Traveller notes on Gaborone in September

Other months in Gaborone

Forum posters describe November days across Botswana as running quite hot, typically in the 30sC, with rain usually holding off until later in the month even though scattered earlier showers remain possible. Posters describing a November-into-December visit reported little rain overall, cool mornings and warm afternoons, with heat never once disrupting a game drive. Posters consistently rate November and December as offering lower rates alongside still-excellent wildlife viewing, since even a modest chance of rain hasn't scared off the animals - if the rains do start early, the bush greens up and temperatures ease slightly, timed with wildebeest and impala births. Posters generally rate November as hot but very manageable for a Botswana visit, with real value in the shoulder-season rates.

Forum posters describe May as a genuinely excellent shoulder-season month across Botswana generally - clear skies, comfortable daytime warmth, and almost no rain, sitting right at the start of the dry season. Posters are consistent that nights and early mornings turn noticeably cold despite the pleasant days, recommending a fleece, hat and gloves for anyone out early, with overnight lows commonly cited in the teens Celsius or cooler. Posters generally rate May as offering some of the best value of the year - fewer crowds and lower prices than the peak winter season just ahead, with the dry, clear conditions making it a comfortable month for exploring the wider region around Gaborone.
