Few spectacles on Earth rival the sheer scale of the Great Migration. Every year, over 1.5 million wildebeest, accompanied by hundreds of thousands of zebras and gazelles, form an endless, thundering column across the East African plains. Driven by ancient instincts to follow the rains and fresh grazing, this continuous journey is the ultimate wildlife experience.
However, because the migration is a year-round, circular movement rather than a single fixed event, timing and location are everything. If you are planning an expedition to witness this natural wonder firsthand, understanding the annual cycle is essential.
As local safari specialists based in Arusha, Tanzania, we’ve mapped out the year-round journey of the herds so you can be in the right place at the right time.
The Annual Migration Cycle: Month by Month
While the herds are constantly on the move, their journey follows a generally predictable seasonal pattern across the Serengeti ecosystem and Kenya’s Maasai Mara.
1. January to March: The Calving Season (Southern Serengeti / Ndutu)
- Where they are: The short-grass plains of the southern Serengeti and the Ngorongoro Conservation Area (Ndutu region).
- The Highlight: This is one of the most emotional and dramatic times of the migration. Up to 8,000 wildebeest calves are born every single day over a concentrated two-to-three-week window.
- The Action: The nutrient-rich grasses provide ideal nourishment for mothers and newborns. Naturally, this massive concentration of vulnerable calves attracts high numbers of predators. Expect thrilling, high-action sightings of lions, cheetahs, leopards, and hyenas.
2. April to May: The Long Rains & The Move North (Central & Western Serengeti)
- Where they are: Moving gradually northwest through the central Serengeti and the Western Corridor.
- The Highlight: As the long rains transform the landscape into lush, emerald-green savannahs, the herds begin dispersing and marching northward.
- The Action: While the weather can be wet, this period offers incredible dramatic lighting for photography and complete solitude away from heavy tourist crowds.
3. June to July: The Rut & The Western Corridor Crossings (Grumeti River)
- Where they are: Western Serengeti, approaching the Grumeti River.
- The Highlight: As the dry season takes hold, the herds consolidate and push toward the permanent waters of the western corridor.
- The Action: Here, the herds face their first major aquatic obstacle: the Grumeti River. While smaller than the famous Mara River crossings, the Grumeti features massive crocodiles and deep channels, providing a thrilling preview of the river-crossing drama to come. This period also marks the rut (mating season), characterized by intense head-butting clashes between dominant males.
4. August to October: The Peak Mara River Crossings (Northern Serengeti)
- Where they are: The remote Lamai and Lobo regions of the northern Serengeti, crossing back and forth across the border into Kenya’s Maasai Mara.
- The Highlight: This is the iconic peak of the migration. Millions of animals press up against the banks of the mighty Mara River, hesitating before plunging into waters teeming with massive Nile crocodiles and strong currents.
- The Action: Witnessing a river crossing is an unforgettable, heart-pounding experience. There is no set schedule—a crossing can happen at any moment, requiring patience, expert guide positioning, and a bit of luck.
5. November to December: The Return South (The Lobo & Loliondo Plains)
- Where they are: Northeastern and eastern Serengeti, heading back south.
- The Highlight: As the short rains arrive in November, refreshing the eastern and southern plains, the herds begin their long trek southward.
- The Action: The columns spread out across the landscape, moving with renewed energy as they chase the fresh green shoots back toward the calving grounds where the cycle began.
