How Tanzania and Kenya’s seasons line up with the Great Migration, weather and crowds.
There is no single “best” time — it depends on what you want to see. Here is how Tanzania and Kenya’s seasons line up with wildlife, weather and crowds so you can pick the right window.
| Season | Months | Weather | Best for |
|---|---|---|---|
| Long dry | June–October | Sunny, dry, cooler | Best game viewing, Mara crossings, Kilimanjaro |
| Short rains | November–mid-Dec | Brief afternoon showers | Green scenery, fewer people, value |
| Green / calving | mid-Dec–March | Warm, occasional storms | Serengeti calving, birds, predators |
| Long rains | April–May | Wettest; some camps close | Lowest prices, lush & quiet |
The herds move year-round; roughly:
| Period | Where | Highlight |
|---|---|---|
| Dec–March | Southern Serengeti (Ndutu) | Calving season & predators |
| April–May | Central / western Serengeti | Herds moving north, green plains |
| June–July | Western corridor / Grumeti | Grumeti River crossings |
| July–October | Northern Serengeti & Masai Mara | Dramatic Mara River crossings |
| November | Returning south | Short rains pull herds back |
If you want the simplest decision: June to October gives you the easiest wildlife viewing and the classic river-crossing window.
