Zanzibar, the exotic island off the coast of Tanzania, is famous for its white-sand beaches, turquoise waters, spice plantations, and historic Stone Town. If you’re planning your dream island escape, knowing the best time to visit Zanzibar can help you make the most of your holiday—whether you’re after sunshine, festivals, or water sports.
In this guide, we’ll break down the seasons, festivals, and travel tips to help you plan the perfect trip.
Understanding Zanzibar’s Climate
Zanzibar has a tropical climate, which means it’s warm year-round but also subject to rainy seasons. The average temperature hovers between 25°C to 32°C (77°F to 90°F). The island experiences two main rainy periods and two dry periods:
-
Long Rains: March to May
-
Short Rains: November
-
Dry Seasons: June to October and December to February
Each season offers something unique depending on what you’re looking for.
Best Time for Beach Holidays and Sunbathing
If your priority is lounging on the beach or swimming in crystal-clear waters, the dry seasons are ideal:
-
June to October: Pleasant temperatures, lower humidity, and clear skies.
-
December to February: Warmer and slightly more humid, but still excellent for beach activities.
During these months, the ocean is calm, and the water visibility is perfect for snorkeling, diving, and swimming. Popular beaches like Nungwi, Kendwa, and Paje are buzzing with activity, beach bars, and sunset parties.
Best Time for Diving and Snorkeling
Zanzibar is one of Africa’s top diving and snorkeling destinations. The best underwater visibility and marine life sightings are during:
-
March and April (before heavy rains): Ideal for diving, especially around Mnemba Atoll.
-
July to September: Cooler water but still excellent visibility and active sea life.
-
February: Often a top choice due to optimal water clarity and weather conditions.
If you’re an underwater enthusiast, timing your trip for these windows ensures the best coral reefs and vibrant marine encounters.
Best Time for Cultural Exploration and Festivals
Zanzibar is more than just beaches—it’s rich in culture, history, and tradition. Some of the best times to experience this side of the island include:
-
July: The Zanzibar International Film Festival (ZIFF) is one of East Africa’s largest cultural events. Expect live music, art, and global cinema.
-
October: The Sauti za Busara Festival sometimes falls around this time—an incredible celebration of African music in Stone Town.
-
During Ramadan (varies yearly): While some businesses slow down, it’s a unique time to witness local customs and enjoy traditional Zanzibari Iftar meals after sunset.
Stone Town, a UNESCO World Heritage Site, is always a must-see, but visiting during cultural festivals adds a whole new layer of experience.
Traveling During the Rainy Season
While most tourists avoid the wet seasons, you can still visit Zanzibar during the green season with some planning.
-
March to May: This is the long rainy season, with heavy showers that may limit beach and boat activities. However, it’s a peaceful time with lower prices.
-
November: The short rains are brief and often occur in the afternoon. Mornings can still be sunny and warm, making it a decent shoulder season.
If you don’t mind occasional rain and want to avoid crowds, traveling during the rainy season can offer significant discounts on hotels and tours.
Month-by-Month Breakdown
Here’s a quick reference guide for travelers looking to pick the best time to visit Zanzibar:
| Month | Weather | Highlights |
|---|---|---|
| Jan–Feb | Hot & dry | Great for beaches, diving, and kite surfing |
| Mar–May | Long rains | Fewer tourists, best prices |
| Jun–Oct | Cool & dry | Ideal for sunbathing, sightseeing, & safaris |
| Nov | Short rains | Less crowded, light showers |

Best Time for Budget Travelers
For those watching their wallet, March to May and November are budget-friendly periods. Hotel rates are lower, tours offer deals, and the island is much less crowded. However, be prepared for unpredictable rain showers.
When to Avoid Visiting Zanzibar
While Zanzibar can be visited year-round, the peak of the long rains (April and May) is generally considered the least favorable time. Roads can become muddy, some hotels close for renovations, and the sea can be rough. If beach relaxation and water activities are your main goals, it’s best to avoid this window.
Conclusion
The best time to visit Zanzibar really depends on your travel style. For sunny days on the beach and crystal-clear water, go between June and October or December to February. For cultural festivals and a deeper connection with Zanzibari heritage, July and festival months are ideal. And for those who prefer quiet escapes and great deals, the green seasons of March–May and November are worth considering.
Whether you’re snorkeling with dolphins, dancing at music festivals, or simply watching the sunset with fresh seafood on the sand, Zanzibar offers something magical in every season.
