Dive briefing

AI-generated

Conditions are marginal today, with 1.0m effective waves in the morning window limiting the rating. This is a current-swept site requiring advanced certification, and you'll be working an exposed reef corner — hook in firmly and respect the flow. Sea temperature sits between 28.9 and 29.4°C.

Divers commonly log grey reef sharks and whitetip reef sharks here, along with napoleon wrasse, hawksbill sea turtles, and harlequin sweetlips. Giant moray, moorish idol, and orangefin anemonefish are often recorded. The charter will brief you on the current and entry protocol — this dive demands solid buoyancy and a tight team.
