The best 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 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.
