Ranges span today's hours. Wave height here is the raw sea state — the rating scales it for how exposed the site is. Semi-exposed — partial protection, so swell is scored at three-quarters of its open-water height.

Dive briefing

AI-generated

Conditions are poor today, with short-period chop making for an uncomfortable day on the water. The limiting factor is wave period — you'll feel the energy of the swell compounded by wind-driven chop, which creates a rougher ride than the headline numbers suggest. This is an intermediate site in semi-exposed water, so surface conditions will feel the effects.

Divers commonly log leopard coralgroupers, potato rockcod, and whitetip reef sharks here. Parrotfish, chromis, and various smaller reef species are often recorded as well. Water temperature sits at 24.8–24.9°C. If you do dive today, be prepared for uncomfortable conditions on entry and exit.
