Zanzibar Weather Overview
Zanzibar has a tropical climate shaped by two monsoon seasons. The long rains (Masika) fall from late March through May, bringing heavy daily downpours that can disrupt travel. The short rains (Vuli) arrive in November, delivering brief afternoon showers that rarely affect plans. The dry season from June to October is the most comfortable period, with lower humidity, steady trade winds, and temperatures between 23-29 °C. December to February is hot and mostly dry, perfect for sun-seekers who enjoy peak tropical warmth. Sea surface temperatures stay between 25-29 °C year-round, making Zanzibar a viable beach destination in every month outside the April-May rains.

June to October is prime diving and snorkelling season, with visibility exceeding 30 metres around Mnemba Atoll and Chumbe Island. Kitesurfing peaks from June to September on the southeast coast at Paje. Cultural activities such as Stone Town walking tours, spice plantation visits, and cooking classes run year-round. December to February is ideal for dhow sunset cruises and deep-sea fishing. Humpback whale sightings are possible off the south coast between July and September. The Zanzibar International Film Festival (ZIFF) typically takes place in July, adding a cultural highlight to the peak season.
