Best Time for the Serengeti Migration: A Month-by-Month Guide.

The Migration Isn't a Schedule — It's a Response to Rain

Roughly two million wildebeest, zebra, and gazelle move in a clockwise loop of about 800 kilometers across the Serengeti-Mara ecosystem, following the rain rather than a calendar. That's why exact crossing dates shift by weeks from year to year — the pattern below is a reliable guide, not a guarantee.

January – March: Calving Season in the South

The herds concentrate on the short-grass plains of the Southern Serengeti and the Ndutu area, part of the Ngorongoro Conservation Area. This is calving season — over 500,000 calves are born in a six-to-eight-week window, with as many as 8,000 births a day at the peak. The open plains make for exceptional predator sightings, since lions, cheetahs, and hyenas concentrate around the vulnerable newborns.

April – May: The Long Rains and Northward Push

As the rains set in, the herds begin stretching north through the central Serengeti toward the Western Corridor. Grass is lush, roads can be muddy, and the herds are more spread out than during peak season — but this is also when camp rates hit their lowest point of the year.

June – July: The Grumeti River Crossings

The leading columns reach the Western Corridor and face their first major obstacle: the Grumeti River. These crossings carry real drama — including crocodiles — but draw far fewer vehicles than the famous Mara crossings later in the season, making them a quieter alternative for travelers who still want crossing footage.

August – October: Mara River Crossings and Peak Season

This is the window most travelers picture when they imagine the migration: herds pouring across the Mara River into Kenya's Maasai Mara and the northern Serengeti simultaneously. August is generally considered the statistical peak for crossing frequency, with river-side vehicle congestion at its highest. Camps in this zone fill 12–18 months in advance for good reason.

November – December: The Return South

As the short rains begin, the herds turn back south, passing through the eastern Serengeti toward Ndutu ahead of the next calving season. This transitional period offers green scenery, thinner crowds, and a good chance of catching resident wildlife around Seronera along the way.

Choosing Your Migration Window

For river crossings, target July through September and book camps in the northern Serengeti or Mara well in advance. For calving season and big cat action, aim for late January through February in the Ndutu area. If you want migration scenery without the crowds or the premium pricing, April, May, and November are worth serious consideration.

How We Track the Herds

Migration timing shifts with the rains, so we monitor real-time herd movement reports from guides on the ground before finalizing your camp locations — not just historical averages.
