When Is the Best Time to See the Great Migration?
The Great Wildebeest Migration is one of the most awe-inspiring natural spectacles on Earth — a continuous, year-round movement of over 1.5 million wildebeest, accompanied by zebras and gazelles, across the vast plains of Tanzania’s Serengeti and Kenya’s Maasai Mara. It’s a story of survival, instinct, and the rhythm of nature — where life, birth, and drama unfold daily.
Witnessing this migration is a dream for many travelers, but because the herds move throughout the year, timing your visit right is key to catching the best action. Here’s a month-by-month guide to help you plan your safari for the experience of a lifetime.
December to March – Calving Season in Southern Serengeti (Ndutu Area)
From late December through March, the herds gather on the short grass plains of southern Serengeti, particularly in the Ndutu and Kusini regions. The lush green pastures here provide ideal conditions for birthing season — over half a million wildebeest calves are born in just a few weeks, usually between January and February.
This period is filled with tender moments as newborn calves take their first steps — but also intense drama, as predators like lions, cheetahs, and hyenas take advantage of the abundance of prey.
If you love witnessing the circle of life and want exceptional photographic opportunities, this is one of the most rewarding times to visit Tanzania.
April to June – The Long Journey North
As the rains ease, the herds start their long trek northwest towards the Serengeti’s central and western corridors. April and May mark the beginning of the great movement, with animals spreading out across the plains in search of fresh grazing.
The scenery is lush and green, and while rains may cause some muddy roads, it’s an excellent time to enjoy fewer crowds and lower prices. In June, the wildebeest start gathering around the Grumeti River, where the first river crossings occur. Here, enormous crocodiles lie in wait — creating thrilling, once-in-a-lifetime scenes of raw wildlife power.
July to September – River Crossings in Northern Serengeti
This is the most dramatic and popular stage of the Great Migration. Between July and September, the herds reach the northern Serengeti and approach the Mara River, where they face their greatest challenge: crossing the crocodile-infested waters to reach Kenya’s Maasai Mara.
The Mara River crossings are unpredictable, often happening without warning. Thousands of wildebeest may hesitate for hours before one brave animal leads the charge — followed by a thundering rush of hooves, splashing water, and the fight for survival.
If witnessing this heart-pounding moment is on your bucket list, plan to visit the northern Serengeti (Kogatende or Lamai regions) between late July and early October. Early bookings are essential, as this is peak safari season in Tanzania.
October to November – Return to the South
As the rains return to the Serengeti, the herds begin their southward journey, leaving the Maasai Mara and heading back through the eastern and central Serengeti. The cycle continues — migration never truly stops.
This is a quieter time to visit, with fewer tourists and beautiful post-rain scenery. You’ll still find large herds on the move, as they make their way back toward the Ndutu plains, ready to start the calving season once again.
Tips for Planning Your Great Migration Safari
Book early: Camps in migration hotspots fill up quickly during peak months.
Choose your region wisely: The migration moves constantly — work with a safari expert to match your travel dates to the right area.
Consider a mobile camp: These move with the herds, ensuring you’re always close to the action.
Bring good gear: Binoculars, cameras, and protective clothing are essential.
In Summary
The Great Migration is a year-round event, but the best time to see the most dramatic scenes depends on what you want to experience:
Calving and predator action: January–March (Southern Serengeti, Ndutu).
First crossings and lush landscapes: May–June (Western Serengeti).
Epic Mara River crossings: July–September (Northern Serengeti).
Return migration: October–November (Eastern Serengeti).
No matter when you visit, Tanzania offers unmatched opportunities to witness nature’s most powerful story an endless journey of life, struggle, and renewal across the golden plains of Africa.
