BEST SEASONS FOR GOING ON SAFARI:
The ideal time to visit Tanzania is during the Dry Season, from late June to October, when wildlife viewing is generally at its best. The wildebeest migration in the Serengeti is usually during June and July and the time to see the wildebeest calving is from late 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.
High Season: July to March (northern circuit parks; they get crowded), July to October (southern and western circuit parks; they don’t get crowded any time of the year)
Low Season: April and May (northern circuit parks still get quite a few visitors unlike the southern and western circuit parks, where many lodges close down). The scenery is green and beautiful; and low season means lower rates and less crowded parks.
Best Weather: June to October (Little to no rainfall). Animals are easier to spot since they concentrate around waterholes and rivers. There are fewer mosquitoes because there is little to no rain. Skies are clear and most days are sunny.
Worst Weather: March and April (Peak of Wet season)
Dry Season: June to October. Hot, but often dusty.
Best Months to see the Wildebeest Migration: June and July. August to September is the best time to see the wildebeest river crossings in northern Serengeti
January-February: is the time to see the calving in the southern Serengeti, and an excellent time to see predators in action.
Except for March, April and May, rains are mostly short afternoon showers and seldom interfere with your trip.
