Climate Chart Okavango Delta – 934-1,024m / 3,064-3,360ft

The Okavango Delta has a climate that is warm to hot, and it experiences distinct Dry (April to October) and Wet (November to March) seasons. The rains break the buildup of heat in November or December (the exact timing is unpredictable) and come as a relief. The last rain of the Wet season usually falls in April. It’s worth remembering that water levels are higher during the months of low rainfall as it takes time for rainwaters elsewhere to flow into the Delta.

Dry Season –April to October

June and July are the coolest months, but temperatures begin to increase in August and peak in October. Bring warm clothing for early morning game drives and boat trips.

April & May – This is the beginning of the Dry season, but the vegetation in the Delta is still green. There is plenty of sunshine and conditions are mostly dry. Afternoon temperatures average 31°C/88°F, making the days feel pleasantly warm.
June, July & August – It is usually very dry and somewhat cooler now. Afternoon temperatures climb to a pleasant 26°C/79°F on average. However, early mornings can be cold at about 11°C/52°F.
September & October – It gets hotter and hotter at the end of the Dry season before the rains bring relief from the oppressive heat. October is stifling, with average temperatures of 34°C/93°F. Nights and early mornings are more pleasant.

Wet Season –November to March

The arrival of the rains cools things down, and the dust settles. Afternoon thunderstorms and short showers become normal. It remains warm throughout the Wet season, with afternoon temperatures averaging 34°C/93°F. Mornings are a lovely time to be active.

November & December – It only rains every now and then. Mostly it’s hot and sunny. The rain comes as a relief because temperatures build beforehand and drop after. Early mornings are the most comfortable time, with temperatures around 20°C/68°F.
January & February – These months receive the most rainfall. It rains many afternoons, but it rarely lasts longer than a few hours. Powerful thunderstorms are common.
March – The rains are diminishing in March. It still rains every couple of days though, usually in the form of a storm. Mornings are a little bit cooler at around 17°C/63°F.
