Zanzibar Weather Guide
Plan your perfect trip with our comprehensive guide to Zanzibar's tropical climate, seasons, and best times to visit.
Tropical Island Paradise
Zanzibar enjoys a warm tropical climate year-round, with temperatures typically ranging from 25°C to 35°C (77°F to 95°F). Located just 6 degrees south of the equator, the archipelago experiences consistent warmth throughout the year.
The climate is influenced by two monsoon seasons: the Kaskazi (northeast monsoon) from December to February bringing warm, humid conditions, and the Kusi (southeast monsoon) from June to October bringing cooler, drier weather.
With over 2,000 hours of sunshine annually and sea temperatures between 26-29°C, Zanzibar truly lives up to its reputation as a beach lover's paradise.
