Nairobi residents have noted unusually high temperatures, but the Kenya Meteorological Department has assured there is no heat wave. In a statement on February 1, 2026, it explained that current conditions are seasonal and below the required threshold. No heat wave alerts have been issued anywhere in the country.
Nairobi residents have been experiencing unusually high temperatures, raising concerns about a possible heat wave. The Kenya Meteorological Department (KMD) issued a statement on Sunday, February 1, 2026, clarifying the phenomenon in the Kenyan context.
According to KMD, a heat wave in Kenya is defined as three or more consecutive days of extremely high daytime temperatures exceeding locally determined thresholds, based on historical records and health data. In Nairobi, the threshold is a daily maximum of 32°C or higher for three days. Kisumu's is 37°C, and Mombasa's is 36°C.
However, recent data shows average daytime temperatures of 28-29°C, which is typical for the season and below the 32°C mark. Thus, Nairobi is not undergoing a heat wave, and no alerts have been issued anywhere.
If a heat wave occurred, daily activities like outdoor work and commuting would become more challenging. Vulnerable groups—children, the elderly, pregnant women, and those with chronic illnesses—would face risks of heat exhaustion, dehydration, dizziness, fatigue, nausea, and headaches. In severe cases, heatstroke could result, straining the heart and lungs, especially for those with asthma, COPD, or heart disease.
Globally, countries like parts of Europe experienced over 40°C in 2023, leading to several heat-related deaths. In Kenya, northern counties such as Turkana see higher temperatures above 38°C, but Nairobi benefits from its cooler highland climate.
