ZANZIBAR WEATHER

Your essential guide to Zanzibar: Weather, winds, and when to visit

Dreaming of a tropical escape to the spice island of Zanzibar? Your perfect beach holiday is calling. With warm temperatures year-round and distinct seasonal changes driven by the Indian Ocean's monsoon winds, planning your trip is easy with this monthly weather guide.

The best time to visit Zanzibar

For the ultimate beach holiday with reliable sunshine and minimal rain, the best times to visit are during the island’s two dry seasons:

Long Dry Season (June–October): The most popular time to visit, with sunny days, low humidity, and pleasant temperatures averaging 28–32°C. Excellent for all water activities.

Short Dry Season (mid-December–mid-March): Another fantastic period, offering hot, dry weather with plenty of sunshine. Temperatures are at their peak, often reaching 32–34°C, with crystal-clear water ideal for diving and snorkeling.

Trade winds and seasons explained

Zanzibar’s climate is governed by the two annual monsoon winds:

Kaskazi (North Wind): This warm, dry wind blows from the northeast between mid-December and mid-March. It brings hot and dry conditions, creating ideal, flat-water conditions for beginners and intermediate kitesurfers.

Kusi (South Wind): The Kusi is the stronger of the two winds, blowing from the southeast between June and October. It is most consistent in July, August, and September, and is ideal for experienced kitesurfers

What to wear in Zanzibar

Respectful and practical clothing is key for your trip to Zanzibar.

General packing advice:

Lightweight, breathable fabrics: Given the heat and humidity, pack loose-fitting clothing made from natural fibers like cotton, linen, and silk.
Sun protection: The sun is strong year-round. A wide-brimmed hat, sunglasses, and high-factor, reef-safe sunscreen are essential.
Insect repellent: Pack effective insect repellent, especially for evenings when mosquitoes are most active.

For Stone Town and local villages:

As a conservative, predominantly Muslim society, modesty is important when visiting Stone Town or local villages.

For women: Maxi dresses, long skirts, or loose-fitting trousers are recommended. Ensure your shoulders and knees are covered. A light scarf is also useful for visiting religious sites.
For men: T-shirts or polo shirts with lightweight, knee-length shorts or trousers are appropriate.

For resorts and beaches:

Resort and beach areas are more relaxed, but full nudity is illegal.

Swimwear: Bikinis and swimsuits are fine on the beach and by the pool.
Cover-ups: When walking along the beach or heading to a restaurant, a kaftan, sarong, or lightweight cover-up is recommended.

Footwear:

Sandals and flip-flops: Essential for the beach and exploring resort grounds.
Walking shoes: Comfortable closed-toe shoes or sturdy sandals are ideal for exploring Stone Town’s uneven streets and going on forest walks.
Reef shoes: Consider packing these to protect your feet from sea urchins and coral, especially during low tide.
