Game viewing in Tanzania is at its best between June to October. To witness the Great Migration in the Serengeti, visit from May to July when the plains are fresh and green or November to March when the herds return to calve. The hottest months are from December to March. The rainy season occurs in April and May, there are often short rains in November and December and the driest season is June to October. The coast is hot and humid through the year. The Serengeti and especially Ngorongoro Crater can be cold at night throughout the year because they are on a high plateau.

Tanzania is sunny and tropical (accept in the mountain regions). Given the sheer size of the country, the climate varies dramatically in different regions. In coastal regions and on the islands of Zanzibar and Pemba it is hot and humid year-round with higher rainfall, whilst inland, the central plateau is dry and hot and the north-western highlands are cooler. The long rains occur between mid-March and the end of May and there are also short, lighter rains during November and December. The driest months are June to October.
The endless plains of east Africa are the setting for the world’s greatest wildlife spectacle – the pounding of more than 6 million hooves during the Great Migration. From the Serengeti plains in Tanzania to Kenya’s Masai Mara over 1 million wildebeest, 300,000 Thomson’s gazelle and some 200,000 zebra, relentlessly tracked by Africa’s great predators, migrate in a clockwise fashion over 1,800 miles each year in search of rain ripened grass.
The precise timing of this incredible event is hard to predict, as the path of the wildebeest migration is dependant on rain. The animals follow the path of the rain in order to feed off the new grass whilst also being close to a good water supply. If you'd like to time your trip to Tanzania or Kenya to watch this incredible event then here's our guide to the migration.
From December to February the wildebeest congregate in the Serengeti region. In the Serengeti an estimated 400,000 wildebeest calves are born during a six week period early each year - usually between late January and mid-March. From March to May/June, the wildebeest migration moves north following the rain, to the Lake Victoria region. From July to August the wildebeest migration heads east to the Masai Mara in Kenya, returning south across the Tanzanian border around November.
