Masai Mara Migration Calendar: Where to See the Wildebeest Each Month

The Masai Mara migration calendar follows the northern phase of the Great Wildebeest Migration, when large herds of wildebeest, zebra, and other grazers move from the Serengeti National Park into Kenya’s Masai Mara. The Masai Mara National Reserve is usually most closely associated with the migration between July and October, when the herds arrive in search of fresh grazing and water. However, the great migration in Africa is a continuous annual cycle across Tanzania and Kenya, not an event with fixed start and end dates.

The most famous part of the Masai Mara migration is the Mara River crossing season, as observed by our Serengeti Masai Mara Experts. So, herds gather along the Mara River for hours or even days before crossing, and there can be long periods without a crossing. Rainfall, grass availability, water levels, herd pressure, and the location of the animals all influence when and where a crossing takes place.

Masai Mara Migration Calendar at a Glance

For most migration-focused safaris, July to October is the key period to consider based on the Masai Mara Migration Calendar. July can bring the first major arrivals; August and September commonly offer strong opportunities for large herds and river crossings, while October can still produce migration activity as the herds begin responding to changing conditions and moving back towards the Serengeti.

This Masai Mara migration calendar explains the migration month by month, including where the herds are likely to be and what you can expect to see. Lastly, when the Mara River crossings usually occur and how to choose your safari dates for the wildebeest migration in Masai Mara without relying on fixed or guaranteed migration dates.
