Serengeti Wildebeest Migration Month-By-Month Guide 2025/2026
Nature stages the greatest natural show in the northern part of Tanzania and the southwestern part of Kenya. The Great Migration. This event happens in the mighty Serengeti ecosystem, which consists of many conservancies, including Tanzania’s Serengeti National Park and Kenya’s Masai Mara National Reserve.
Every year, about 2 million wildebeest, zebra, and gazelle migrate from the south to the north in their search for greener grazing grounds. Many visitors love the famous river crossing part – a grand final scene of the event – but there’s much to see in this event. And that’s why we’re here to give you a month-by-month guide to this wonderful event.
What causes the wildebeest migration?
The main drive of this natural phenomenon is the search for green pasture. The wildebeest has an instinct to sniff out rain miles away. Once they know it, they move in massive herds following the rain. How do they tell each other to move in the same direction, and which route to follow? That’s still unknown. But here’s a fact:
The wildebeest are good at detecting rainfall several kilometers away. But zebras are better at following and remembering migration routes. This is why these plains animals move together every season.
So, here is your month-by-month guide
November
Rainfall starts in the south of the Serengeti, making the region and Ndutu greener. The migrating animals, in small herds, are the eastern (Namiri) plains moving faster to arrive on the calving grounds.
December
This month, the vast plains of the Southern Serengeti turn green. These plains stretch into the Ndutu area of the Ngorongoro Conservation Area. The animals spread across the whole region to find green grass in the region.
January
The plains turn into a ‘maternity ward’ for over 500,000 calves. And sometimes, the animals can give birth to up to 8,000 new lives. This is the best time to view young animals spread everywhere in the region.
Predators like lions, leopards, cheetahs, and hyenas never fall behind their prey. They survey the fringes to devour on vulnerable newborns. Therefore, it’s also the best time to see predators in action.
February
The calving season is at its prime stage. Hundreds of thousands of calves join the wildebeest, making the herds even bigger. This is the best time for witnessing beautiful newborns taking their first steps.
The weather is dry and warm. In addition, many mobile camps move to this area. So, there are plenty of places to stay in this region of the Serengeti.
March
Early March is dry like February, but as time goes on, downpours begin. The herd spread across the vast plains of Serengeti South and Ndutu. Calving continues in the early start of the month, but not much.
Late March is wet and lush. The trails might be muddy and slippery, hence, driving becomes so challenging. However, you can enjoy seeing birds, predators, and other animals. Some camps close as April approaches. Book early to save your spot.
April
As April sets in, animals in big herds start moving. This time, they follow a north route via Moru Kopje heading to the Seronera Valley. There’s much to see this month, including massive herds sweeping the plains and the rutting season.
However, the rainfall is always heavy and frequent during this time, making the vegetation thick and the trails muddy. But birdwatching is excellent.
May
By this month, the wildebeest migration is in the central Serengeti. Known for the big cats, the plains of Seronera welcome big herds of wildebeest. Predators try their luck to get delicious meals from the herd.
The herd then spread in the Moru Kopjes on its way to the Western Corridor. There’s so much to see, including resident animals of the central Serengeti and more.
June
The migration now faces the first serious obstacle: the Grumeti River. Though they’re not famous, Grumeti River crossings are worth watching. There’s no crowd here, so you enjoy the dramatic scenes on your own.
July
After crossing the Grumeti, a portion of the herd enters the private Grumeti Reserve and continues its course into the Ikorongo Game Reserve. They then leave the game reserves and join the other herd on the banks of the Mara River. The other herd moves northwards directly via Lobo.
August
This month, we witness one of the fascinating events of the wildebeest migration. Animals slowly start crossing the crocodile-infested waters of the Mara. The hungry, ruthless Nile crocs stay submerged under the water, waiting for the right time to attack.
However, let’s be honest. Animals cross the river at their will, and sometimes they may not do that for even two days. So, it’s hard to say you’ll witness a crossing anytime you want. But there’s a greater chance is staying longer (3-4 days).
September
River crossings continue. Animals spread into the Lamai Wedge and the Masai Mara. Depending on the season, September can be a great month to see the Great Migration from Kenya’s Masai Mara. They spread across the Mara Triangle.
October
The migration is still in Kenya’s Masai Mara. But as late October sets in, they slowly start heading southeast of the Masai. They cross the Mara River, and this time, they enter the Loliondo Game Controlled Area.
There might be some river crossings to witness during this time, but it depends on the migration pattern. And if a river crossing happens, it’s always direct and faster as animals head south to calve.
How do calves survive in the Serengeti?
Many guests ask our guides this question. Of course, nature is so brutal to the vulnerable baby wildebeest. Getting into the stage where every predator is salivating is so tricky. But they have survival instincts. Here’s how they survive:
- They can stand still after minutes of birth. The calves are born ready to fight for their lives. In just minutes after birth, they stand on their feet and start running after just an hour. This unique adaptation makes them increase their survival chances in the predator-infested plains of Ndutu.
- The wildebeest mothers form natural barriers to protect their newborns. It’s very inspiring to see how these animals collaborate to protect the calves. They would ring a cycle around young ones and make sure that only adult wildebeest form the fringes.
The bottom line
The Great Migration is an uncertain natural phenomenon. The animals have their clocks. But we do our best to ensure you get the most out of this crucial event. And there’s much to experience.
So, if your timeline doesn’t coincide with the Mara River crossings, you can opt for lesser-known experiences like Grumeti River crossings and the calving season. With expert field guides, you stand a chance to watch even unpredictable moves of the migration.
