Diving in Zanzibar: The Only Complete Guide You’ll Ever Need
Anyone who loves diving probably has Zanzibar on their bucket list. I know I did, and four decades ago, I set up Swahili Divers on Pemba Island and never looked back.
The coral reefs here are teeming with life, the water’s warm and clear and there's something for every dive level.
Let's get to the good stuff – is diving in Zanzibar worth it? Definitely!
With this guide, you'll have the trip of a lifetime, filled with incredible underwater encounters, and maybe even a chance to tick some dream dives off your list.
Here’s everything you need to know about diving in Zanzibar.
I'll share all the secrets I've learned over four decades of diving here, from the best spots to see specific marine life to essential tips for making the most of your dives.
Why Dive in Zanzibar?
According to the OCGS tourism stats, Zanzibar recorded 73,468 international visitors in January 2024. Thousands of these tourists come here to Scuba dive and experience extraordinary marine life.
Here’s why you too should consider diving in Zanzibar.
1. The Critters:
When you go diving in Zanzibar, you'll see everything, from tiny critters like nudibranchs to absolute giants like whale sharks (at the right time of year).
You can expect to see mantas, dolphins, turtles, and more colorful reef fish than you can count. There’s over 500 marine species waiting for you over here.
Sharks get their own section later – they're a big part of why Zanzibar's so popular.
2. Sites for Everyone:
If you're just starting your dive journey or you've logged thousands of dives, there are spots to suit you. Gentle reefs, walls, drift dives, and a few wrecks too, if that's your thing.
For beginner divers, the shallow reefs off Nungwi or Kiwale Island are perfect for a relaxed dive. More experienced divers will enjoy the drift dives along the walls at Kendwa Reef or explore the underwater caverns of Pemba Island's Valerie Caves.
3. Comfortable Conditions:
The water's warm here year-round. Sometimes a 3mm wetsuit will do, and occasionally the hardcore divers even go without! Visibility is usually good, especially when the weather's settled.
The best months for diving in Zanzibar are June to October, the dry season.
Expect sunshine, calm seas, and the best visibility. You can still dive during the shoulder seasons (November-December and March-May) but there's a chance of short rain showers, and occasionally rough seas can affect boat trips.
4. More Fun Things to Do in Zanzibar.
Don't get me wrong, you can easily fill your days underwater, but Zanzibar has a lot of fun to offer, beyond diving.
There are incredible beaches, sun dhow cruises, the historic Stone Town is worth exploring, and spice farm tours that worth every penny.
Marine Life on Zanzibar
Here are just a few of the marine animals you can expect to see on a dive in Zanzibar:
Coral reefs: Zanzibar is home to some of the most diverse coral reefs in the world. These reefs are home to a variety of fish species, including clownfish, angelfish, butterflyfish, and parrotfish.
Sharks: There are a number of sharks that can be seen in Zanzibar, including blacktip reef sharks, whitetip reef sharks, and eagle rays.
Dolphins: Zanzibar is home to a number of dolphins, including spinner dolphins, bottlenose dolphins, and humpback whales.
Turtles: You’ll find a good number of turtles that can be seen in Zanzibar, including hawksbill turtles, green turtles, and loggerhead turtles.
Rays: A variety of rays can be seen in Zanzibar, including stingrays, manta rays, and eagle rays.
Sharks in Zanzibar
Sharks deserve their own section, as they're a major draw for divers.
Reef Sharks: You'll spot these on lots of dives, especially around Mnemba. They're shy and completely safe, though I still get a thrill whenever I see one out on the reef.
Whale Sharks: Mnemba Atoll is the best spot for these gentle giants. Remember, be a respectful observer and keep your distance. It's honestly incredible to be in the water alongside such a massive, yet graceful creature.
Hammerhead Sharks: These are much rarer, but there's always a chance, especially if you dive regularly around Zanzibar. Chat to local dive centers about the best spots to maximize your chances.
In addition to these amazing animals, you can also expect to see a variety of colorful fish, plants, and invertebrates on a dive in Zanzibar. The marine diversity in Zanzibar is truly stunning, and it is an experience that you will never forget.
When is the Best Time to Dive in Zanzibar
Diving's possible year-round, but the seasons do make a difference. Here are the best months to visit Zanzibar for Scuba diving:
June to October (Dry Season):
Hands down the best conditions. This is peak season for a reason. You'll get calm seas, fantastic visibility (sometimes 30 meters or more!), and lots of sunshine above the water.
Of course, this also means busier beaches and slightly higher prices.
I remember one October when the whale shark sightings were off the charts! We saw them on almost every dive around Mnemba for a whole week. It was incredible seeing these massive but gentle fish gliding right before our eyes.
November to December (Short Rains):
The occasional shower rolls through, but they rarely last long enough to ruin a dive day, and you'll be rewarded with smaller crowds on the reefs and at the resort. It's honestly still a great time to visit.
There was a November a few years back, in 2020, when we had a surprise week of perfectly calm seas and super-clear visibility during the short rainy season. My team and I were amazed at how Zanzibar can always throw a curveball!
March-May ( Heavy Rains ):
Visibility often decreases, and rough weather can prevent boats from going out on some days. It's still possible to dive, and many dive centers remain open, but it might mean fewer sites are regularly visited.
For experienced divers, a good local dive center will still be able to find some sheltered spots, away from the worst of the weather.
Whale Shark Season (October - March):
If seeing these amazing creatures is your dream, plan your trip during these months.
They're most often spotted around Mnemba Atoll, and while sightings are never guaranteed, if you're diving regularly during this period, you have a great chance!
A Note on Seasonality
Zanzibar's weather patterns aren't always completely predictable. Occasionally, even in the rainy season, you could hit a stretch of amazing weather, and the reverse can be true sometimes in the dry season.
Tips for Timing Your Trip Perfectly
Flexibility is Key: If possible, allowing a bit of flexibility in your travel dates gives you more options to chase the best conditions. Keep an eye on the weather forecast in the weeks before your trip.
Talk to Local Dive Operators: They're your best source of up-to-date info on current water conditions and how the season is shaping up.
Aim for "Shoulder Seasons": If crowds aren't your thing, consider coming right before or after the peak dry season. You'll still get fantastic diving with fewer people around.

Finding Dive Centers in Zanzibar:
You've got loads to choose from across the island, and many have great reputations.
Always go for a PADI-certified center – that shows they meet international safety standards (check on the PADI website for reassurance).
Of course, Swahili Divers on Pemba Island is a fantastic choice (wink, wink).
Resorts and Accommodation in Zanzibar
Zanzibar has some of the spectacular resorts in East Africa, the likes of the Manta Resort and the Aiyana resort on the luxury end.
But, most divers prefer more down-to-earth accommodation options in Zanzibar, closer to nature and to the beaches.
The cozy, clean and comfortable beach-side bungalows on the Swahili Gecko nature Lodge are just perfect for divers.
The beach view and Zanzibari food is what sets the resort aside. It is also very affordable and will fit any diver’s budget.
Liveaboards:
Liveaboards are the way to go if you're serious about diving and wanna reach further-off sites.
They usually run multi-day trips and it's shared accommodation – this option is best suited for divers with a bit more experience.
Weather in Zanzibar
Zanzibar boasts a tropical climate, with water temperatures ranging from 26°C to 29°C (79°F to 84°F). Visibility can stretch up to 30 meters, offering crystal-clear views of the underwater world.
How to Get to Zanzibar
You'll probably fly into the international airport on Unguja (Zanzibar City). To reach Pemba, it's either a quick flight or a ferry ride across, depending on where exactly you want to stay.
Flights: The main way to get to Zanzibar is flying into the international airport on Unguja (Zanzibar City). From there, you've got a few options:
Connecting flight to Pemba: This is the quickest way if you're staying on Pemba Island. Pemba has a smaller airport, with several short flights a day from Unguja.
Ferry to Pemba: If time isn't a major factor, the ferry across is cheaper than flying. It takes about 2-3 hours, and it's a scenic journey with views of both islands.
Staying on Unguja: If Unguja is your base, you'll find plenty of ground transportation from the airport to your chosen resort or guesthouse. Local taxis are available, or pre-arrange a shuttle with your accommodation.

Where is Zanzibar Located?
Some people wonder if Zanzibar is a country. It is not. The archipelago is part of the Republic of Tanzania, forming the country’s East Coast on the Indian ocean.
It's an archipelago off the coast of mainland Tanzania in East Africa. The two main islands of Zanzibar are Unguja (which most people just call Zanzibar) and Pemba island (The green island).
Here’s a map of Zanzibar for better planning.
Best Dive Sites in Zanzibar
I've spent decades exploring these sites, so I've got plenty of stories and details to share! There are loads of spots dotted around Zanzibar, but here are a few you shouldn't miss:
1. Mnemba Atoll:
This is THE classic Zanzibar dive, and with good reason. The reefs are pristine, there are always tons of turtles, playful dolphins often make an appearance, and there's always a good chance of spotting reef sharks cruising through the blue.
One of my most memorable Mnemba dives was when a pod of dolphins decided to check us out. They circled around the group, coming so close we could almost reach out and touch them – absolutely incredible!
2. Leven Bank:
This one is for serious divers. It's an open ocean site, so currents can be powerful. But that's exactly what attracts all the big fish.
Massive schools swirl around you, and there's always the possibility of larger sharks like grey reefs or even a tiger shark if you're really lucky. Leven Bank is adrenaline-pumping diving at its best.
3. Nungwi:
Right up north on the main island, this area offers a great mix. Beginners will love the shallow reefs teeming with colorful fish. There are coral bommies covered in life, and it's a turtle hotspot too.
More experienced divers have deeper walls and drift dives to choose from, with plenty of big critter action.
4. Kiwale Island:
Just off the east coast, this small island boasts stunning coral gardens bursting with life. It's a shallow dive, perfect for beginners who want to take their time and soak up all the colors and textures of the reef.
It's also excellent for macro photographers. I always recommend keeping a close eye on the coral crevices for octopus or camouflaged scorpionfish.
5. Pongwe Reef:
This fringing reef is a favorite for all levels. Relaxed shallow bommies with loads to see, and the chance of spotting turtles grazing on seagrass. For experienced divers, the wall is where the action's at.
Bigger fish cruise along the deeper sections, and the occasional eagle ray sighting isn't uncommon.
6. Kendwa Reef:
Another fringing reef, but this time on the west coast. Strong currents can sweep past here, making it an exhilarating drift dive. The reward is a spectacular wall thriving with fish life.
Be on the look out for eagle rays and barracuda patrolling the deeper areas.
7. Pemba Island: Swahili Divers' Home Base
Pemba Island offers fantastic diving too, with sites like the Manta Reef, famous for predictable manta ray encounters, and the stunning Valerie Caves, a network of underwater caverns.
Visibility here can be exceptional, and the marine life is just as diverse as on Zanzibar.
Here are a few highlight dive sites on Pemba island:
Manta Point:
This is the place manta ray enthusiasts dream of. During the right season, the chances of seeing these graceful giants are incredibly high, and they often come in close for a look!
Valerie Caves:
A network of underwater caverns and tunnels. With light filtering through and interesting rock formations, it's a thrilling and unique dive site. Just watch out for the resident lionfish hiding in the darker nooks!
Misali Island:
Misali is known for its pristine reefs and diverse marine life. Expect to see turtles, dolphins, schools of tropical fish, and maybe even a glimpse of a shark cruising through the blue.
You also get the added bonus of a beautiful island to relax on during your surface intervals!
