Sara and John say...
Botswana’s climate is typical of southern Africa.
The summer months between December and March are wettest and warmest, but the rains are less intense than countries further east. It’s not a period of relentless rain. Some days will be hot and sunny, especially in the desert. Some will see heavy afternoon thunderstorms and some will just be grey.
Humidities are high through this period too. In fact this is most noticeable at night when temperatures typically remain in the 20s Celsius.
April and May see the dry season emerging amidst a fresh green landscape. It does turn less warm too, especially at night. Indeed the Kalahari night begins to turn quite chilly.
June to August is the peak season for safari. Under clear skies, animals congregate around the water sources. Days can get very warm, while nights are cold, with the contrast most striking in the drier desert areas.
Big game safari reaches a peak in September and October. The days are becoming more humid and uncomfortable, with daytime highs reaching the low 40s Celsius in low-lying areas.
Most days are still dry, although showers become more likely. However, it’s not until November when downpours more reliably arrive, ahead of the wetter months that follow.
