Great Migration 2026: Month-by-Month Guide to Africa's Greatest Wildlife Spectacle
The Great Migration is the largest overland wildlife movement on Earth. Each year, approximately 1.5 million wildebeest, 200,000 zebras, and 350,000 gazelles trace an enormous circular route across Tanzania's Serengeti and Kenya's Masai Mara, driven entirely by rainfall and the relentless search for fresh grass.
There is no beginning and no end. The migration is a continuous cycle — and if you know where to look, you can witness some element of it any month of the year.
This guide maps every month so you can plan your trip around the experience you want most.
The Migration Route: The Big Picture
The herds move in a rough clockwise loop across a combined area of about 40,000 square kilometres:
- Southern Serengeti / Ndutu (Tanzania) → January to March
- Central Serengeti (Tanzania) → April to May
- Northern Serengeti / Lamai (Tanzania) → June to July
- Masai Mara (Kenya) → July to October
- Southern Serengeti (Tanzania) → November to December
The Mara River crossings — where herds plunge into crocodile-filled waters in dramatic mass leaps — happen at two key points: when the herds cross north into Kenya (July–August) and when they return south (October–November).
Month-by-Month Migration Calendar
January — Calving Season Begins in Ndutu
Location: Southern Serengeti / Ndutu area, Tanzania
January brings one of the migration's most underrated chapters: calving season. Up to 8,000 wildebeest calves are born every day during January and February, turning the southern Serengeti plains into a nursery.
The calves can stand within minutes of birth and run within hours — they need to. Cheetahs, lions, hyenas, and wild dogs shadow the herds constantly, making predator sightings exceptional. A single morning drive in Ndutu in January can deliver more predator action than a week in a lesser reserve.
What to expect: Hundreds of thousands of wildebeest on the Ndutu plains, daily calving, intense predator activity, large lion prides with cubs.
Best base: Ndutu Lodge or Serengeti National Park camps in the south.
February — Peak Calving, Best Predator Action
Location: Southern Serengeti / Ndutu, Tanzania
February is the peak of calving season. The herds are at their most concentrated in the southern Serengeti, and the predator-prey dynamic is at its most intense. This is one of the best months in the entire year for wildlife photography — the light is good, the grass is relatively short after rain, and animals are everywhere.
February is also a shoulder season for many lodges, meaning more competitive pricing than peak July–September rates.
What to expect: Peak calving, intense predator activity, relatively affordable rates, fewer tourists than peak season.
March — Herds Begin Moving North
Location: Southern and Central Serengeti, Tanzania
As the long rains approach and the southern plains dry out, the herds begin their slow drift northward. Game viewing in the southern Serengeti remains strong through most of March, but by the end of the month the massive concentrations begin to thin.
This is a good time to visit if you want calving-season wildlife without peak-month prices, though weather can be unpredictable toward month's end.
April & May — The Green Season
Location: Central and Western Serengeti, Tanzania
April and May are the heavy rainy season across East Africa. The Serengeti turns brilliantly green. The herds are spread across the central Serengeti corridor, which means game viewing is more diffuse and requires longer drives.
Many camps in the far north close for the season. Accommodation prices drop significantly — 30–50% at many lodges.
Who should visit now: Budget-conscious travelers, birdwatchers (migratory birds arrive), photographers who want the lush green landscape, anyone who wants the Serengeti largely to themselves.
June — The Herds Gather in the North
Location: Central to Northern Serengeti, Tanzania
June marks the shift from green season to dry season. The rains stop, the grass begins to dry, and the wildebeest instinctively sense it's time to move. The herds consolidate and push northward in increasingly large columns — the sight of thousands of animals moving in single file across the plains is spectacular in its own right.
By late June, the lead herds are approaching the Grumeti and Mara Rivers. The first crossings of the season can happen as early as late June.
What to expect: Spectacular herd formations moving north, good game viewing, building anticipation for the crossings.
July — River Crossings Begin, Kenya Arrival
Location: Northern Serengeti (Tanzania) and Masai Mara (Kenya)
July is when the migration enters its most dramatic phase. The lead herds reach the Mara River — the border between Tanzania and Kenya — and face their most perilous challenge: crossing.
The Mara River is home to massive Nile crocodiles that wait patiently for exactly this moment. The wildebeest arrive at the bank, mill about nervously for hours (sometimes days), and then — triggered by some invisible signal — one animal leaps and thousands follow. The resulting chaos of hooves, spray, snapping crocodiles, and thunder is one of nature's most overwhelming spectacles.
By late July, the bulk of the herds are crossing into Kenya's Masai Mara.
What to expect: First major crossings, herds entering the Mara, excellent predator sightings, beginning of peak season crowds.
August — Peak Migration in the Masai Mara
Location: Masai Mara, Kenya
August is the month most people picture when they think "Great Migration." The Mara is full of wildebeest — in the hundreds of thousands — and river crossings happen multiple times per week. This is statistically the most likely month to witness a crossing.
The Mara's famous big cat population is at its most active. Lion prides are well-fed and visible, cheetahs are hunting on the open plains, and leopards appear regularly.
August is also the busiest and most expensive month of the year. Book accommodation 12–18 months ahead.
Tip: A stay in one of the private conservancies bordering the Mara (Olare Motorogi, Mara Naboisho) dramatically reduces vehicle congestion and unlocks night drives and walking safaris.
September — Crossings Continue, Crowds Ease
Location: Masai Mara, Kenya
September is arguably the best overall month. Crossings continue — and if anything, the southern herds are still pushing through — but crowd levels ease slightly from August's peak. Prices at some lodges begin to soften toward month's end.
Game viewing across the Mara remains outstanding. Lion sightings are reliable, cheetah families are active, and the grasslands are golden and photogenic.
What to expect: Continued crossings, slightly fewer tourists than August, superb game viewing, beautiful light.
October — Return Journey Begins
Location: Masai Mara (Kenya) and Northern Serengeti (Tanzania)
By mid-October, the short rains typically arrive in the Mara, triggering the return journey south. The herds cross back over the Mara River. These southward crossings are less predictable but still dramatic — and the banks are lined with far fewer vehicles than in August.
By late October, the bulk of the herds are back in northern Tanzania.
November — Southern Serengeti Beckons
Location: Southern Serengeti, Tanzania
The short rains green up the Serengeti, and the herds race south to reach the new growth. November is an excellent shoulder month — good wildlife, fewer tourists, lower prices. The calving season is still weeks away, so this is primarily about watching vast columns of wildebeest on the move.
December — The Year Ends in the South
Location: Southern Serengeti / Ndutu, Tanzania
December sees the herds settling into the southern Serengeti in anticipation of calving. The plains are green, and the stage is set for January's calving explosion. December is popular for international travelers (Christmas and New Year), which drives up prices — book early if you're visiting over the festive period.
The River Crossings: What You Need to Know
The Mara River crossings are the migration's most dramatic event — and the most unpredictable.
What triggers a crossing? No one fully knows. The wildebeest mill at the bank for hours, sometimes days, before a single animal leaps and the rest follow in a panicked cascade. Weather, the smell of fresh grass, and the behavior of lead animals all seem to play a role.
Can you guarantee seeing a crossing? No. But spending three to four nights in the Mara during July to October gives you a high probability of witnessing at least one.
Where do crossings happen? Multiple points exist along the Mara River. Your guide will know which is active based on where the herds are concentrated that day.
How long should you wait at the bank? Be prepared to wait. Some crossings begin within 20 minutes of arriving; others take half a day. Bring water, a packed lunch, and patience. It is always worth the wait.
Kenya vs Tanzania: Which Side to Visit?
| | Kenya (Masai Mara) | Tanzania (Serengeti / Ndutu) | |---|---|---| | Best for | River crossings, big cats | Calving season, landscape variety | | Peak months | July – October | January – February, June | | Price level | High during peak | Variable — shoulder seasons affordable | | Park fees (2026) | $80/adult/day | $70–$80/adult/day (Tanzania National Parks) | | Getting there | 1 hr flight from Nairobi | Fly-in from Arusha recommended |
The ideal migration trip combines both: calving season in Ndutu (January–February) or river crossings in the Mara (July–October), with the Serengeti as a connecting chapter.
