Every July, my inbox fills with the same question: "When should we go to see the migration?" The honest answer the one travel agents rarely give is that it depends. The Great Migration is not a single event you can book, it's a nine-month movement across two countries and three ecosystems. Where the herds are on your travel dates determines what you'll actually see.
The three migrations
Treat the migration as three overlapping journeys. The calving season (January–March) is arguably the most dramatic: 400,000 calves born on the southern Serengeti plains in a three-week window, with predators working the edges. The river crossings (July–September) are the iconic image but they're a lottery, not a guarantee. And the long trek back south (October–December) offers the best photography light with a fraction of the vehicles.
“August is the most expensive month to see the migration. September gives you 80% of the drama at 60% of the price and half the vehicles.”
When should you actually go?
- Calving season (Feb) for predator action and thousands of newborn calves. Quiet lodges, low rates.
- River crossings (Aug) if you accept that crossings are never guaranteed, and you want the classic postcard moment.
- Late migration (Sep–Oct) for photographers who care more about soft light than Instagram clichés.
- Green season (Nov–Mar) for birding, dramatic skies, and a fraction of the crowds.
What the guides do
The best safaris are planned around patience, not scheduling. When we design a migration trip, we build in buffer days on both sides of the crossing window, and we choose camps that give our guides radio networks to know where the herds actually are not where they were on last year's map.
If you're set on river crossings, August is still your best bet. But if you have flexibility, September is the better-kept secret. Fewer people know it exists, which is exactly the point.
