Dive briefing

AI-generated

Conditions are poor today, with wind chop adding to a 1.4m effective wave height. The site runs 12 to 30 metres on rocky reef, so you'll need advanced certification and should be confident in exposed water. Water temperature sits at 21.5–21.7°C.

Divers commonly log sand tiger sharks and common blacktip sharks here, along with crustaceans including KZN river crabs and pink ghost crabs. Cape white seabream, convict surgeonfish, and lyretail anthias are also often recorded. Plan your dive with the current conditions in mind and stay aware of surge at depth.
