In Mlilwane, winter and summer correspond to the Dry and Wet seasons respectively. Here, winter and summer are at the opposite times as Europe and North America. The wet summer months (October to April) are warm and often humid. Dry winters (May to September) are mild.

Dry season May to September – Winter

There is little rainfall during the winter months and the humidity is low. Animals are attracted to permanent water sources as water becomes scarce in the bush.

  • May – Marking the end of summer, May is a transitional month. Temperatures are typically dropping to a shivery 8°C/46°F in the morning and 21°C/70°F in the afternoon.
  • June, July & August – Morning game drives in open vehicles will be very cold, so it's advisable to pack warm clothing. The average morning temperature is a paltry 6°C/43°F. Afternoons will warm up nicely with temperatures around 19°C/66°F, and cloudless skies.
  • September – It eventually warms up to about 22°C/82°F in the afternoon, and the first rains bring relief from very dry conditions. Don’t forget your jacket in the early mornings when the mercury only struggles up to 9°C/48°F.

Wet season October to April – Summer

It rarely gets hot in summer, although it is fairly warm. Average temperatures during the day reach 25°C/77°F with high humidity. Storms crash through in the afternoon.

  • October & November – Expect more heat and more rain during these months. Temperatures range between 12°C/54°F in the morning and 24°C/75°F in the afternoon.
  • December, January & February – Known as the wettest and warmest months, characterized by torrential downpours in the afternoon (the humidity can be stifling). Afternoon temperatures are usually around 25°C/77°F but peak temperatures shoot much higher.
  • March & April – Rainfall drops off and it gets colder. April is generally fine. The nights get a bit chilly at about 11°C/52°F, but daytime temperatures peak at around 23°C/73°F, with the humidity dropping off.
