Dive briefing
AI-generated
Conditions are marginal today. Raw wave heights run 0.4 to 0.9m with short-period chop between 3.8 and 4.8 seconds — that chop is the limiting factor and will make conditions rougher than the raw numbers suggest. You'll need intermediate certification and a steady hand on the line. Water temperature sits at 29.8 to 30.6°C. The site faces the trade winds on the north shore, so this exposed position amplifies what the swell brings.
Divers commonly log Stoplight Parrotfish, Atlantic Blue Tang, and Caribbean Bluehead Wrasse here, along with Schoolmaster Snapper and Queen Angelfish. Atlantic Sergeant Major and Yellowtail Damselfish are also often recorded. Depths run 8 to 25 metres across the reef.
