The Great Migration is one of the most spectacular wildlife events on Earth. Every year, over 1.5 million wildebeest, accompanied by hundreds of thousands of zebras and gazelles, undertake a massive, continuous journey across the Serengeti-Mara ecosystem in search of fresh grazing and water. Timing your visit to witness this incredible spectacle is key, as the herds' location changes dramatically throughout the year.
This guide breaks down the migration patterns month-by-month, helping you plan the perfect safari to witness the drama unfold.
Understanding the Migration Cycle
Contrary to popular belief, the Great Migration is not a single event but a continuous, year-round cycle driven by rainfall and the growth of new grass. The herds are constantly on the move, but certain times of year offer more predictable and dramatic viewing opportunities.
December to March: Calving Season in the Southern Serengeti
Location: Southern Serengeti (Ndutu area) and Ngorongoro Conservation Area.
What to Expect: This is the calving season. From late January through February, around 8,000 wildebeest calves are born daily. The southern plains are lush and green, attracting massive herds and the predators that follow them. This is an excellent time for witnessing predator-prey interactions (lions, cheetahs, hyenas) and seeing adorable newborns.
- Pros: High concentration of herds, incredible predator action, beautiful green landscapes.
- Cons: Can be busy in popular areas. Short rains may still occur in December.
April to May: The Northward Trek Begins
Location: Moving from the Southern Serengeti through the central and western corridors.
What to Expect: As the rains end and the southern plains dry out, the herds begin their long trek north. The migration becomes more spread out. This is the long rainy season (April-May), meaning fewer tourists and lower rates, but some camps close and roads can be challenging. The landscape is incredibly lush and beautiful.
- Pros: Low season rates, fewer crowds, stunning green scenery.
- Cons: Heavy rains possible, some camps closed, animals more dispersed.
June to July: The Grumeti River Crossings
Location: Western Serengeti, Grumeti River area.
What to Expect: The herds gather on the banks of the Grumeti River, preparing for one of the first major river crossings. While the Grumeti crossings are less dramatic than the Mara (fewer crocodiles), they still offer thrilling wildlife viewing. The herds are more concentrated as they push north.
- Pros: Dramatic river crossings begin, good game viewing.
- Cons: Crossings can be sporadic; not as predictable as the Mara.
July to October: The Mara River Crossings (Peak Season)
Location: Northern Serengeti and Maasai Mara (Kenya).
What to Expect: This is the peak migration season and the most dramatic period. The herds mass on the banks of the Mara River, and the crossings are intense, chaotic, and fraught with danger from massive Nile crocodiles. Witnessing a Mara River crossing is a bucket-list wildlife experience. The herds typically spend July-October in the Northern Serengeti/Mara region.
- Pros: Most dramatic river crossings, peak wildlife concentration in the north.
- Cons: Peak tourist season (higher prices, more crowds), especially in August and September.
November to December: The Southward Return
Location: Moving from the Maasai Mara back through the Northern and Eastern Serengeti towards the southern plains.
What to Expect: As the short rains begin in November, the herds start their journey south, following the fresh growth. The migration is more spread out again. This is a good shoulder season with fewer crowds and good game viewing as the herds make their way back to the calving grounds.
- Pros: Fewer tourists, good game viewing, lower rates.
- Cons: Short rains possible, animals more dispersed.
Planning Your Migration Safari
The "best" time to see the Great Migration depends entirely on what you want to witness. For calving and predator action, visit January-February. For the iconic river crossings, plan for July-October. For a quieter, greener experience, consider the shoulder seasons.
