Seasonal movement
The Great Migration is a year-round circle, not a two-week event. Southern Serengeti calving is usually roughly December–March; western corridor and Grumeti crossings often around May–July; northern Mara River drama typically July–October. Camp placement and flight logistics matter more than chasing a viral clip.
Great Migration
Each year, roughly 1.5 million wildebeest, hundreds of thousands of zebra and accompanying gazelles move through the Serengeti–Mara ecosystem in search of fresh grazing and water.
The route is continuous, not a single event. Rainfall and grass growth decide where the densest herds gather — so calendars describe typical patterns, not fixed dates.
The migration is a year-round loop. Calves are typically born on the short-grass plains of the southern Serengeti and Ndutu region early in the year. As rains and grazing shift, columns move through central Serengeti and often into the Western Corridor before pressing north.
In the northern Serengeti and Mara, herds may cross the Mara River when grazing and water levels align. Later, short rains generally draw animals south again. Any month-by-month guide is a planning tool — herds can pause, reverse or use different crossing points.
Use this seasonal guide as a planning map. Nature does not follow a fixed timetable — rainfall can advance, delay or redirect the herds.
December – March
Herds typically concentrate on southern short-grass plains. Calving often peaks around February, bringing predator attention. Conditions still depend on rainfall and grazing quality.
April – May
As the long rains settle in, herds generally push north and west. Columns can be dispersed; roads may be softer. This can be quieter and green, with different photographic mood.
May – July
Many years see herds use the Western Corridor, with possible Grumeti River activity. Timing varies widely — treat crossings as possible, not scheduled.
July – October
Herds often reach northern Serengeti and Kenya’s Mara. Mara River crossings may occur across this window, but not every day and not always at the same ford.
October – November
Short rains generally encourage southward movement through northern and central Serengeti. Transition weeks can feel unpredictable — and rewarding when herds are still dense.
On the southern plains, tens of thousands of calves are typically born over a short window. Predators follow. It is dramatic — and weather-dependent. We plan Ndutu or southern Serengeti stays when your dates align with this phase, and we say so clearly when they do not.
The Western Corridor offers a different migration chapter: riverine woodland, the Grumeti, and often fewer vehicles than the northern river drama. Crossings here can be smaller and more scattered.
Northern Serengeti camps near the Mara River put you in position for possible crossings while still offering excellent general game when herds are elsewhere. Flexible night placement matters more than a single “crossing day”.
River crossings happen when herds decide conditions are right — water levels, crocodile density, leading animals and grazing on the far bank all play a role. They can occur at dawn, midday or not at all for days. We plan enough nights in the right region to improve your odds without promising a spectacle.

View safariIt is the continuous movement of wildebeest, zebra and other grazers around the Serengeti–Mara ecosystem, driven by rainfall and fresh grass.
It depends what you want: calving in the south early in the year, or northern river drama later. There is no single best month for every traveller.
Calving is typically associated with January–March on the southern Serengeti and Ndutu plains, often peaking around February — subject to rainfall.
Mara River crossings are most often associated with July–October, but they are irregular. Grumeti activity may occur earlier in the Western Corridor.
No. Wildlife and crossings cannot be guaranteed. We plan for strong probabilities and communicate uncertainty clearly.
Both belong to one ecosystem. Date and herd location decide which side makes more sense — sometimes a Tanzania-only or Kenya-only plan is cleaner.
For a focused migration chapter, several nights in one well-chosen region usually beats a rushed circuit. We tailor length to your dates and interests.
