Located in an arid to semi-arid desert climate, Karoo is prone to wide variations in temperature and little to no rainfall. The park receives an average rainfall of 190mm/7.5in per year and is subject to periods of drought.

Although the annual average minimum and maximum temperatures are 9°C/48°F and 24°C/75°F respectively, the climate is one of extremes, and temperatures range from –15°C/-27°F on the plateau in winter to over 40°C/104°F on the plains in summer.

Winter –May to September

Winter is a time of relative drought. The nights tend to be very cold, and frost is common. It is essential to bring warm clothes. Days aren’t very warm, but pleasant in the sun.
