Night Diving Essentials
What Is Night Diving?
Night diving is scuba diving done during the hours of darkness, and night dives usually begin just as the sun sets.
Why Go Night Diving?
The ocean is a completely different place at night and worth experiencing during a night dive. It is exciting and thrilling to drop into the ocean at night, and divers can enjoy seeing familiar dive sites completely differently. Dive torches only light up one part of a dive site at a time, making divers pay attention to that area. Different marine species are active at night, and it is possible to watch some marine life, such as that of sharks and lionfish, as they hunt.
Where To Go Night Diving
There are a variety of top scuba diving destinations around the world for the best night dives, each offering their own dive highlights:
Best Manta Night Dive
One of the best night dives is at Kona, on the Big Island of Hawaii. Scuba diving in Hawaii offers wrecks, caves, pristine reefs, and the chance to night dive with numerous feeding manta rays. It continues to be one of the best places in the world to spot these mysterious mantas. The mantas are drawn to the area at night thanks to coastal resort lights attracting plankton, which the mantas feed on.
Best Shark Night Dives
Diving with sharks at night is truly exhilarating, as sharks are often more active than during the day and focused on hunting. There are some great shark night dives to experience, including the Great Barrier Reef in Australia, the Maldives, and Costa Rica.
Great Barrier Reef, Australia
The OceanQuest liveaboard offers year-round dive trips to the remote Outer Great Barrier Reef in Australia, taking divers to the best dive sites in the area. This liveaboard also offers nightly Shark in The Dark dives, giving divers the chance to jump in and enjoy the reef sharks at night.
The Maldives
The Maldives may be known for encountering whale sharks and manta rays, but there is another type of shark dive experience at Felidhoo Atoll. Divers visiting Felidhoo can enjoy night diving with numerous nurse sharks and stingrays at Alimatha Jetty. The luxurious Scubaspa Yin, the Scubaspa Yang, and the Duke of York offer this relaxed shark night dive.
Costa Rica
Cocos Island is a shark lover’s paradise. It is well-known for diving with large schools of hammerhead sharks and visiting whale sharks. Manuelita Coral Garden is one of the first dive spots visited on Cocos Island trips and is full of fish life, turtles, sharks, and rays. A night dive there is not to be missed, and it gives divers the chance to watch huge schools of hunting whitetip sharks. The Cocos Island Aggressor offers action-packed dives daily and night diving with sharks.
Best Fluorescent Night Dive
Divers looking for a fun and different night dive should go to Fluoro Night Diving at the Great Barrier Reef, Australia. This unique night dive, offered by OceanQuest, uses specialist torches and mask filters to bring to life amazing fluorescent underwater landscapes.
Best Bioluminescent Night Dives
Seeing bioluminescence underwater is a real night dive highlight, especially watching your fins kick up a flurry of bright lights in the dark water. Many small organisms are bioluminescent, putting on a spectacular show for divers and filling the water with tiny fluorescent lights at various destinations.
The Maldives
The Maldives is ideal for experiencing bioluminescence while diving and also at the shores of white-sand beaches. A variety of Maldives liveaboards visit this stunning dive destination, with something suitable for all budgets and interests.
Myanmar
Great Swinton Island in Myanmar is another good destination for glowing bioluminescence and fantastic coral reef diving. This relatively new dive destination remains largely undiscovered and is visited by a handful of Myanmar liveaboards.
Best Reef Night Dives
Diving into reef structures at night is a very different experience from reef diving during the day, as marine life comes out to hunt, and dive torches highlight the colors of the reef.
Myanmar
Shark Cave in Myanmar is an excellent spot for a reef night dive. It is surrounded by rocky outcrops and a vertical wall. Divers can enjoy seeing decorated sponge crabs, Durban dancing shrimp, mantis shrimp, moray eels, and feeding pairs of cuttlefish.
The Red Sea
The Straits of Tiran and Elphinstone in Egypt have interesting reef night dives. Unlike other areas of Egypt, night diving is permitted at both destinations. These night dives offer the chance to hang in front of dramatic walls and reefs, watch hunting lionfish, and enjoy the reefs as they come alive with activity.

Best Wreck Night Dives
The idea of diving a wreck at night may sound intimidating, but some wrecks have plenty of space and good accessibility, making them ideal for exciting night dives.
The Cayman Islands
The Ex-USS Kittiwake, a former US submarine rescue ship, is one of the most sought-after wreck dives in the Cayman Islands. Lying in shallow and clear water, she is ideal for wreck night diving. With spacious corridors and clear water, she is a relatively easy wreck to dive. The Cayman Aggressor IV visits this wreck and offers night diving at the Balboa and Ore Verde wrecks.
The Red Sea
Scuba diving at the Thistlegorm in Egypt is not to be missed. It is one of the world's most famous wreck dive sites, making it even more impressive at night. Divers can see shrimps, crabs, and lionfish hunting in the light of dive torches. It is truly an awe-inspiring wreck night dive. Emperor Fleet vessels in Egypt visit the Thistlegorm, as do many other Thistlegorm liveaboard diving vessels.
Best Remote Night Dives
There is nowhere quite like French Polynesia and Papua New Guinea for truly remote and pristine diving. These remote destinations offer the chance to do lagoon night dives and macro night dives, with barely any other divers around. Diving at these destinations is one of the best adventures a diver can have.

Best Coral Spawning Night Dive
Witnessing the mass spawning of corals is a unique experience that few people get to see in their lifetime. Although it can be difficult to predict, coral spawning does occur at the Great Barrier Reef, Australia, between November and December each year. Flynn Reef off Cairns has many hard and soft coral species and is known for annual coral spawning.
Divers can witness this incredible event during night dives with the Pro Dive Cairns Fleet.

What Marine Life Can Be Seen When Night Diving?
A variety of marine life can be seen when night diving, from manta rays and hunting sharks through to tiny critters and lionfish. See the sections above for more details about each destination’s night dive highlights.
Who Can Try Night Diving?
Any Open Water Diver or equivalent certification diver can try night diving. For those interested in learning more, there is a PADI Night Diver Specialty.
What Gear Do Night Divers Need?
Divers will need a dive torch with a strong beam and a long battery life. Diving with a spare torch and a marker attached to your BCD or tank is advisable for easy recognition in the dark.
What Diving Skills Do Night Divers Need?
The most important skill during a night dive is the ability to stay calm. Diving in the dark can make divers nervous at first, so it is important to relax and enjoy the experience.
Divers should stay close to the group, stay shallow, and ensure they agree upon their dive signals before starting a night dive. Using a dive torch for dive signals during a night dive is common, instead of the traditional hand signals. Divers should use familiar equipment they have tried during the day and set up their equipment during the day or under adequate lighting.
What Are The Main Hazards Of Night Diving?
The main hazards are becoming disoriented because dive sites look different at night or panicking. This can be resolved easily by staying close to the group, diving into the site in the daytime first, and remaining calm.
