Wildebeest migration in Tanzania — thousands of animals crossing the Serengeti plains in golden morning light

Wildlife Calendar

Tanzania Wildlife by Month

Tanzania Is a Year-Round Wildlife Destination

There is no wrong time to safari Tanzania. The Great Migration is a 12-month cycle — calving in January, river crossings in August, the return south in November. Each month brings a different wildlife spectacle, a different mood in the bush, and different value propositions. This month-by-month guide tells you exactly what to expect, where to be, and how to plan around Tanzania's extraordinary wildlife calendar.

Not to Be Missed

Tanzania's Key Wildlife Events

January-February

Great Migration Calving

800,000 wildebeest calves in 3 weeks. Predator density extraordinary — lion, cheetah, hyena all hunting newborn prey. The most intense wildlife spectacle for sheer volume of vulnerable newborns.

June-July

Grumeti River Crossings

The western corridor crossings are the warm-up act — massive herds crossing the Grumeti River where crocodiles wait. Less visited than the Mara but equally dramatic.

July-October

Mara River Crossings

The greatest wildlife event on earth. Wildebeest and zebra surge across the Mara River in their thousands — crocodiles below, lions waiting above. Allow 3-4 days to witness multiple crossings.

July-October

Tarangire Elephant Season

Tarangire hosts one of the largest elephant concentrations in Africa during the dry season. 1,000+ elephants concentrate around the river. Far quieter than the Serengeti.

November

Short Rains Return

The first rains bring fresh grass and newborn wildebeest foals. The Serengeti turns green, dramatically beautiful, and the most affordable safari month.

Questions Answered

Frequently Asked Questions

What is the best month to see the Great Migration in Tanzania?
July to October offers the most dramatic migration scenes — river crossings at the Mara River in the northern Serengeti are described as the greatest wildlife spectacle on earth. August is peak crossing month. However, every month offers something unique: January-February is calving season (800,000 calves in 3 weeks), which draws predators in huge numbers.
When is the best time to see the Big Five in Tanzania?
The dry season (June to October) is best for game viewing overall — animals concentrate around water sources. Ngorongoro Crater has the highest density of lion, leopard, elephant, buffalo, and black rhino year-round. For rhino specifically, visit Ngorongoro between June and October. Tarangire in July-October hosts extraordinary elephant gatherings.
Is Tanzania good for wildlife viewing in the green season (April-May)?
The green season (April-May) is the most discounted safari period — up to 40% off peak season rates. Wildlife is actually excellent: newborn animals everywhere, predator action intense, birding spectacular with migrants from Europe. Downsides: some roads become impassable, short daily rain showers. But for photographers and budget-conscious travellers, it's magic.
When can I see cheetah cubs in Tanzania?
Cheetah cubs are best seen in the southern Serengeti (Ndutu area) between January and March — peak calving season for Thomson's gazelle coincides with peak cheetah reproduction. The short grass of the Serengeti plains in dry season (June-October) makes cheetah easier to spot anywhere in the park.
What is the best month for birding in Tanzania?
November to April is prime birding season — this is when European migrants arrive (bee-eaters, swallows, wheatears) alongside resident breeding activity. The best single park for birding is Lake Manyara (550+ species) in the wet season when the soda lake fills with flamingos.
