What is blackwater diving?
Blackwater diving is a type of scuba diving that takes place at night in the open ocean at depths ranging from 20 to 40 meters (60 to 120 feet). It is sometimes called an offshore blackwater dive, or open ocean blackwater dive, blackwater night dive, or blackwater drift dive, because of the nature the dive.
Using a small boat or buoy, scuba divers tether themselves or float with the current while marine life from the depths of the ocean ascends towards the surface. During a blackwater dive, various deep-sea species that are rarely seen during the day emerge from the dark abyss. In these deepest parts of the ocean, thousands of colorful pelagic and planktonic creatures float to the surface every night to feed and breed.
Divers have to use their dive lights and other gear to find their way and figure out where they are in the open ocean, while searching for pelagic creatures. This makes blackwater diving harder than a regular night dive. For blackwater diving to be safe, scuba divers must be able to control their buoyancy well and be comfortable diving at night.
Why do divers love doing blackwater dives?
Experienced divers and photographers love blackwater dives because of the bizarre and rare creatures like jellyfish, squids, salps, and even critters in their larvae stages. There is always an element of surprise when you’re diving in the dark and waiting for creatures to emerge out of nowhere.
In my experience, it was like stepping into a whole new galaxy. In the darkness, you could see all these tiny creatures floating and glowing, like tiny stars and planets in a pitch black outer space. It was fascinating, thrilling, and peaceful all at the same time.
In addition to the cool animals you might see, blackwater diving is a fun activity that lets you test your limits. You need to overcome any fears you have, practice drift diving, and have good buoyancy control while diving in the dark.
For some divers, the biggest appeal is simply learning more about the secrets of our ocean. The fact that just 5% of the ocean has been explored makes the prospect of blackwater diving even more exciting.
What creatures will you see during a blackwater dive?
One of the highlights of these dives is the opportunity to witness the abundance of plankton present in the water. Plankton are tiny organisms that are carried by currents and tides. During the night, a phenomenon known as diel vertical migration occurs. This is when plankton and bigger animals like squid and krill rise from the depths of the ocean.
Blackwater diving allows you to witness this incredible spectacle, as well as encounter a variety of other alien-like creatures such as fish larvae, juvenile fish, squid, salps, jellyfish, and octopus. It’s not uncommon to even spot larger pelagic species like dolphins or sharks passing by. The opportunity to witness these diverse and fascinating creatures hunting and being hunted is one of the reasons why blackwater diving is so popular among enthusiasts.
Additionally, blackwater diving also offers the chance to observe macrolife in its various stages of development. You will encounter juveniles of all sorts of animals, such as crabs, shrimp, seahorses, octopus, cuttlefish, and many other species of fish that have yet to settle on the reef.
Most reef inhabitants start off in the water column, often camouflaged against predators by being transparent and possessing other bizarre mutations that make them harder to prey on. This makes for a truly mesmerizing and otherworldly experience, unlike any other, and it offers fantastic opportunities for photography of these unique and elusive creatures.
What happens during a blackwater dive?
There are different ways to do a blackwater dive. Some dive shops or liveaboard drop a line and require the divers to be tethered or clipped to these lines. While others allow you to swim freely within a certain area below a buoy or a boat.
During my blackwater dive in Romblon, I experienced the latter. Here’s what happened during my blackwater dive:
- My buddy and I attended a dive briefing explaining what will happen during the dive. Any questions, clarifications, and concerns were brought up and these were addressed by our guide.
- After checking our gear, we boarded the boat to go to the dive site.
- Once we found the spot, the dive guide deploys the special buoy setup used for blackwater diving. This buoy had a blinking light so boats can see it in the dark. The buoy also had a rope line with dive lights every 5 meters. This line with lights not only attracts the critters but also served as our depth guide and reference point.
- We backrolled into the water one by one, and once everyone was ready, we descended for our blackwater dive.
- After 60 minutes of drift diving our guide signaled us that it was time to ascend. We did our safety stop and exited the water several hundred meters away from where we had started.
It is important for divers to follow all dive safety guidelines and to stay with their dive group during the dive. Follow the procedures set by the dive shop you will be diving with.
Is it scary to do a blackwater dive?
Blackwater diving may be fun and gratifying, but it’s not for everyone. Some divers fear night diving in deep water with little vision and strong currents. The unknown, deep water, currents, and marine life may make a blackwater dive “frightening.”
Divers should be honest about their skills and experience and only conduct a blackwater night dive if they feel competent. It’s better to dive with expertise and comfort than to push yourself and feel overwhelmed. Uncovering the unknown and the potential to see exotic marine creatures make the dive particularly memorable, but it’s not for everyone.
As a seasoned diver, I find blackwater diving to be an exciting experience. I honestly felt scared at first, but diving with other experienced dive guides and a trustworthy dive shop put my nerves at ease.

Is blackwater diving dangerous?
Blackwater diving, like any other sort of diving, has its own hazards and risks. It’s important to know about these dangers and take steps to make sure a dive is safe.
If you are going scuba diving in blackwater, you will be diving in an open ocean where you can’t see the bottom. For many divers, this can be more difficult as there is nothing solid under or beside you for a reference point.
You can also expect stronger currents that can be confusing as well as riskier for any diver. With your limited field of vision at night, you might also have difficulty navigating. It is very common to feel disoriented while doing a blackwater night dive.
Although the marine life in black water may be fascinating, many of them can also be dangerous sea creatures that you should avoid. Jellyfishes can appear out of nowhere and can sting you.
To reduce these dangers, make sure you have the necessary skills and knowledge to do a blackwater dive. Always respect the marine environment and approach anything you see with caution. Only dive with a trusted dive center, and always follow dive safety recommendations.
Where can I experience blackwater diving?
Blackwater diving usually takes place in tropical areas with strong currents and a lot of marine life in the water column. Hawaii, Florida, Philippines, Indonesia, Palau, Cozumel, and Roatan are some of the popular places for blackwater diving.

At these places, dive centers and liveaboard dive boats often offer trips for blackwater diving. When planning a dive, safety should always be your top priority. Doing your research will help you have a safe and fun time.
What are the requirements for blackwater diving?
Blackwater night diving can be a challenging and interesting experience, but divers need to have the right skills and experience to do it safely.
Most dive shops and liveaboard dive boats that offer blackwater diving will require divers to have at least an advanced open water diving certification. This is because blackwater diving typically involves diving to deeper depths and in less predictable conditions than other types of diving.
It is important for divers to not just have some experience with night diving, but also be comfortable and confident diving at night.
Divers need to have good buoyancy control so they can stay in the same place in the water column.
Some dive shops will ask you to do a checkout dive first so they can assess if you have the skills to do a blackwater dive.
It is always a good idea for divers to have dive insurance, especially when participating in more advanced types of diving such as black water diving. This can provide financial protection in case of an accident or injury.
It is always best to check with the dive shop or liveaboard dive boat regarding their specific requirements for blackwater diving as it varies for each location.

What special gear do you need for blackwater diving?
In addition to the standard scuba diving gear, there are a few additional pieces of equipment that may be helpful for blackwater diving:
- Dive lights: Blackwater diving often takes place at night, so it is essential for divers to have a reliable dive light in order to navigate and orient themselves in the water. It is recommended to carry a main light and a backup light. Read my post on 10 Best Dive Lights for Recreational Scuba Divers if you need to get a new one prior to your night dive.
- Scuba tank marker lights: To help mark or locate divers in the water, and make it easier for the dive boat or raft to spot you.
- Surface marker buoy: A surface marker buoy (SMB) is a brightly colored inflatable tube that helps to mark the diver’s position and make them more visible to the dive boat or raft. This would be very useful especially if you get lost at sea.
- Dive computer: Make sure that you have a dive computer that can easily help you track your dive time and depth. Dive computers that constantly have the backlight on work best so you can easily check your dive profile.
- Full-body wetsuit: It is a good idea to wear a full-body wetsuit to protect yourself from stinging animals. Water temperature also drops at night so the extra length can help keep your extremities warm.
- Dive hood: These can also keep your head warm while diving at night. Wearing hoodies can keep small planktons and wriggly critters from going into your hair or touching your neck or face.
- Underwater camera: Not required but highly recommended! The creatures found during blackwater diving are often not found in a typical night dive so take advantage and photograph the cool critters you see. Check out my post on Best Scuba Diving Cameras For Beginner Underwater Photographers for some ideas.
If you don’t have these, you can check your dive shop if it is included in the package or if you can rent them.
Before going on a blackwater dive, it’s important for divers to make sure that all of their gear is in good shape and that they know how to use it. Blackwater diving can be a challenging and tough experience, and having the right gear can make all the difference in having a safe and enjoyable dive.
