Kericho's distinctive microclimate represents one of the region's most important environmental features, characterized by high altitude, reliable abundant rainfall, and cool temperatures. Elevations across the county range from approximately 1,500 to 2,300 metres, with higher areas featuring cooler temperatures year-round. The annual rainfall pattern brings almost daily afternoon thunderstorms during rainy seasons, maintaining perpetually moist conditions that support lush vegetation and tea plant growth.
Monthly temperatures remain relatively stable throughout the year, ranging from approximately 12 to 20 degrees Celsius, with minimal seasonal variation compared to lowland regions. The cool, wet climate minimizes certain agricultural pests and diseases while supporting continuous tea plant growth. High humidity levels and frequent cloud cover characterize much of the year. This microclimate creates a distinctive environment that shapes human settlement patterns, agricultural practices, and even social activities. The cool temperatures have made Kericho a favoured destination for residential settlement, with many people choosing to retire to the region's pleasant climate. Climate change has begun altering this microclimate, with impacts on rainfall patterns and temperature trends affecting agriculture and water resources.
