January to February:
In January, the wildebeest calving season in Serengeti begins. Thousands of wildebeests are born everyday so predator action is expected in almost every turn. Wildlife viewing is also excellent in Ngorongoro Conservation Area as well as Lake Manyara National Park during these months.
Migration herds in Serengeti remain in the southern region of the park while European migratory birds arrive in the southern regions of the country, i.e. Selous Game Reserve. “Long rains” also start this month.
April to May:
This is the peak of the wet season (long rains). Vegetations become lush thereby affecting wildlife viewing and as a result, most properties and parks in the southern circuit (Katavi, Mahale, Selous, Ruaha) shuts down. The good news during these months is, prices usually dive deep down.
The dry and hot season commences. There is less vegetation and so it is easier to spot animals sauntering around and gathering in waterholes and rivers. Also, since there is little to no rain, there will be less mosquitoes around.
July to October:
These months are deemed the best time to witness the Great Migration, Weather-wise, it’s perfect: hot and sunny during the day and cold during the evenings. It is also not just the perfect time to see the wildebeest migration in the Serengeti or to visit other northern circuit safari parks. It is also the perfect time to visit the southern circuit safari parks like Ruaha, Selous, Gombe and Katavi.
November to December:
Migratory birds arrive and so it’s perfect for birdwatching. Migration herds are also on their way back to the southern part of Serengeti. Humidity starts to climb up during these months and “Short rains” happen (mostly short afternoon showers). In a nutshell, it is relatively good and to some extent excellent to visit any park or reserve in the country during this time.
