The best season to visit Zanzibar for snorkeling and diving is July – September and January – February, when the water is clearest and marine life most abundant. Coral reefs, whale sharks, and dolphins are highlights.
Spice plantations, Stone Town, and coastal villages can be enjoyed year-round, but the short dry season (December – February) and long dry season (June – October) offer cooler, less humid conditions. This is also when cultural festivals fill Zanzibar City with music and food markets.
If you’re looking for the cheapest time to travel to Zanzibar, consider the long rains (March – May). While showers can be heavy, mornings are often clear. Resorts run attractive specials, and the atmosphere is lush and green. This is also when you’ll want to know what to do in Zanzibar when it rains, visit spice farms, museums in Stone Town, or enjoy wellness retreats and cooking classes.
With its spice-scented breezes and turquoise tides, Zanzibar enjoys a warm, tropical climate year-round. Average daytime temperatures range between 27°C and 33°C (81°F–91°F), moderated by gentle sea breezes from the Indian Ocean. The island experiences two rainy seasons, the long rains (March to May) and the short rains (November), but sunshine dominates most days, making Zanzibar Holidays perfect for swimming, snorkeling, and sunset dhow cruises almost any time of year.
January
Peak season on the island, ideal for beach relaxation, diving, and romantic escapes. Many resorts host special New Year events and candlelit dinners by the ocean.
February
Continues the dry, sunny weather, perfect for kitesurfing, sailing, and day trips to Prison Island or Jambiani’s coral lagoons.
March
Hot and humid, with early rains creating vivid green scenery. Ideal for photography and fewer crowds at Stone Town attractions.

The wettest month in Zanzibar. Resorts are quiet, the beaches deserted, and the island feels private and serene.

The rains begin to taper off, leaving behind lush vegetation and dramatic coastal skies, perfect for travelers seeking solitude and great deals.
June
The island comes alive again after the rains, perfect for beach walks, cultural tours, and spice farm visits.
