When is the Great Migration in Africa? Month-by-Month Guide
The Great Wildebeest Migration is widely celebrated as one of the most breathtaking wildlife spectacles on Earth. Every year, over 1.5 million wildebeest, accompanied by roughly 200,000 zebras and hundreds of thousands of Thomson’s gazelles and elands, trek in a relentless 1,000-kilometer loop across the pristine wilderness of the Serengeti in Tanzania and the Masai Mara in Kenya.
It is an epic story of life, death, endurance, and rebirth—a drama played out against sweeping savannahs, treacherous river crossings, and relentless apex predators like lions, leopards, cheetahs, and giant Nile crocodiles.
If you are planning a bucket-list African safari with Nature Expert Adventures, your single most important question is likely: “When is the Great Migration in Africa, and when is the best time to see it?”
The short answer? The Great Migration is not a single, one-off event—it is a continuous, 12-month annual journey. The herds are constantly moving in response to seasonal rains and fresh pasture. No matter what month you travel, the migration is happening somewhere in East Africa.
In this ultimate guide, we break down the month-by-month calendar of the Great Migration, explain where the herds are throughout the year, and help you choose the ideal time for your dream safari.
At a Glance: The Great Migration Year-Round Cycle
Before diving into the detailed monthly breakdown, here is a quick overview of how the herds move across the Serengeti-Mara ecosystem:
- January – March: Southern Serengeti & Ndutu (Calving Season & High Predator Action)
- April – May: Central & Western Serengeti (The Long Rains & Moving Columns)
- June – July: Western Corridor & Grumeti River (First River Crossings)
- August – October: Northern Serengeti & Masai Mara (Dramatic Mara River Crossings)
- November – December: Eastern Serengeti & Return South (Short Rains & Rebirth)
Month-by-Month Great Migration Breakdown
To choose the perfect timing for your travel style, preferences, and safari goals, let’s explore what happens on the ground during each phase of this natural marvel.
1. January to March: The Calving Season (Southern Serengeti & Ndutu)
- Location: Ndutu Region, Ngorongoro Conservation Area, and Southern Serengeti Plains.
- Weather: Warm and generally dry, with occasional short showers.
What Happens During Calving Season?
As the calendar turns to January, the herds congregate in the nutrient-rich plains of the Southern Serengeti and Ndutu. The short rains of late autumn have transformed these dusty plains into a lush, green carpet rich in calcium and phosphorus—essential nutrients for pregnant wildebeest.
February marks the peak of the Calving Season. Over a concentrated two-to-three-week window, more than 8,000 wildebeest calves are born every single day! Within just 3 to 7 minutes of birth, a newborn calf is up on its feet, running alongside its mother to keep pace with the herd.
Why Visit Now?
- High Predator Action: The sudden influx of vulnerable newborn calves attracts Africa’s highest concentration of big cats and scavengers. You will see lions, cheetahs, leopards, hyenas, and jackals hunting actively on the open plains.
- Stunning Scenery: The sweeping grasslands of Ndutu offer phenomenal visibility for wildlife photography.
- Off-Road Driving: Unlike many parts of the Serengeti, off-road driving is permitted in parts of the Ndutu area under special guides, allowing for extraordinarily close wildlife encounters.
2. April to May: The Moving Columns (Central & Western Serengeti)
- Location: Central Serengeti (Seronera) moving toward the Western Corridor.
- Weather: The “Long Rains” (heavy seasonal rainfall).
What Happens During the Long Rains?
By April, the southern pastures have been grazed down to the roots, and the heavy spring rains arrive. The herds begin their long march north and northwest toward the Seronera Valley and Western Corridor.
Millions of animals form massive, single-file columns stretching as far as the eye can see, trekking across muddy plains and swollen streams.
Why Visit Now?
- The “Green Season” Advantages: While April and May bring rain, this period offers incredible advantages for savvy travelers. Rates for luxury lodges drop significantly, and tourist numbers hit their lowest point of the year.
- Exclusivity: You will often have vast stretches of the Serengeti all to yourself.
- Lush Landscapes & Birdwatching: The landscape blossoms into vibrant green hues, and migratory birds are present in full force.
3. June to July: The Grumeti River Crossings & The Rut
- Location: Western Corridor of the Serengeti and the Grumeti River.
- Weather: Transition from rain to the dry season; cooler mornings and pleasant afternoons.
What Happens at the Grumeti River?
As June arrives, the herds enter the Western Corridor and encounter their first major water obstacle: the Grumeti River. While not as steep or famous as the Mara River, the Grumeti River poses a mortal threat. It is home to massive, hungry Nile crocodiles that have been fasting for months in anticipation of this arrival.
June is also the mating season (the rut). The plains echo with the grunts of territorial bulls competing for mates, creating an energetic and noisy atmosphere across the valley.
Why Visit Now?
- Fewer Crowds than Peak Season: You can experience river crossings before the absolute peak crowd levels of August.
- Sensory Spectacle: Combining the drama of river crossings with the energetic mating rituals of the herds creates non-stop wildlife action.
4. August to October: The Iconic Mara River Crossings (Peak Season)
- Location: Northern Serengeti (Tanzania) and Masai Mara National Reserve (Kenya).
- Weather: Peak dry season; warm, clear days and chilly mornings.
What Happens at the Mara River?
This is the moment most people picture when they think of the Great Migration. Having pushed northward through the Serengeti, the herds reach the banks of the treacherous Mara River.
To reach the lush green pastures of the Masai Mara or Northern Serengeti, millions of animals must plunge into torrents of rushing water bounded by steep, muddy cliffs. Instinct drives them forward, even as giant crocodiles lurk below and lions wait on the opposite shore.
Crucial Insight: The herds do not simply cross once and stay on the other side. They frequently crisscross the Mara River back and forth between Tanzania and Kenya throughout August, September, and October, following localized rainfall patterns.
Why Visit Now?
- Unmatched Drama: Witnessing thousands of wildebeest leaping down 10-meter riverbanks into churning water is an adrenaline-fueled, unforgettable spectacle.
- Prime Big Game Viewing: Because conditions are dry, wildlife congregates heavily around remaining water sources, making game viewing exceptionally easy and rewarding.
5. November to December: The Return South (Eastern Serengeti)
- Location: Northern and Eastern Serengeti (Lobo, Mbuzi Mawe) heading back to Ndutu.
- Weather: The “Short Rains” (brief, refreshing afternoon showers).
What Happens During the Return Trek?
With the onset of the short rains in late October or early November, the herds smell fresh grass blooming in the south. They begin their steady trek back down through the eastern boundary of the Serengeti, passing through the Lobo area.
By late December, the wildebeest and zebras arrive back in the southern short-grass plains of Ndutu, coming full circle to prepare for another calving season.
Why Visit Now?
- Great Shoulder Season: November and early December offer fantastic wildlife sightings with fewer crowds before the holiday travel rush begins.
- Emerald Landscapes: The short afternoon rains refresh the air, settle the dust, and turn the grassy plains brilliant shades of green.

Why Tanzania is the Heart of the Migration?
While Kenya’s Masai Mara receives plenty of fame, over 90% of the Great Migration’s annual cycle takes place within Tanzania.
The Serengeti National Park spans nearly 15,000 square kilometers (5,700 square miles), providing the vast territory needed to sustain millions of grazing herbivores year-round. Choosing Tanzania as your base gives you front-row access to the calving grounds, the river crossings, and the sweeping open plains in every season.
Exploring Southern Tanzania’s Hidden Gems

Choosing Tanzania as your base gives you front-row access to the calving grounds, the river crossings, and the sweeping open plains in every season.
1. Ruaha National Park
For guests seeking raw, rugged landscapes far removed from tourist crowds, Ruaha National Park is an absolute must. As one of Tanzania’s largest national parks, Ruaha is famous for its massive elephant herds, dramatic baobab trees, and an extraordinary predator population—holding roughly 10% of the world’s remaining wild lions!
2. Selous Game Reserve (Nyerere National Park)
If you dream of exploring Africa by water, Selous Game Reserve (now largely incorporated into Nyerere National Park) offers an unrivaled safari experience. As a UNESCO World Heritage site, Selous features boat safaris along the mighty Rufiji River, where you can drift past wallowing hippos, sunbathing crocodiles, and rare African wild dogs along the banks.
Combining a high-energy Serengeti migration safari with the wild tranquility of Ruaha or Selous delivers the ultimate, well-rounded Tanzanian expedition.
Expert Tips for Planning Your Great Migration Safari
Planning a trip to witness the migration requires foresight and expert logistics. Keep these pro tips in mind:
1. Book 6 to 12 Months in Advance
Because river crossing season (August–October) and calving season (February) are immensely popular, luxury safari camps and boutique lodges in key locations fill up quickly. Secure your spot well ahead of time.
2. Choose Semi-Permanent or Mobile Tented Camps
To stay close to the action, consider staying in luxury mobile tented camps that relocate twice or thrice a year following the migration’s natural movement. This ensures you spend more time viewing wildlife and less time driving to reach the herds.
3. Embrace Flexibility
Nature follows its own rhythm, not human schedules. Rainfall patterns shift slightly from year to year, which can accelerate or delay river crossings by a few weeks. Working with experienced guides ensures you can adapt your daily game drives to real-time herd movements.
4. Pack the Right Gear
- Camera with a Telephoto Lens (at least 300mm): Essential for capturing distant river crossings and predator activity safely.
- High-Quality Binoculars: One pair per person will dramatically enhance your game-viewing experience.
- Layered, Neutral Clothing: Khaki, beige, and olive clothing blend into the bush. Avoid dark blue and black, which attract tsetse flies.
