The Wildebeest Migration is the most spectacular wildlife show on Earth. Over two million wildebeest, zebra, and gazelle move in a giant loop across the Serengeti in Tanzania and the Maasai Mara in Kenya. They follow the rains. They follow the grass. And they never truly stop.

The big question every traveller asks is simple: when should I go? The honest answer is that there is no single best month. It depends on what you want to see: a dramatic river crossing, newborn calves, or big cats on the hunt.

Here is what happens, month by month, so you can plan your trip around the moment you most want to witness.

December to March: Calving on the Southern Plains

During these months, the herds congregate on the grassy plains of the southern Serengeti and the Ndutu area. The grass is rich after the short rains. This is the perfect nursery.

Calving season peaks in late January and February. Around half a million calves are born in just a few weeks. It is a stunning sight.

It is also a feast for predators. Lions, cheetahs, and hyenas are never far away. If you want big-cat action and baby animals, this is your window.

Best for: calving, predator sightings, and fewer crowds.

April to May: The Long Rains and the Move North

Now the long rains arrive. The plains begin to dry. The herds sense the change and start moving northwest into the central Serengeti.

This is the green season. Landscapes are lush and beautiful. Prices are often lower, and parks are quieter.

The trade-off is rain. Showers can be heavy, and some roads get muddy. But the scenery is gorgeous, and the herds are on the move.

Best for: scenic value, photos, and relaxing game drives (in their personal vehicles).

May through June: Rut and Grumeti River

Late in May, the Great Migration has moved into the Western Corridor of the Serengeti. This is the rutting (mating) season for the animals, and you can hear all the males grunting at each other.

The herds also face their first big test: the Grumeti River. Crocodiles wait in the water. The crossings here are smaller than the famous ones later, but still thrilling.

Best for: the rut, early river crossings, and dramatic build-up.

July to August: From July through August, the Iconic Mara River Crossings are at their Peak

This is what most people picture when they think of migratory animals: a herd entering the northern Serengeti and arriving at the Mara River. They will only be able to proceed north by crossing the river. The mara is a wide, swift river filled with crocodiles. Thousands of animals gather on the river banks and, after a short pause, jump into the river. The experience is chaotic, tense, and memorable.

By late July and August, many herds cross into the Maasai Mara in Kenya. The crossings can happen daily, though never on a fixed schedule.

Best for: the iconic river crossings, the highlight of the whole migration.

September to October: Peak Drama in the Maasai Mara

Now the action centres on the Maasai Mara. The herds graze the golden grasslands, then cross back and forth over the river in search of fresh grass.

September is one of the best months to be in the Mara. The weather is dry and clear. Crossings are still common, and predator activity is high.

This is peak season, so book early. Lodges and camps fill up fast.

Best for: classic Mara safaris, big crossings, and reliable wildlife viewing.

November: The South Turn

As the short rains return, the herds feel the pull south again. They begin the long journey back toward the Serengeti plains.

November is a quieter month. The landscape turns green once more. You can still find large herds on the move, and the crowds have thinned.

Best for: beating the crowds and catching the migration in transit.

A Quick Planning Summary

• Get your group together for the river crossings from July to October in the northern Serengeti and Maasai Mara.
• Hunt for calving and predator activity from late January to late February in the Southern Serengeti.
• The green season is ideal between April and May throughout the Central Serengeti.
• The rut will occur between May and June in the Western Corridor.

The migration is a year-round event. The herds are always somewhere. The trick is matching your travel dates to the chapter of the story you most want to see.

Know the Better Time to Arrive During Migration 

The migration does not happen the same way every year due to rain; the timing of the migration can be different from what’s reported. Herd movements will occur at least 1-2 days (and sometimes up to two weeks) before they do every year; thus, local knowledge is critical.

At La Pisada Africa Safaris, we track the herds across both Kenya and Tanzania. We know which camps to choose, when to book, and how to position you for the best sightings.

Plan your trip with us, and we’ll build your safari around the herds.
