Baringo County's climate is characterized as semi-arid savanna with significant altitude variation, bimodal rainfall patterns, and substantial seasonal and inter-annual rainfall variability. The semi-arid climate creates challenges for pastoral and agricultural livelihoods requiring adaptive management strategies.
Rainfall Patterns
Baringo receives bimodal rainfall with long rains from March to May and short rains from October to November. Annual rainfall ranges from approximately 300 millimeters in the driest pastoral areas to 1,000 millimeters in elevated Tugen Hills areas.
Rainfall is highly variable both within years and between years, with periodic severe drought years creating water and forage scarcity affecting pastoral and wildlife populations.
Temperature and Elevation
Baringo spans significant elevation ranges from approximately 800 meters in the Rift Valley floor to 3,000 meters in the Tugen Hills. Temperature varies substantially with elevation, with lowland areas experiencing hot savanna conditions and highland areas having cooler temperate climates.
Seasonal Patterns
Dry seasons from January to February and June to September create water scarcity and forage limitations. Pastoral communities employ transhumance (seasonal livestock movement) to track available water and forage.
Rainy seasons trigger vegetation growth supporting livestock and wildlife populations.
Climate Variability and Drought
Severe droughts in 2000, 2011, and 2016-2017 caused significant livestock losses and humanitarian crises. Climate variability appears to be increasing in frequency and intensity.
Water Availability
Water represents the primary climate-related limiting factor. Lake Baringo, springs, water holes, and constructed boreholes provide water access, though availability varies seasonally and annually.
