The best time to go to Tanzania and Zanzibar is anytime outside the rainy season from March to early May. June to September is the dry season and the best time to see the Great Migration in the Serengeti with little chance of rain in Zanzibar. January and February also offer good options, outside peak season rates. See our climate guide and advice from Tanzania and Zanzibar experts below. The best time to visit Tanzania is from late June through October when the country is at its driest. Of course, different people want different things from their time in this breathtaking East African country, which can make other seasons optimal as well. Some are hoping for optimum game viewing in the world-renowned reserves of the Northern Circuit, while others want good weather for a relaxing break at the beach. Weather is also a critical factor in being able to summit Mount Kilimanjaro or Mount Meru; while many visitors want to be in the right place at the right time to witness the annual Great Migration.

Most safari areas in Tanzania enjoy warm days and cool evenings year-round. While temperatures drop to below freezing on Mount Kilimanjaro and Mount Meru, the country’s Indian Ocean coast and lakeside regions are hot and humid. Tanzania has two distinct rainy seasons: April to May (the ‘long rains’) and November to December (the ‘short rains). Generally, the country’s main rainy season (the long rains) produces tropical downpours in the afternoons and many safari camps close. The short rains season sees the occasional brief shower, but safari camps stay open and game viewing is good.
