Dive briefing

AI-generated

Conditions are excellent today with a calm morning — 0.2m effective waves. The wall descent runs from 15 to 40 metres and suits intermediate certification. Expect a fast drift along the sponge-covered drop-off, with tunnels and overhangs to explore as you move along the site. Sea temperature is 29.9–30.5°C.

Divers commonly log Atlantic Sergeant Major, Atlantic Blue Tang, and French Angelfish throughout the dive. Green Sea Turtle sightings are often recorded here, along with Caribbean Bluehead Wrasse, Stoplight Parrotfish, French Grunt, and Yellow Stingray. These are citizen-science sightings, so encounters are never guaranteed, but the site has strong documentation of reef life across the wall.
