The best time to visit Zanzibar is during the archipelago’s dry season, from July to September, which is a very popular time to travel. However, it’s worthwhile travelling at most times of year, with balmy temperatures between 28°C and 34°C and sunshine the norm. During the short rains in November and December, downpours are followed by blue skies. It’s only very wet during the peak of the long rains in April and May.
Make sure to comply with this requirement to avoid any travel disruptions at entry.
