Weather in Tanzania

Tanzania enjoys a diverse and generally warm climate, thanks to its proximity to the equator and a wide range of altitudes across the country. Coastal regions and islands like Zanzibar tend to be hot and humid, while inland areas, including the Serengeti and Ngorongoro Highlands, offer milder temperatures due to higher elevation. In general, daytime temperatures range from 25°C to 32°C, but nights can be much cooler in elevated areas like Arusha or the crater rim, where temperatures may drop below 15°C.

Tanzania’s year is defined by two rainy seasons and two dry seasons, which significantly influence safari conditions, road access, and the movement of wildlife. The long rains typically occur from March to May, often with heavy showers in the late afternoon or overnight. The short rains come in November and early December, usually lighter and less disruptive.

Between the rainy periods are the dry seasons, which are considered the best times for travel and safaris. From June to October, Tanzania experiences a long, dry stretch with cool mornings and warm, sunny days, perfect for wildlife viewing as animals congregate near rivers and waterholes. The short dry season from late December to February is also popular, especially for witnessing the calving season in the southern Serengeti.

The rainy seasons bring lush greenery, full rivers, and blooming vegetation, creating dramatic landscapes and attracting large numbers of birds, including many migratory species. While off-road travel may be more challenging, these months offer excellent photographic opportunities and fewer crowds in popular parks.

Tanzania’s variety of landscapes—from the snow-capped peak of Mount Kilimanjaro to the white beaches of Zanzibar and the vast savannahs of the Serengeti—means there is always a region in season, no matter when you visit.
