When is the best time to visit Tanzania?

The best time to visit Tanzania depends on what wildlife you’d like to spot. The country’s seasons and wildlife numbers are dictated by the rains, so you’ll have a slightly different experience depending on when you choose to visit. 

Tanzania’s headline attraction is the Great Migration, which occurs year-round across the Serengeti. Many people flock here between July and September for a chance to witness huge herds of wildebeest and zebra crossing the Mara River — panic ensues as they try to avoid the jaws of crocodiles and other predators waiting to pounce. You’ll see lots of vehicles in the park at this time of year, though. 

Tanzania’s ‘green season’, between November and March, is much quieter. While there’s a chance of rain showers, it’s a fantastic time for birdwatching as migratory species arrive in their thousands. You’ll also see Great Migration herds with their newly born calves. 

The only time we tend to avoid Tanzania is between April and May, when heavy rains can disrupt wildlife viewing.

The best time to visit Tanzania is from July to October when the country is at its driest. This coincides with the migration river crossings, however, all the parks offer amazing wildlife sightings at this time as the grasses and bush are at their least dense.

Month-by-month guide to traveling in Tanzania

Visiting Tanzania in January

There is a chance of rain, the temperature is getting higher and the humidity is building. It's still a good time to go as rates are lower and safari is excellent. At this time of year the migration herds are in the southeast of the Serengeti for calving season, so the Ndutu Plains are busy but it is amazing to see so many animals in one place.
