Complete month-by-month Great Migration calendar for 2026-2027. Know exactly where the wildebeest herds will be and when to witness river crossings.
The Great Migration is Earth most spectacular wildlife event, with over 1.5 million wildebeest, 200,000 zebras, and 500,000 gazelles making their annual circuit through the Serengeti-Mara ecosystem. This guide provides a detailed month-by-month breakdown for 2026 and 2027, based on our 20+ years of tracking migration patterns.
Understanding the Great Migration Cycle
The migration is driven by the search for fresh grazing and water. According to research from the Tanzania National Parks Authority (TANAPA), the herds follow ancient routes that have remained largely unchanged for thousands of years.

Best Time for River Crossings
The Mara River crossings are the migration most dramatic moments. Based on our field data:
- Primary Crossing Season: Late July through September
- Peak Activity: August typically offers the most crossing opportunities
- Grumeti Crossings: June offers excellent, less-crowded alternatives
2027 Migration Predictions
While we are still collecting data, early climate models suggest 2027 may see slightly earlier rains, potentially shifting the migration 2-3 weeks ahead of the typical schedule. We will update this guide as more information becomes available.
