The migration traditionally follows the rains to take advantage of the new grasses on the plains of the Serengeti and Maasai Mara. (Please Click here for Migration Map) Theoretically, if traditional weather patterns occur annually, the following is a basic idea of how the migration moves throughout the year:
Late December/ Early January – Ndutu Region, Tanzania:Traditionally this is when the calves are born. The migration remains sedentary until April when the calves are strong enough to start moving north.
Early April/ May/ June – Serengeti, TanzaniaThe migration begins moving North-West following the ‘long rains’ across the Serengeti plains towards the Western Corridor and the Grumeti River.
June/ July – Western Corridor, TanzaniaThe animals gather in the Western Corridor
August/ September – Maasai Mara, KenyaThe migration crosses the Grumeti River and moves North-East into the Northern Steppes of the Maasai Mara
October/ November/ Early December – Maasai Mara, Kenya/ Northern Tanzania/ SerengetiAs the short rains begin in Northern Tanzania the migration begins to move South, back into the Kleins/ Lobo region of the Serengeti. From here they follow the rains through to Seronera and end up at Ndutu for the calving season.
Due to the fact that the migration follows the rains there is no hard and fast rule as to where the animals will be and when. Often the animals split into two groups as they move, resulting in one group moving on the Western side and another group moving on the Eastern side of the Serengeti finally meeting up at Ndutu or in the Mara. Viewing of the migration can not be guaranteed.
