Nandi County's highland climate is characterized by cool temperatures, abundant rainfall, and high altitude, creating a distinctive environment that shapes agriculture, human settlement, and notably, distance running excellence. Elevations across the county range from approximately 1,800 to 2,400 metres, with the Nandi Hills forming the primary topographic feature. Annual rainfall averages 1,500 to 2,000 millimetres in most areas, well distributed across two rainy seasons, making Nandi one of Kenya's more reliable rainfall regions.
Monthly temperatures remain relatively stable throughout the year, ranging from approximately 10 to 18 degrees Celsius, with minimal seasonal variation. The cool climate creates a perpetually green landscape with lush vegetation support. High humidity levels and frequent cloud cover characterize much of the year. This moderate climate has made the Nandi Hills a favoured destination for human settlement and has contributed to agricultural productivity. The climate provides excellent conditions for distance running training, with cool temperatures and altitude supporting physiological adaptations beneficial for endurance athletes. Climate change is beginning to alter rainfall patterns and temperature trends, with implications for agriculture and water availability. Conservation of water resources and adaptation of agricultural practices represent emerging climate challenges. The cool pleasant climate has also made Nandi Hills attractive for tourism and retirement settlement by people from lowland areas.
