Best month
July

↑The driest and clearest month of the cool season: 28mm of rain, 8.2 sunshine hours, and the best underwater visibility of the year — Mnemba Atoll diving and Nungwi snorkelling are at their finest
↑Whale shark season peaks in July and August — encounters are more frequent than June and the south coast tours are fully operational with experienced guides and well-maintained equipment
↑Festival of the Dhow Countries (mid-July) runs alongside the ZIFF finale — a celebration of Indian Ocean culture across music, film, and crafts that makes Stone Town extraordinary to visit for the combined two-week festival period
