Kenya Braces for Bitterly Cold Nights and Wet Weather

Kakuma, 11 August 2026
The Kenya Meteorological Department warns of sudden rainfall and temperatures plunging to a chilly 6°C in some regions, despite the country experiencing an ongoing dry spell.

A Dichotomy of Dry Spells and Sudden Downpours

The Kenya Meteorological Department (KMD) released an updated weather forecast on Tuesday, 11 August 2026, outlining a complex meteorological outlook for the week ahead [2][3][6]. While a significant portion of the country is currently experiencing a persistent dry spell, the meteorological authority has warned that select regions must prepare for sudden rainfall [2][3][4]. Specifically, eight counties—Bungoma, Trans Nzoia, Nakuru, Uasin Gishu, Elgeyo Marakwet, Kericho, Nyandarua, and Nyeri—are expected to receive rainfall between 11 August 2026 and 17 August 2026 [2][3][6]. This localized wet weather stands in stark contrast to the generally dry and sunny conditions dominating other parts of the nation [2][3][4].

An Analysis of Regional Precipitation Patterns

A closer look at the short-term forecast reveals highly variable precipitation patterns across the western and rift valley regions. West Pokot, Trans Nzoia, Uasin Gishu, and Nandi have been flagged for notable wet conditions, with West Pokot experiencing moderate afternoon showers that gradually ease into lighter rain [1][4][5]. Similarly, Kericho, Kakamega, and Bungoma are forecast to experience light afternoon showers [1][4][5]. For agricultural stakeholders and motorists, these sudden shifts underscore the reality that regional microclimates can experience sharp changes even during a broader dry season, making timely meteorological data essential for planning [5].

Plunging Temperatures and Escalating Health Risks

Alongside the rainfall warnings, the weatherman has issued alerts for unusually cold and cloudy conditions across several highland and central counties [1][4][5]. Nighttime temperatures are projected to drop below 10°C in areas such as Meru, Tharaka Nithi, Kirinyaga, Murang’a, Nyeri, Nyandarua, Laikipia, Nakuru, Narok, Kajiado, Trans Nzoia, and Taita Taveta [2][3]. The steepest temperature declines are expected in Nyandarua, where nighttime lows are forecast to plunge to a freezing 6°C [1][4][5]. In Nairobi, where daytime highs reach up to 26°C and nighttime lows drop to 12°C [1][4], residents must adapt to a diurnal temperature variation of 14°C, which significantly elevates the risk of respiratory infections [GPT].

Long-Term Climate Outlook and Disaster Preparedness

These immediate weather anomalies occur against a backdrop of worrying long-term climate projections. The Kenya Meteorological Service Authority has estimated an 81% probability of a strong El Niño developing in 2026, with a 97% likelihood that its associated effects will persist into early 2027 [2]. A national risk assessment conducted by the National Disaster Operations Centre (NDOC) has already identified potential threats across the region, citing heightened risks of flash floods, landslides, disease outbreaks, and infrastructure damage [2]. Consequently, the government has designated 18 counties as high-risk zones, urging local authorities to implement proactive mitigation strategies [2].

Shared Vulnerabilities in Turkana and Refugee Settlements

The impact of these shifting weather patterns is felt acutely in northwestern Kenya, particularly in Turkana County. While Turkana is forecast to remain largely sunny and dry with daytime temperatures exceeding 30°C [2][3], the broader regional instability in weather patterns directly threatens vulnerable populations [GPT]. For the host communities in Turkana and the refugee populations residing in the Kakuma and Kalobeyei settlements, sudden temperature drops and unexpected wet conditions demand immediate adjustments [GPT]. Securing fragile shelters against wind and rain is crucial to protecting children and elderly community members from the harsh elements, highlighting how environmental shocks transcend border and community lines [GPT].
