Tanzania’s climate varies widely across its regions and elevations, so timing your visit is key to making the most of your experience. For wildlife safaris — especially the chance to witness the iconic Great Migration in the Serengeti — the best time to visit is the dry season, from June to October. During these months, vegetation is sparse, and animals gather around water sources, making them easier to spot and photograph.
If your plans include a beach escape to Zanzibar, the dry season offers the most inviting conditions — sunny skies, calm turquoise waters, and excellent visibility for diving and snorkeling. The long rainy season, from March to May, sees fewer visitors and more affordable rates, but it can bring heavy downpours that make some roads and attractions harder to access.
For those planning to climb Mount Kilimanjaro, the most favorable months are January to March and June to October, when weather conditions are generally more stable. Even during these periods, trekkers should be prepared for cold temperatures and frosty nights at higher elevations, as the mountain’s alpine climate can be unpredictable.
