The best time to go on a safari depends on your wishes and expectations. Tanzania offers great opportunities year-round. The Great Migration usually happens November to June, with the exact timing depending on the species and distinct herds. The dry season from June to October is also great for wildlife watching when animals congregate around water sources, making it easier to spot them.
June through October are the most popular months for safari as they offer pleasant weather with lower humidity. You can expect rain torrents from March to May and occasional short rainstorms from November to December. Rain can make the roads muddy and occasionally inaccessible.
