Skies are clear, cloudless and visibility is only hindered by sandstorms, which are a common occurrence. Temperatures of over 32 C are uncommon except on the coast or at places inland below an elevation of about 4000 feet. But markable seasons are experienced. They are also connected with the main air currents and trade winds. Two rainy seasons are experienced in Kenya with the long rains running from April to October and short rains from November to March.
Rainy seasons appear to show an increase in maximum cloud counts.
Sunshine is measured in hours per day and the longest hours of sunshine are in the drier parts. It is rare in Kenya at the altitudes commonly inhabited, although mountain peaks and the tops of ranges may be hidden in cloud. Hailstorms are an important form of precipitation in Western Kenya and also in the Lake Victoria zone where the main East African thunderbelt occurs. Hail storms in Kenya are reported to have been as large as 25mm and do a lot of damage to crops. They usually are expected in the afternoon especially and end of the season.
