Dry Season May to September – Winter

There is virtually no rainfall during the whole of winter and the humidity is very low. Water becomes scarce in the bush, and animals are drawn to permanent water sources.

  • May – This is a transitional month and marks the end of summer. Temperatures are cooling down to typically 11°C/52°F in the morning and 28°C/82°F in the afternoon.
  • June, July & August – Morning game drives in open vehicles will be cold, so it's advisable to pack warm clothing. The average morning temperature is 11°C/52°F. Afternoons will be pleasant with temperatures around 25°C/77°F and cloudless skies.
  • September – The heat gradually builds to about 27°C/81°F in the afternoon, and the first rains bring relief from very dry conditions. Mornings are mild, with temperatures around 15°C/59°F.
