Botswana

The winter, from May to August, is dry and sunny, mild during the day but cold at night, especially in the center and south. The summer, from November to March, is hot and moderately rainy because of thunderstorms that break out in the afternoon or evening; therefore, there's plenty of sunshine even in this season, especially in the morning. In spring, in September and October, the heat is often intense especially in the north, however, hot days are possible throughout the country from September to April.

The wettest areas, where more than 500 mm of rain fall per year, are the north and the south-east, where Gaborone is located. In general, rainfall in the warm season is not very abundant, but during some years, it can be more abundant than usual, when the country is reached by moist air masses from Congo, or because of the remains of cyclones.
