Tanzania Seasons Overview: When to Go for the Best Safari
Tanzania has two main seasons: the dry season (June to October) and the green/wet season (November to May). Each offers unique advantages depending on what you want to see and experience. The dry season is generally considered the best time for wildlife viewing, while the green season offers lush landscapes, fewer crowds, and excellent birdwatching.
"The best time to visit Tanzania depends entirely on what you want to experience — the drama of the Mara River crossings, the miracle of calving season, or the solitude of the green season with its migratory birds." — Tanzania Travel Experts
Dry Season
June - October
- ✓ Best wildlife viewing
- ✓ Little to no rain
- ✓ Animals gather at water sources
- ✓ Mara River crossings (Aug-Oct)

Green Season
November - May

Dry Season (June - October): Peak Safari Season
The dry season is Tanzania's most popular time for safaris — and for good reason. With little to no rainfall, vegetation thins out, and animals gather around permanent water sources like rivers and lakes. This makes wildlife much easier to spot. The dry season also coincides with the most dramatic phase of the Great Migration: the Mara River crossings (August-October).
- Weather: Sunny days, cool nights (especially June-July), virtually no rain
- Temperatures: 15-28°C (59-82°F) depending on altitude
- Wildlife viewing: Excellent — best of the year
- Crowds: Peak season — book 6-12 months in advance
- Best for: Serengeti migration (river crossings), Ngorongoro Crater, Tarangire elephants
Green Season (November - May): Low Season Bargains
The green season (also called the wet season) offers a completely different but equally rewarding experience. The landscape turns lush and green, flowers bloom, and migratory birds arrive from Europe and Asia. This is also calving season (January-February) when over 8,000 wildebeest calves are born daily in the southern Serengeti — attracting intense predator action.
- Weather: Afternoon showers, morning sunshine. Short rains (Nov-Dec), long rains (March-May)
- Temperatures: 18-30°C (64-86°F) — warmer and more humid
- Wildlife viewing: Good to excellent (calving season is spectacular)
- Crowds: Low to moderate — best time for budget travelers
- Best for: Calving season (Jan-Feb), birdwatching, lower prices, fewer tourists
