Dive briefing

AI-generated

Conditions are poor today. The short-period chop is making for a choppy, uncomfortable dive. Wave heights are running 0.6 to 0.8 metres raw, with periods between 3.8 and 4.7 seconds — the short intervals are what's driving the poor rating. This is an exposed site and it doesn't take much swell to close it out; you'll want to assess conditions carefully before committing.

Water temperature sits at 27 to 27.2°C. If you do get in, divers commonly log ornate wrasse, Mediterranean damselfish, European parrotfish and painted comber around the site. You're an intermediate diver working the arch and drop-through, so you'll have plenty to occupy you. Just be prepared for the conditions to feel lively.
