Best time to visit the Zanzibar Archipelago
The dry season from June through to October is generally considered the best time to visit the Zanzibar Archipelago, which also coincides with the safari high season. You can expect clear, sunny skies, warm temperatures, and a lack of rainfall. As many visitors like to spend time on the beaches of Zanzibar after their safari, it can be a very busy time in the archipelago.
In November, the temperatures begin to rise and, after a build-up of clouds in the morning, the “short rains” descend in the afternoons. By Christmas time, you can expect a little more sunshine and for scuba divers, this is the best time to encounter whale sharks.
