Ranges span today's hours. Wave height here is the raw sea state — the rating scales it for how exposed the site is. Semi-exposed — partial protection, so swell is scored at three-quarters of its open-water height.

Dive briefing

AI-generated

Conditions are marginal today. Raw wave height runs 0.7–0.9 m with short-period chop on top, which the rating flags as the limiting factor. You're looking at an intermediate site between 10 and 40 metres on a semi-exposed location, so expect some surface chop to work through to the wall. Water sits at 29.9–30.2°C. The dive suits the certification level, but you'll want to be comfortable with rougher water entry and exit.

Divers commonly log Atlantic blue tangs, stoplight parrotfish, and angelfish across the reef. Nurse sharks and Caribbean reef sharks are often recorded here, along with great barracuda. The site's known for garden eels on the sand flats and turtles working the wall, though any sighting depends on the day.
