Botswana has a semi-arid climate and the weather is reasonably hot and dry for most of the year, and rainfall is scarce. Showers are unpredictable and localised, but most of the rain that does fall comes during the summer months between November and March.
The wettest part of the country is in the north, with the precipitation peaking in January and February. The amount of rainfall decreases the further south one travels.
Winter in Botswana, from May to August, is almost completely dry, with warm, sunny days and very cold nights, with temperatures dipping below freezing in some areas. Humidity levels are also very low in the winter months, adding to the pleasant conditions, and resulting in crisp, clear weather.
The transitional seasons between summer and winter are pleasant and dry, without the extreme cold nights of winter.
