Serengeti Great Migration: Month-by-Month 2026

Every year, 1.5 million wildebeest, 200,000 zebra, and 350,000 Thomson's gazelle make a continuous 800-kilometre loop through the Serengeti and Masai Mara ecosystems. This is the Great Wildebeest Migration — often called the greatest wildlife spectacle on Earth. The herds never stop moving. The question is not whether the migration is happening. It is always happening. The question is which phase you want to witness.

This guide gives you the complete month-by-month breakdown for 2026, including where the herds are, what you will see, how crowded it will be, and what a 5–10 day migration safari costs through Safaris Tanzania. No agent markups. No vague estimates. Real pricing from a direct operator who has been watching these herds since 1978.

How the Migration Works

The herds follow the rains and the fresh grass that follows. The loop runs roughly clockwise:

• June–October: Dry season. Herds concentrate in the northern Serengeti and Masai Mara (Kenya), crossing the Mara River back and forth as they pursue emerging grass.
• November–December: Short rains arrive. The herds begin drifting south through the central Serengeti toward the short-grass plains of the south.
• January–March: Calving season on the southern Serengeti and Ndutu plains. Approximately 8,000 wildebeest calves are born every day for 3–4 weeks.
• April–May: Long rains. The herds move north-west through the western corridor, crossing the Grumeti River before consolidating for the northern push.

The exact timing shifts 2–4 weeks each year depending on rainfall patterns. The calendar below reflects typical timing for 2026.

Month-by-Month: Where the Herds Are and What to Expect

January — Southern Serengeti (Calving Season Begins)

Location: Southern Serengeti, Ndutu area, short-grass plains

What you see: Calving season starts in earnest. Pregnant wildebeest arrive on the short-grass plains in their thousands. Newborn calves — 8,000 per day at peak — are on their feet and running within minutes. Every predator in the ecosystem converges on the plains: lions, cheetahs, hyenas, and wild dogs. This is sustained, intense wildlife action from dawn to dusk.

Crowd level: Moderate. Significantly fewer vehicles than July–August.

Price: Mid-season. Strong value given the quality of wildlife viewing.

February — Peak Calving (Southern Serengeti / Ndutu)

Location: Southern Serengeti, Ndutu plains, Ndutu woodland

What you see: The most intense predator-prey spectacle in Africa. The calving peak means prey is everywhere — and so are the hunters. Lions make kills in full daylight on open plains. Cheetahs sprint across the short grass with unobstructed sightlines. Hyena clans of 20–30 work the edges of the herds. This is Safaris Tanzania's top-recommended migration experience for first-time safari travellers.

Crowd level: Low–moderate. The best-kept secret in the Serengeti calendar.

Price: Mid-season. Lower than July–August by 20–30%.

March — Green Season (Central / Western Serengeti)

Location: Central Serengeti (Seronera) and western corridor as the herds begin moving

What you see: Long rains are arriving. The migration is less concentrated — herds are spreading and moving rather than bunching. The central Serengeti (Seronera area) has excellent resident wildlife year-round regardless of migration position. Leopard sightings at the Seronera riverbanks are consistently strong in March.

Crowd level: Low. March is one of the quietest months in the park.

Price: Low season. Best value in the calendar.

April — Long Rains Peak (Western Corridor)

Location: Western Serengeti corridor, Grumeti area

What you see: April is the wettest month. Some roads become difficult. The herds are in the western corridor moving through the Grumeti concession. Grumeti River crossings begin — smaller than the Mara but with enormous Nile crocodiles that make crossings dramatic. The landscape is vivid green and empty of tourists. Some camps close for the low season.

Crowd level: Very low. The parks are near-empty.

Price: Lowest of the year. 20–30% below shoulder season.

Honest assessment: Not recommended for first-timers. Best for experienced Africa travellers who understand the trade-offs and want near-solitude in the ecosystem.

May — Rains Ease (Western Corridor / Grumeti)

Location: Western Serengeti corridor, Grumeti River area

What you see: Rains ease. The western corridor has excellent game viewing, green scenery, and dramatically fewer tourists than any other month. Grumeti River crossings continue. May is one of Africa's best-kept safari-value secrets.

Crowd level: Low.

Price: Low–shoulder season. Excellent value.

June — Dry Season Begins (Western to Northern Serengeti)

Location: Western corridor transitioning north toward the Mara River

What you see: The dry season arrives. Vegetation thins and animals become easier to spot. The migration herds are consolidating and moving north. Grumeti crossings continue through early June. The northern Serengeti (Kogatende, Lamai) begins to receive its first migration groups. Excellent month for photographers — good light, green scenery transitioning to gold, and fewer vehicles than July.

Crowd level: Moderate, rising through the month.

Price: Shoulder season. Rising from mid-month.

July — Mara River Crossings Begin (Northern Serengeti)

Location: Northern Serengeti — Kogatende, Lamai, Mara River

What you see: The Mara River crossings are the most dramatic single wildlife event in Africa. Herds of 10,000–50,000 wildebeest mass on the southern bank, working up the nerve to cross. When they go, they go — thousands of animals churning through a river filled with 4-metre Nile crocodiles. The spectacle can last minutes or hours. Our guides have been reading the river for decades. We position clients at the right crossing points and wait as long as it takes.

Crowd level: High and rising through the month.

Price: Peak season. Book camps 3–6 months in advance.

August — Peak Crossing Season (Northern Serengeti / Masai Mara)

Location: Northern Serengeti and Masai Mara, Kenya

What you see: The apex of the crossing season. The largest herds, the most frequent crossings, the highest predator density. Lions, leopards, and cheetahs position near crossing points to take separated, exhausted animals. August is also the most crowded month in the Serengeti — 30–40 vehicles at popular crossing points is common. Safaris Tanzania guides know the lesser-used crossing points and position clients away from the main crowds.

Crowd level: Very high.

Price: Highest of the year. Camps sell out. Minimum 4–6 month advance booking.

September — Late Crossings (Northern Serengeti)

Location: Northern Serengeti, beginning to return south

What you see: Crossings continue but become less frequent as the herds begin their southward return. Still excellent game density and strong predator sightings. Significantly fewer vehicles than August. September is underrated — the same crossing drama with more breathing room.

Crowd level: Moderate–high, but notably lower than August.

Price: High season, slightly below August peak.

October — Herds Return South (Central Serengeti)

Location: Central Serengeti, moving south

What you see: The final Mara crossings. The Serengeti is dry and wildlife concentrates at the few remaining water sources. The Seronera area has exceptional lion and leopard sightings as prey gathers at the river. October is one of the best months for predator viewing in the central Serengeti.

Crowd level: High but below August peak.

Price: High season.

November — Short Rains (Central to Southern Serengeti)

Location: Herds spread across central and southern Serengeti

What you see: Short rains trigger fresh grass growth across the Serengeti. The herds spread out across the ecosystem as the new growth draws them south. November is quiet, green, and excellent value — the Serengeti turns lush and under-visited. The first zebra and wildebeest groups arrive on the southern plains.

Crowd level: Low. One of the least-visited months.

Price: Shoulder season. Good value.

December — Southern Serengeti (Pre-Calving)

Location: Southern Serengeti, Ndutu and surrounding plains

What you see: Herds concentrate in the southern plains as the short grass draws them south. The first heavily pregnant wildebeest arrive. Calving begins in late December and builds through January. December has excellent wildlife density, relatively compact herds, and — in the first half — fewer visitors than the Christmas–New Year holiday rush.

Crowd level: Medium. Holiday season brings more visitors from mid-December.

Price: High season, rising through December.

Two Migration Experiences: Our Recommendation

Option A — River Crossings (July, August, or September): The iconic migration image. 50,000 wildebeest crossing a crocodile-filled river is one of the most dramatic scenes in nature. The trade-offs: peak prices, peak crowds, and the reality that you may wait 2–3 days at the river without a crossing. When it happens, it is unforgettable. Book 4–6 months in advance and plan a flexible itinerary.

Option B — Calving Season (January or February): Our top recommendation for most first-time safari travellers. The calving spectacle — 8,000 calves per day, every predator in the ecosystem active in daylight — is sustained over days rather than concentrated in minutes. Crowds are dramatically lower. Prices are 20–30% below peak. Read our full calving season guide for detail on the Ndutu experience.

How to Book Around the Migration

The migration moves in a predictable loop but not a predictable calendar. The wildebeest follow the grass, which follows the rain. No one — not even our guides who have watched these herds for 40+ years — can guarantee a crossing on a specific day.

What we can guarantee: the right vehicle, the right guide, the right positioning, and the patience to wait. A private safari with a dedicated guide gives you the flexibility to stay at a crossing point all day if needed. Group tours cannot do this — their schedules do not allow it. See our comparison of private vs group safari for the full picture.

Frequently Asked Questions

When is the best time to see the Great Migration river crossings?

The Mara River crossings are most frequent and most dramatic in July, August, and September. August has the largest herds and most crossings, but also the most vehicles. September offers excellent crossings with fewer crowds and lower prices. Book your camp 4–6 months in advance for any of these months.

What is the difference between the Serengeti and Masai Mara for migration viewing?

The herds cross between the Serengeti (Tanzania) and Masai Mara (Kenya) continuously from June to October. The Serengeti side is significantly larger, less crowded in the northern sector, and offers more diverse accommodation options. The Masai Mara is smaller and the crossings can be more concentrated. Both are excellent. See our full Serengeti vs Masai Mara comparison.

Is the calving season better than the river crossings?

They are different experiences, not comparable ones. The crossings are dramatic in concentrated bursts — extraordinary when they happen but unpredictable in timing. The calving season is sustained over days — you will see multiple predator-prey interactions every day for as long as you are there. For most first-timers with flexibility on dates, we recommend the calving season for its consistency and value.

How much does a migration safari cost with Safaris Tanzania?

A 7-day migration safari with Safaris Tanzania starts from approximately $1,872 per person in the mid-season (January–February, November), rising to approximately $2,496–$2,912 per person in peak season (July–September, December). All quotes are all-inclusive — park fees, accommodation, private vehicle, and guide. No hidden charges. Get your exact quote in 3 minutes.

Can I see the migration on a 5-day safari?

A 5-day safari can reach the northern Serengeti for crossing season or Ndutu for calving season, but the travel time from Arusha (3–4 hours to Serengeti central, 5–6 hours to northern sector) means two full days are spent in transit. For the calving season, a 5-day works if you fly into Ndutu or a nearby airstrip. For the crossings, we recommend 7 days minimum to allow proper time at the crossing points without feeling rushed.
