How Safe Is the Ocean in Zanzibar for Swimming?

With its turquoise waters and powder-white beaches, Zanzibar looks like a swimming paradise ,and for the most part, it is. But like any tropical island, knowing the conditions before diving in is key to having a safe and enjoyable experience.

At Mandari Travel, we’re often asked: “Is it safe to swim in the ocean in Zanzibar?” The short answer is: Yes, with a few smart precautions. Here’s everything you need to know before you take a dip.

1. Calm, Warm Waters – Perfect for Swimmin

Zanzibar’s ocean is typically warm, clear, and calm, especially on the west and north coasts. Beaches in areas like Nungwi, Kendwa, Pongwe, and Kiwengwa are popular for swimming, thanks to gentle waves and minimal currents.

Water Temperature: Averages 26–29°C (79–84°F) year-round
Best Time for Swimming: June to October, and December to February (dry seasons)

2. Tides Matter More Than You Think

Zanzibar experiences dramatic tidal changes, especially on the east coast (Paje, Jambiani, Matemwe). At low tide, the sea can retreat hundreds of meters, exposing coral, seaweed, and sea urchins ,not ideal for swimming.

Check tide charts daily
Pro Tip: Stay on the northwest coast (Nungwi/Kendwa) if you want full-day swimming access regardless of tides.

3. Sea Urchins & Coral: Wear Water Shoes

In shallow areas, especially during low tide, sea urchins and sharp coral can be a hazard. Wearing reef-safe water shoes is strongly recommended to avoid cuts or stings.

Also, avoid touching any marine life ,some creatures may sting if disturbed.

4. Swimming with Marine Life

Zanzibar’s waters are home to friendly marine life, including colorful fish, dolphins, and sea turtles. While sharks are present in the Indian Ocean, encounters are extremely rare, especially near the beach.

Always swim in designated areas, preferably where there are other swimmers, and follow the guidance of your tour guide or resort staff.

5. Safe Beaches for Families and Seniors

Some of the safest and most accessible beaches for gentle swimming include:

Kendwa Beach – Calm water all day, minimal tide effects
Nungwi Beach – Great for swimming and sunset views
Pongwe – Sheltered and ideal for a peaceful float

Ask Mandari Travel to recommend or book beachfront accommodations with direct, safe swimming access.
