenza.

In arid and semi-arid areas, strong winds are expected to raise dust levels, potentially worsening eye infections and respiratory conditions.

The forecast indicates that the expected dry weather will favour harvesting activities in the Rift Valley and parts of western Kenya. However, concerns remain over food and pasture shortages following previous dry spells.

The Department also warned that reduced rainfall over the Mt. Kenya catchment could lower water levels in hydro-electric dams, while water availability is expected to decline further across Arid and Semi-Arid Lands (ASALs).
