Wildebeest herd during the Great Migration in the Serengeti

The Great Migration is one of the most spectacular wildlife events on earth: over a million wildebeest, plus hundreds of thousands of zebra and gazelle, moving in a constant loop across the Serengeti in Tanzania and the Masai Mara in Kenya. But the migration never stops moving, so timing your trip is everything. Here is what to expect month by month.

December to March: calving season in the south

The herds gather on the short-grass plains of the southern Serengeti and Ndutu area. Around late January to February, roughly half a million wildebeest calves are born within a few weeks. This is a superb time for predator action, as lions, cheetahs and hyenas follow the vulnerable young.

April to May: the long rains

This is the low season. Rain is frequent and some camps close, but the landscape is lush and green, prices drop, and there are far fewer tourists. If you do not mind occasional showers, this can be a wonderful value period.

June to July: the rut and the western corridor

The herds move north and west. June is the start of the mating season, and by July the migration reaches the Grumeti River. This is the beginning of peak season, with excellent weather and dramatic river crossings starting to build.

August to October: the famous river crossings

This is the most sought-after period. The herds face the crocodile-filled Mara River in the northern Serengeti, and the dramatic crossings are the images most people picture when they imagine the migration. Book well in advance, as camps sell out months ahead.

November: the short rains and the journey south

Short rains arrive and the herds begin moving back south towards the calving grounds, completing the annual loop. It is a quieter, greener time with good value.

So when should you go?

For river crossings, aim for August to October. For baby animals and big cat action, choose January to February. For the best value and fewer crowds, consider the green seasons. Whatever you choose, a knowledgeable local guide who tracks the herds daily is the key to being in the right place.
