January to March – Southern Serengeti and Calving Season
The migration begins the year in the southern Serengeti plains, particularly around the Ndutu region and the Ngorongoro Conservation Area. During this period, nutrient-rich grasses flourish after the seasonal rains, attracting massive herds of wildebeest, zebras, and gazelles.
This is the peak calving season, with hundreds of thousands of wildebeest calves being born. The synchronized births overwhelm predators, giving newborns a higher chance of survival. Lions, cheetahs, and hyenas are highly active, creating thrilling wildlife viewing opportunities. Safari travelers visiting at this time can witness dramatic predator-prey interactions against the backdrop of lush green plains.
April to May – Central Serengeti and Migration Movement
As the southern plains begin to dry, the herds start moving northward toward the central Serengeti. This stage is marked by long lines of wildebeest traveling across rolling savannahs, open woodlands, and scattered kopjes.
The central Serengeti provides a transitional habitat with sufficient grazing and water sources. Wildlife sightings remain frequent, though herd densities are slightly lower than during calving season. This period offers quieter safari experiences with fewer crowds, ideal for travelers seeking peaceful wildlife observation and photography opportunities.
June to July – Western Corridor and Grumeti River Crossings
By mid-year, the herds reach the western corridor of the Serengeti, encountering the Grumeti River. This is the first major river crossing in the migration cycle, where crocodiles and strong currents challenge the moving herds.
The Grumeti River crossings are intense and dramatic. Wildebeest navigate the waters in large groups, while predators like crocodiles exploit vulnerable animals. Photographers and wildlife enthusiasts are drawn to this stage for the opportunity to capture powerful action shots of survival and instinct.
This period is ideal for travelers looking to witness river crossings without the heavy crowds that arrive later in the northern migration.
July to October – Northern Serengeti and Mara River Crossings
The migration reaches its most famous stage as the herds approach the Mara River and cross into the Maasai Mara in Kenya. This period is considered the pinnacle of the Great Migration, with thousands of animals plunging into crocodile-infested waters.
River crossings during this time are both dangerous and spectacular. Wildebeest, zebras, and gazelles face strong currents and lurking predators. Lions, cheetahs, leopards, and hyenas patrol the plains, creating scenes of raw wildlife drama.
August and September are peak months for river crossings. Safari travelers and wildlife photographers often schedule visits during these months to maximize the chance of witnessing this iconic event.
October to November – Northern Mara and Return Journey
After the river crossings, herds spread across the Maasai Mara and begin grazing on lush grasses in Kenya’s northern plains. As rains return to Tanzania, the animals gradually start moving southward back toward the Serengeti.
This period marks the beginning of the return migration, with herds preparing to complete the annual cycle. Wildlife viewing remains excellent, with predator activity still high and large herds visible across open grasslands.
Visitors during this period can experience abundant wildlife without the crowds associated with peak river crossing months.
December – Southern Serengeti Preparation
By December, the herds begin returning to the southern Serengeti, completing the circular migration. Grass growth in the southern plains is renewed by the onset of seasonal rains, providing fresh grazing for the wildebeest, zebras, and gazelles.
This stage sets the scene for the next year’s calving season. Travelers visiting in December can observe large herds regrouping, giving insight into herd dynamics and preparation for the birth of the next generation.
Safari experiences in December often combine wildlife observation with vibrant landscapes, as the plains turn green and waterholes fill, attracting diverse species.
Using the Migration Calendar for Safari Planning
The Great Migration Calendar allows travelers to plan trips according to specific wildlife interests. Calving enthusiasts should aim for January to March in the southern Serengeti, while river crossing aficionados should target August and September in the Maasai Mara.
Other months offer unique experiences as well. April to May is perfect for less crowded central Serengeti safaris, June to July offers dramatic Grumeti River action, and October to December allows travelers to enjoy the southern plains with vibrant landscapes and large, regrouping herds.
Understanding the migration calendar also aids in photography and wildlife observation. Knowing where the herds are likely to be each month helps travelers position themselves for optimal viewing and ensures a rewarding safari experience.
Factors Affecting the Migration Timing
While the migration follows a general pattern, several factors can influence its timing.
Rainfall patterns: The growth of fresh grasses drives herd movement. Early or late rains can shift migration stages forward or backward by weeks.
Water availability: Rivers and seasonal ponds play a critical role in determining where herds congregate and cross. Dry conditions may delay crossings, while high water levels increase the challenge and spectacle of river events.
Predator pressure: The presence of lions, cheetahs, leopards, and hyenas can influence herd movement. Animals may temporarily avoid areas with high predator activity, subtly altering migration timing.
Human activity and conservation zones: Protected areas like the Serengeti and Maasai Mara are crucial for maintaining migration corridors. Development or restricted access outside these zones can impact the flow of herds.
