In general, the whole of Botswana follows a fairly similar weather pattern with November, December, January and February situated slap bang in the heat and rain of mid-summer. The Kalahari in particular is stifling. However, there’s plenty of greenery as well as the chance to see newborn animals alongside an abundance of migratory birds.
March is also a wet month although rainstorms tend to be confined to afternoon showers, especially as you enter into the month of April.
May signals the start of the dry season, with clear skies and moderate temperatures.
June, July and August are some of the best months to visit the Okavango Delta, Moremi Game Reserve and Chobe National Park as the wildlife is out in abundance. But be prepared for surprisingly chilly temperatures, especially for early morning game drives.
September and October are dry, hot and dusty with not much in the way of bird watching but also not many mosquitoes and less vegetation. This means this is often considered the best time to visit Botswana as wildlife clusters around the diminished waterholes, and there is little greenery to block the fantastic scenes.
