If you are looking for one of the best scuba diving locations in the world, Zanzibar is always at the top of the list. Zanzibar is an archipelago located in the Indian Ocean. This semi-autonomous territory is officially a part of Tanzania. The waters surrounding this African archipelago are some of the warmest, clearest, and in terms of marine life, the most bountiful in the world. Let’s discuss what you can expect when scuba diving in Zanzibar.

Zanzibar Scuba Diving Overview and Basic Facts

In Zanzibar, there are well over 30 different dive sites to choose from. You can find all sorts of diving adventures and types, including wall and reef diving, shark cage diving, and shipwrecks.

The Levan Bank sees very strong ocean currents and is a haven for large game fish such as tuna, trevally, and kingfish.

The Best Time of Year to Dive Around Zanzibar

The best part about diving around Zanzibar is that the Indian Ocean in this area sees very consistent temperatures year-round, often being around 80° Fahrenheit (nearly 27° Celsius). You can expect the water to be up to 29° Celsius or over 84° Fahrenheit between November and May.

You can expect the water to be a balmy 25° Celsius or about 77° Fahrenheit in the rainy season between June and October.

As you can see, no matter the time of year, the waters around Zanzibar are always warm. However, most scuba divers would agree that the best time to dive Zanzibar waters is mid-March to mid-April.

On that same note, while the oceans around Zanzibar can be a bit choppy at times, between March and May, strong winds subside and allow for very calm water. Moreover, you can expect the water visibility to be up to 60 meters or close to 200 feet during calmer times, which is fantastic.

Finally, depending on the dive site, you can expect the currents to be moderate to strong.

Keep in mind that although March, April, and May tend to be the best months in terms of scuba diving conditions around Zanzibar, if you want to see dolphins, whale sharks, and turtles, the best time is from September to December.
