Botswana / Climate
Most southern African countries are largely influenced by the same weather patterns with the dry season falling over the austral winter months of May to October and the summer months featuring rainfall in varying degrees over the months November to April. Botswana is no exception.
Lying on the edge of the Kalahari Desert, the Okavango Delta experiences an annual average rainfall of only 18.5 inches (470mm). The bulk of this falls in the period December to March with lesser amounts recorded in the months immediately either side of this. Rain typically falls in short thunder showers in the late afternoon which produce spectacular dark skies and vivid rainbows before passing.
The daytime temperatures during this summer period are typically high with 32°C (80°F) an average daily high. Night time temperatures in the summer seldom drop below 17°C (65°F). During the dry winter months of May to September negligible rain falls and vegetation dries out significantly. During this period temperatures can drop quite low and warm clothes are recommended for the evenings and early morning activities. The average daytime high temperatures is around 27°C (70°F) while overnight the mercury typically averages around 8°C (30°F) and can drop much lower.
