The best months to visit Namibia are between the months of May and October, when the weather is dry.
These are Namibia’s winter months and the conditions make it perfect to go on an adventure, especially in the Etosha region and with the cool weather, spending hours on the road are a lot more comfortable.
During this time of the year, the skies are mostly clear, and there is also a very low risk of contracting malaria. The dry months are also optimal for wildlife viewing, because the animals tend to congregate around watering holes. The lack of rain also means that it is easier to view wildlife since the vegetation is not so overgrown that it blocks out the view.
While the weather is sublime at this time of year, it is still winter. Mornings and evenings can get frigidly cold, with occasional frost in some places in June and July. By September and October, the winter is long gone and the days become hot. Summer rains fall between November and April, and can be so heavy that sometimes parts of the country flood.
