This article is for new scuba divers that are not familiar with blackwater diving. Blackwater diving occurs at night and in open water. It typically takes place at dive sites with minimal or no light. We call it “blackwater diving” because the water appears black due to the lack of light.
It is a type of night diving but the two terms are not always synonymous. Night diving typically refers to diving after sunset at sites nearer to shore. Dive sites like we the Blue Heron Bridge where ambient light from nearby buildings is enough to dispel some of the darkness. Blac water diving is a total difference experience.

What is a Blackwater Dive?
Blackwater diving is an adventure that usually takes divers far offshore. Exactly how far offshore you have to travel depends on where in the world you are. But the wait is well worth it, as blackwater diving offers a completely different perspective of the world beneath the waves. As you descend into the depths, you’ll be surrounded by a vast expanse of darkness, punctuated only by the faint glow of dive lights. It’s in this mysterious darkness that a hidden world comes alive.
Most blackwater dives are done in water too deep to dive to the bottom. Unlike other scuba divers, the point is not to see the bottom and the life that resides there, it is to examine the life that lives at different strata of the ocean. Some divers never descend more than 10 feet below the surface. Other divers explore the 30-60 foot strata. A few divers with the appropriate certification may explore the 60-100 foot strata. Each ocean stratum has different life in it; you can do many black water dives and still be discovering new things.
Beyond the thrill of encountering unique marine life, blackwater diving offers divers an opportunity to deepen their understanding and appreciation of the ocean’s ecosystems. Observing these creatures in their natural habitat gives us insights into their behavior, adaptations, and ecological roles. It serves as a reminder of the interconnectedness of all life beneath the waves and the importance of preserving and protecting these fragile environments.
