Dive briefing

AI-generated

Conditions are poor today due to wind. Seas are rough with local wind chop on top of the baseline swell, making this a challenging day for an intermediate diver. Water temperature is steady at 23.9–24.0°C. If you do go in, depths run 10–25 metres across the site.

Divers commonly log leopard coralgrouper and potato rockcod here, along with Pacific bullethead parrotfish, spiny chromis, and bridled monocle bream. Whitetip reef sharks are often recorded. You may also encounter scissortail sergeant and sixband angelfish. Consider waiting for calmer conditions if you have the option.
