Dry season, calving season or green season? How the weather and the Great Migration change through the year — and what that means for your safari, your climb and Zanzibar.

Tanzania is a year-round destination, but each season offers something different. Here is a simple guide to help you choose your dates.

June to October — the classic dry season

Rain is rare, the grass is short and animals gather around rivers and waterholes, which makes game viewing excellent. From July to September the Great Migration is usually in the northern Serengeti, where the herds cross the Mara River. This is also the busiest time, so book early.

November and December — the short rains

Short afternoon showers turn the landscape green again. The herds move south through the Serengeti, there are fewer visitors and the light is beautiful for photography.

January to March — calving season

In the southern Serengeti and the Ndutu area hundreds of thousands of wildebeest give birth within a few weeks. Predators are never far away, which makes this one of the most exciting times of the year. It is also a good, dry window for Kilimanjaro.

April and May — the green season

The long rains bring lush scenery, quiet parks and lower prices. Some roads become muddy, but wildlife stays — and you often have sightings all to yourself.

Kilimanjaro and Zanzibar

The driest months on Kilimanjaro are January to mid-March and June to October. Zanzibar is lovely most of the year; the long rains around April and May are the only time we suggest avoiding.
