Botswana weather is generally quite enjoyable. The hottest time of year in Botswana is also the wettest. The rainy season occurs in summer between October and April. Dry and cool weather, with cold and often frosty nights, occurs between May and September, when the average daytime temperature is a pleasant 77ºF (25ºC). The months between April and October are ideal for tourists in terms of weather and game viewing. This is the time when the wildlife is most prolific and easily spotted around the natural watering holes and dams.
