Ranges span today's hours. Wave height here is the raw sea state — the rating scales it for how exposed the site is. Sheltered — reef or lagoon protection, so swell is scored at half its open-water height.

Dive briefing

AI-generated

Conditions are marginal today. Waves are running 0.8–1.0m with a short period of 5.6–6.3 seconds, which will create chop and make the drift less comfortable than usual. The site's sheltered exposure helps, but you should be prepared for a rougher ride than the wall typically offers. Water temperature sits at 29.2–29.9°C.

This is still an intermediate dive on a sponge-covered wall with tunnels and overhangs. Divers commonly log Atlantic Sergeant Major, Atlantic Blue Tang, French Angelfish, and Green Sea Turtles here, alongside parrotfish, wrasse, and Caribbean Land Hermit Crabs. Marginal conditions won't change what you might see, but the short-period swell will be the limiting factor in how you move along the wall.
