On the Quest
“When is the Great Migration?” is a loaded question. The short answer is that the cyclical journey happens year round and never ends. The long answer is that it depends on what you are interested in seeing! Whether the focus is going on safari in Tanzania’s Serengeti, exploring the Ngorongoro Conservation Area or seeing a river crossing at the legendary Mara River, the the best time see the Great Migration depends on where and when you go.
December – March: The Ngorongoro Conservation Area & Calf Birthing
During this season, the Great Migration congregates at the Ngorongoro Conservation Area in Southern Tanzania to wolf down abundant short grass. This region is a UNESCO World Heritage Site, and boasts natural wonders like the Ngorongoro Crater, archaeology discoveries and remarkable biodiversity and wildlife. The Gondwana Ecotours Wildlife Safari in Tanzania travels to the Serengeti National park and Ngorongoro Crater to experience these natural wonders first hand!
This time also serves as preparation for the synchronized wildebeest calf birthing that occurs for a few weeks between late January and early March each year. An estimated 300,000 to 400,000 calves are born within a few weeks. Though predators claim the lives of several calves during this time, the real danger lies ahead in the form of disease, fatigue, or simply getting lost.
April – June: The Journey North & Grumeti River Crossing
Around April, when the food supply diminishes, the massive herd and the newly born wildebeest calves gradually start the journey Northwest toward Kenya. From March to May, heavy rains fall on the Serengeti, making travel difficult for humans and animals alike! The wildebeest use this time to begin mating for next year’s calving season.
By June, the wet season ends and the land begins to recover. At this point, the Great Migration amasses in a large crowd before making its first river crossing at the Grumeti River. This annual river crossing is a favorite safari spot, where travelers can see wildebeests, zebras, and other game fight for their lives against the current and the huge crocodiles awaiting their yearly feast.
July – November: The Mara River Crossing & Kenya’s Maasai Mara
After the animals feast on the available grass and water near the Grumeti, the herd moves onto the most iconic stop of the Great Migration, the river crossing at Mara River. Weather depending, this crossing can happen any time between early July to mid August. The crossing location and time cannot be pinpointed because it fluctuates each year. Herds may congregate in the thousands, then wander off to a different area along the river. When they finally do make the crossing, it is one of nature’s most savage phenomenons, as many weak, young, or unlucky animals lose their lives to crocs along the way.
The animals who make it through the journey alive reach their final destination, Kenya’s Maasai Mara around September, making it an excellent time for safari in the park. The wildlife only stays here for a few months, before turning around and heading south in October and November. This completes the annual route, as the animals head back to the green grazing pastures of the Serengeti.
For those wondering “When is the Great Migration?”, the true answer is imprinted in the genes of the 2 million wildebeest, zebra, and other animals that go along for the ride. Humans have to rely on history, maps, and weather patterns to guess where and when to see the Great Migration. Though elusive, this migration is a year round safari favorite.
