Dive briefing

AI-generated

Conditions are poor today due to wind, with 1.6m effective waves compounded by local wind chop across this exposed site. Raw sea state is running 1.6–1.8m with wind waves adding 1–1.3m. This is an advanced dive in current-swept water; today's conditions will make it demanding. You'll need firm buoyancy control and a solid hook technique on the plateau. Sea temperature sits at 28.6–28.8°C.

Divers commonly log grey reef sharks and whitetip reef sharks here, along with napoleon wrasse, hawksbill sea turtles, harlequin sweetlips, orangefin anemonefish, moorish idols, and giant moray. The site lives up to its reputation for stacked marine life in the flow, though poor conditions will test your focus and air consumption.
