January to March: The Calving Season in Ndutu (Southern Serengeti) This is the season of new life. In the southern Serengeti and the Ndutu plains, thousands of wildebeest give birth to their young between January and March. The landscape is lush and green, and predators such as lions and cheetahs lie in wait, creating intense wildlife action. This period is ideal for travelers who want to witness the emotional intensity of life and death on the plains, all in a relatively quiet and scenic setting.

April to May: Migration Moves Northwest As the rains arrive, the herds begin their journey northwest through the central Serengeti. This period, while considered part of the low season, offers excellent value with fewer tourists, dramatic storm skies, and incredible photographic opportunities. You may also benefit from discounted mid-range safaris during these months.

June to July: Grumeti River Crossings This is one of the most thrilling times to be in the Serengeti. Between June and July, the herds gather at the Grumeti River. While not as famous as the Mara River crossings, Grumeti crossings still deliver adrenaline-pumping moments as wildebeests face off against hungry crocodiles. This time also marks the start of the dry season, with pleasant weather and clearer roads. A Great Migration Safari in this window is perfect for travelers wanting classic safari conditions.

August to October: Mara River Crossings in Northern Serengeti By August, the migration reaches the northern Serengeti, bordering Kenya’s Maasai Mara. This is when the dramatic Mara River crossings take place — chaotic, perilous, and breathtaking to witness. Thousands of animals attempt to cross crocodile-infested waters, often resulting in tragic yet gripping scenes of nature’s raw power. Book early, as this is peak season. You can explore our Northern Serengeti Safari Itinerary for trip ideas.

November to December: Return to the South As short rains return, the herds begin their long trek south, moving through the eastern corridor of the Serengeti. Though quieter, this shoulder season offers a more intimate safari experience. The plains start to turn green again, and anticipation builds for the next calving season. For travelers who want a less-crowded adventure, this is the time to enjoy a more relaxed pace.
