The water
Six sites, chosen on the morning.
Six sites in regular rotation around Grande Island, including Umah Gumah Reef, the Grande Plateau and Sail Rock, a pinnacle dropping to 22m for certified divers only. Which you get depends on visibility and swell on the morning, not on a schedule printed in advance.
November to February brings the best visibility, 12–18m, and calm seas. March to May is the warmest water, with 8–14m. June to September is the monsoon, and we are closed.
