The dry season, which lasts from late June to October, is the best time to visit Tanzania for a safari. The majority of safari locations in Tanzania have warm days and cold evenings throughout the year. While temperatures on Mount Kilimanjaro and Mount Meru plunge below zero, the country’s Indian Ocean coast and lakeside regions are hot and humid.
The best time to visit Tanzania depends on where you want to go and what you want to see. The best time to visit Tanzania for first-time safari travellers is usually during the dry season when wildlife is simpler to follow and spot.
The Best Time to Visit Tanzania for a Safari to See Wildlife

From June to September, the weather is colder and dryer, with most days being sunny. Because the foliage is scant and the animals concentrate around limited water sources, finding them is easier. The Serengeti wildebeest migration typically occurs in June and July. During this period, hotels in popular places are frequently full, with high-season rates in effect.
The Best Time to See the Great Migration

The Great Migration in Serengeti National Park is one of Tanzania’s most popular attractions. Every year, travellers from all over the world flock to see the massive passage of animals across the Grumeti River. It is one of the reasons the Serengeti is a UNESCO World Heritage Site, as it is the world’s largest wildlife migration.
Herds of wildebeests and other ungulates visit Kenya for a brief time each year (about two months). Typically, they move there in July and August, risking crocodiles and other predators to return to the lush grass of the Maasai Mara. The herds spend the rest of the year in Tanzania, primarily in the Serengeti or a section of the Ngorongoro Conservation Area. For around 10 months of the year, they will mate, give birth to their young, and enjoy the rich grasses of the Serengeti.
The Best Time to Visit Zanzibar

The best time of year to visit Zanzibar is between July and September when it is warm and balmy, and then again between December and February when it is usually dry. Zanzibar has a wet season during the months of March, April, and May.
Travellers to Zanzibar go for a variety of reasons. The exotic island off the coast of Tanzania offers a wealth of things to do for every discerning traveller. From strolling along the white sandy beaches and snorkelling in the warm Indian Ocean to inhaling the fragrances of different spices on an excursion in Stone Town.
Combining Zanzibar and the Great Migration
Those visiting Tanzania can combine a safari with a beach holiday to Zanzibar. The country is diverse and makes travelling very easy. The extraordinary Great Migration is a must-do on every African bucket list, so why not start or end your African holiday with some fun on an island?
