Zanzibar's marine environment showcases diverse marine species, providing a rich snorkelling experience. Snorkelers can encounter various creatures like juvenile lionfish, shrimps, gobies, and puffers, along with notable fish species such as the Arabian angelfish and palette surgeonfish (also known as Dory). The sandy seafloor is home to red-knobbed starfish, Pentaceraster, and several sea urchin species. Seagrass beds often host tiger snake eels. Additionally, Zanzibar's waters harbour two clownfish species, the two-bar anemonefish and the skunk clownfish, which coexist alongside porcelain crabs and three-spot dascyllus, forming unique underwater communities.

Best Time for Snorkelling in Zanzibar:

The ideal time for snorkelling in Zanzibar aligns with the dry season, which spans from June to October. This period offers exceptional water clarity and optimal visibility. The winter months (July to September) bring slightly cooler temperatures, ranging from 72 to 75°F (22-24°C). Water temperatures in Zanzibar are consistently pleasant, averaging around 86°F (30°C) in February and March.

However, Zanzibar's underwater world remains accessible year-round, even during the rainy season, as showers are often followed by sunny breaks. Zanzibar's tropical climate ensures hot and humid weather throughout the year.
The island experiences two distinct rainy periods that can be avoided:
  • Long rains occur from late March to May.
  • Short or light rains are observed in November and December.

Renting Snorkelling Gear & Equipments

In Zanzibar, most snorkelling and diving operators typically offer snorkelling equipment as part of their packages, but it's a good idea to confirm this with them beforehand. Alternatively, there are rental options available on the island for those who prefer flexibility. Snorkel rental, which includes a mask, fins, and snorkel, usually costs between $10 and $12 per day. It's recommended to bring your swimsuit, a towel, and sunscreen for a comfortable experience.
If you wish to capture your underwater adventures, consider bringing a waterproof/underwater camera; some operators also provide camera rentals at approximately $30 per day.
