The Great Migration is not a single event. It is a year-round, 1,000-kilometre circular journey made by approximately 1.5 million wildebeest, 300,000 zebras, and tens of thousands of Thomson's gazelles across the Serengeti-Mara ecosystem. Understanding this — that there is no single "best time" but rather different things to see at different times — is the first step to planning your migration safari.
This guide breaks down what you can realistically expect to see in each month of 2026, so you can align your travel dates with your priorities. At Safaris Tanzania, we monitor the migration movements weekly using ground reports from our guides and aerial surveys. This is current, practical intelligence — not marketing copy.

How the Migration Works: The Basic Pattern
The wildebeest follow the rains and the fresh grass that follows. The pattern is broadly predictable:
- December to March: Southern Serengeti and Ndutu area (Ngorongoro Conservation Area) — calving season
- April to June: Western and central Serengeti — the long rains, green season
- July to October: Northern Serengeti and Lamai Wedge — river crossings
- November: Short rains, herds moving south again through central Serengeti
The exact timing shifts by weeks or even months depending on rainfall patterns. Climate change has made the migration less predictable than it was 20 years ago. Our guides track movements in real time — we reposition itineraries when the herds move unexpectedly.
January: Beginning of Calving Season
January marks the start of the calving season in the southern Serengeti and the Ndutu plains of the Ngorongoro Conservation Area. The herds have moved south from the central Serengeti following the short rains in November and December. The first calves appear in early January, building to a flood in February.
January is excellent for wildlife viewing. The landscape is green, the light is beautiful, and the wildlife is dispersed across the open plains. Predator density is high as lions, cheetahs, and hyenas follow the herds. Compared to peak season (July–October), January has significantly fewer visitors and lower accommodation rates.
What you will see: Wildebeest on the southern plains, early-calving, excellent general wildlife (lions, cheetahs, elephants), beautiful green landscape.
Considerations: Afternoon thunderstorms are common. Some camps in the Ndutu area close in January. Road conditions can be muddy after rains.
February: Peak Calving Season
February is peak calving — approximately 8,000 wildebeest calves are born every day. The concentration of vulnerable newborns across the Ndutu plains creates one of the most intense wildlife spectacles on Earth. Predators are everywhere: lion prides working the herd edges, cheetahs exploiting isolated pairs, hyena clans coordinating attacks on separated calves.
This is, in our experience, the most emotionally powerful phase of the migration. Watching a zebra mare bond with her newborn minutes after birth, or a cheetah mother teach her cubs to hunt across the golden grass — these are not rarities in February. They are daily occurrences.
What you will see: Thousands of newborn calves, predator action at close range, vast herds on open plains.
Considerations: This is one of the most popular months for experienced safari travellers. Ndutu area camps book up 6–12 months in advance. Pricing reflects demand. The experience is worth it — but plan ahead.

March: Late Calving, Herds Begin Moving
March sees the tail end of calving — some late births continue, but most calves are a few weeks old and mobile. The herds begin to stir, grazing the short-cropped southern plains as the long dry season approaches. By late March, the first major movements north begin.
March is the transition month — late calving in the south, early green season in the central and western Serengeti. This can be an excellent time for travellers who want calving season experiences without February's premium pricing and crowds.
What you will see: Calving winding down, active herds beginning to move, good predator sightings, transitioning landscapes.
Considerations: The long rains typically begin in late March or early April, which can affect road conditions in the Serengeti. Some operators reduce itineraries in April-May. March visitors should be prepared for occasional rain.
April to May: The Green Season
April and May are the low point of the tourism calendar — and paradoxically one of the most rewarding times to be in the Serengeti. The long rains transform the landscape into a lush green paradise. Fewer vehicles mean more intimate sightings. Prices drop 30–50% at many camps.
The migration herds are dispersed across the western and central Serengeti during these months — not concentrated in one area as they are during calving or crossing season. This means wildlife is more spread out. The experience is quieter, more contemplative, and very different from peak season.
The green season has a particular beauty: dramatic thunderstorms at sunset, baby animals of all species (not just wildebeest), migrant birds arriving from Europe and Asia, and a landscape that looks nothing like the golden savannah of high summer.
What you will see: Green landscapes, baby animals (giraffes, zebras, elephants all calving), fewer vehicles, excellent birding, dramatic skies.
Considerations: Some roads become impassable in April-May due to rains. Some camps close entirely. Game viewing is more dispersed. The trade-off for lower prices and solitude is a less concentrated wildlife experience. Not recommended if your primary goal is seeing the migration herds in large numbers.
June: Herds Gather for the Northern Movement
June marks the beginning of the dry season. The rains stop, the landscape begins to dry, and the migration herds start their massive northward movement from the central Serengeti toward the western corridor and eventually the northern Serengeti. The June window is often overlooked by travellers but is one of our favourite months at Safaris Tanzania.
As the herds move through the western corridor, dramatic crossings of the Grumeti River occur — less famous than the Mara River crossings but spectacular in their own right, with crocodiles waiting and massive hippo pods in the channel. The western corridor is beautiful, less visited, and offers excellent game viewing as the migration herds pass through.
What you will see: Grumeti River crossings, large herds moving north, excellent predator sightings as lions and hyelas follow the migration, green-to-golden transition landscapes.
Considerations: Some of the western corridor camps are more basic than the northern Serengeti camps. This is the tail end of shoulder season pricing — better rates than peak but not the rock-bottom green season prices.
July: Crossing Season Begins
July marks the start of the river crossing season in the northern Serengeti. The herds have reached the Lamai Wedge and the Mara River area. The first crossings begin — sporadic at first, building in frequency through the month.
July is the month when the word "migration" truly comes into its own for many travellers: vast golden plains covered in hundreds of thousands of wildebeest, thundering across the landscape in seemingly uncoordinated but collectively organised movement, heading for the river.
Accommodation in the northern Serengeti is limited and books quickly for July. This is the start of peak season pricing across Tanzania's safari circuit.
What you will see: First river crossings, vast herds in the northern Serengeti, starting to build toward peak crossing activity.
Considerations: Northern Serengeti camps (Lamai Wedge, Kogatende area) are small, remote, and expensive. The game viewing is extraordinary but the logistics and pricing reflect this. July is also school holiday season in Europe and North America — expect more families.

August: Peak Crossing Season
August is the heart of crossing season and one of the most popular months to visit the Serengeti. The herds are concentrated in the northern Serengeti and Lamai Wedge, waiting for the right conditions to cross the Mara River. When the crossing happens — and it is unpredictable in timing — it is one of Africa's most dramatic wildlife events.
Thousands of wildebeest at a time plunge into the Mara River, crocodiles taking advantage of the chaos, the water boiling with movement, wildebeest stampeding back and forth on the bank before eventually committing. A crossing can last hours. Your guide's skill in positioning you at the right crossing point at the right time makes an enormous difference.
August is busy. The northern Serengeti has fewer vehicles than the Masai Mara (Kenya's equivalent crossing area), but sightings can still attract 10–20 vehicles at popular crossing points. This is a trade-off of peak season.
What you will see: Mara River crossings at their most dramatic, vast herds concentrated in a relatively small area, high predator activity.
Considerations: Highest accommodation rates of the year. Advance booking essential — 9–12 months for the best camps. The experience is genuinely extraordinary and worth the premium for many travellers.
September: Maximum Drama
September is the most reliable month for spectacular river crossings. The herds have built to their maximum concentration in the northern Serengeti and Lamai Wedge. The crossings can continue through September and into early October as the wildebeest attempt to cross back and forth between Tanzania and Kenya.
The landscape in September is iconic: golden savannah, vast herds, dramatic crossings, and excellent predator sightings as the concentration of prey attracts lions and hyenas. The weather is dry and cool (by Tanzania standards), the roads are at their best, and the game viewing is consistently excellent.
What you will see: Maximum crossing activity, iconic Serengeti golden landscapes, excellent wildlife density across all species.
Considerations: Same as August — peak pricing, high demand, advance booking required. September is slightly less crowded than August as European summer holidays end. The crossing window is narrower in September than July-August — the herds tend to complete their north-south movement more quickly.

October: Crossing Season Winds Down
October marks the tail end of crossing season. Some late crossings still occur, but the herds are beginning their southern movement back through the central Serengeti. The short rains typically begin in late October, greening the landscape and signalling the start of the next cycle.
October is an underrated month. The crossing season is not over — particularly in the first two weeks — but the crowds have thinned, pricing has softened slightly, and the landscape is transitioning. The short rains bring dramatic cloud formations and excellent photography conditions.
What you will see: Potentially late crossings, excellent general wildlife as the herds move south, dramatic short rains clouds and lightning, fewer vehicles.
Considerations: Predicting exact crossing dates in October is difficult. Some years the herds linger; other years they have already moved south by mid-October. Our guides provide real-time updates and adjust itineraries accordingly.
November: Short Rains, Herds Moving South
November is the short rains season in Tanzania — brief afternoon or evening thunderstorms that freshen the landscape and trigger new grass growth. The migration herds are moving south through the central Serengeti, not concentrated in one area but spread across a wide territory.
For travellers seeking a more affordable safari with excellent general wildlife (not specifically focused on mass migration herds), November is outstanding value. Accommodation rates drop 20–30% from peak. The Serengeti is green and beautiful. Migrant birds from Europe and Asia have arrived. The landscape is at its most dramatic with storm clouds and fresh growth.
What you will see: Green season landscape, migrant birds, baby animals (not wildebeest calving — that's January-March), excellent predator sightings, very few vehicles.
Considerations: The migration herds are dispersed and moving, not concentrated. This is not the time to come specifically to see large wildebeest herds. But for a general safari with some migration presence, excellent value, and dramatic landscapes, November is excellent.
December: Herds Return South
December marks the herds' return to the southern Serengeti plains in preparation for the next calving season. The movement is gradual — by late December the first herds are arriving in the Ndutu area. The short rains have greened the southern plains.
December is popular — Christmas and New Year school holidays in Europe and North America drive significant demand. Accommodation in the southern Serengeti and Ndutu area books up well in advance. Pricing is high for peak-season dates.
What you will see: Herds building in the south, early calving possible in late December, excellent general wildlife, Christmas holiday atmosphere.
Considerations: Peak season pricing. Book 6–12 months ahead for December travel. The calving is just beginning — not at February peak, but the first weeks of the cycle are underway.
Making the Decision: Which Month Is Right for You
Choosing the right month for your migration safari depends on three factors: what you want to see, your budget, and your flexibility on dates.
If you want the most dramatic crossings: July to October, with September being the most reliable. Book 9–12 months ahead and budget for peak season pricing. The experience is worth it.
If you want the most emotionally powerful wildlife experience: January to March, with February for peak calving. This is what wildlife photographers and experienced safari travellers consider the finest months in the Serengeti. Book 6–12 months ahead.
If you want the best value: April to May or November. Significantly lower accommodation rates, fewer vehicles at sightings, green landscapes, and excellent general wildlife. The trade-off is dispersed rather than concentrated herds.
If you have school holiday constraints: December or July-August. Plan 12 months ahead for the best camps. The experience is still extraordinary — just at premium pricing.
How Safaris Tanzania Plans Migration Safaris
We monitor migration movements weekly using our guides' ground reports and aerial intelligence. When the herds move differently than expected — which happens more frequently with climate change affecting rainfall patterns — we adjust client itineraries in real time. This is one of the advantages of booking with a ground operator rather than a pre-packaged tour: flexibility.
A migration safari with Safaris Tanzania is not a fixed itinerary. We plan the route based on where the herds actually are, not where they were historically at this time of year. If the wildebeest are still in Ndutu when you arrive in late March, we take you to Ndutu. If they have moved north earlier than expected in July, we reposition you.
The migration is wild and unpredictable. Our job is to give you the best chance of experiencing it fully, wherever the herds happen to be.
Message us on WhatsApp with your preferred travel month and we will tell you exactly what to expect and build an itinerary around the current migration pattern.
