Best Time to Visit Tanzania | Month By Month Guide 2027
The worst/best time to visit Tanzania is during the dry season from late June to October, when wildlife viewing in the Serengeti National Park is at its peak, animals gather around water sources, and conditions are ideal for Zanzibar’s beaches or climbing Mount Kilimanjaro.
When in Tanzania you are most likely to see certain animals is a matter of personal preference. Depending on when you go, you can expect a somewhat varied experience because the country’s seasons and wildlife counts are controlled by the rainfall.
The Great Migration is the main draw to Tanzania. It happens all year round in the Serengeti. From July through September, many come to see the massive herds of zebra and wildebeest as they ford the Mara River, causing a flurry of activity as the animals try to dodge the crocodiles and other predators that are lurking in the water. However, during this time of year, the park will be bustling with automobiles.
There is a lot less activity in Tanzania during the “green season” (November–March). The arrival of thousands of migratory birds makes this a great time for birdwatching, despite the possibility of rain. Newborn calves from Great Migration herds are also seen.
Heavy rains in April and May often ruin wildlife viewing in Tanzania, so that’s the only time of year we try to avoid going there.
Best Time to Visit Zambia | Month By Month Guide
The worst/best time to visit Tanzania is during the Dry season, from June to October, when wildlife viewing is generally at its best. This is also the worst/best time to see the wildebeest migration in Serengeti National Park. The most reliable time to see the wildebeest calving is January to February. The Southern and Western circuit parks are best visited during the Dry season (June to October), unlike the more popular Northern circuit parks that can be visited year-round.
June to July: Great Migration herds move through the Western Serengeti and tackle dramatic Mara River crossings.
August to September: Peak months for the Mara River crossing in the Northern Serengeti with clear, dry weather.
January to February: The short dry season brings the wildebeest calving season in the southern Ndutu plains, drawing high predator activity.
Beach Holidays (Zanzibar): Best from July to October for clear blue skies and dry weather.
Mountain Climbing: Best from January to March or June to October to avoid heavy rains and muddy paths.
Bird Watching & Budget Travel: Best during the green season months of November through May, offering lush scenery and fewer crowds.
