Safety is excellent with short runs to sheltered leeward sites and 24-hour chamber access in George Town. Conservation is robust with expanded marine parks and regulated wildlife interactions.
Cayman Hyperbaric Services operates the island's recompression chamber at the Cayman Islands Hospital in George Town with 24/7 on-call availability. For dive emergencies, call local EMS via 911, then contact DAN's 24/7 hotline.
Winter north swells
Dec to Mar cold fronts send swell to the North Wall and Seven Mile. Expect site changes or cancellations on short notice.
Ironshore and surge
Many shore entries are over ironshore with ladder access. Wear sturdy booties and plan exits if surge rises.
Sun and dehydration
Heat and humidity spike Aug to Oct. Hydrate, shade up, and watch exposure between dives.
Do Not Do This
Avoid entering when winter north swells. Confirm local briefings before committing.
