A massive underwater wall runs more than a kilometre parallel to the island, rising from the sandy bottom at 22 metres up to about 10 metres. The wall is riddled with caves, swim-throughs, chasms and gorges, offering endless exploration. The sponge and soft coral coverage is breathtakingly colourful — vivid reds, yellows and oranges carpet the rock — and the fish life is abundant. This is a boat-access site best suited to intermediate to advanced snorkelers and divers due to open-water conditions and depth.","intermediate",null,"published",{"name":59,"amplitude":75,"phase":91,"latitude":22,"model":107,"epoch":108},[60,61,62,63,64,65,66,67,68,69,70,71,72,73,74],"2N2","J1","K1","K2","M2","M4","MF","MM","N2","O1","P1","Q1","S1","S2","T2",[76,77,78,79,80,81,82,83,84,85,86,87,88,89,90],0.008333828712513291,0.013844919707458499,0.2520427855441476,0.06484919382819854,0.1678641866312584,0.007162349536026899,0.003437349284504788,0.011458590479886293,0.010835922782786347,0.17267142792268725,0.07414402137172618,0.041203252558147614,0.013420073385603068,0.1839856110071967,0.014902557077668643,[92,93,94,95,96,97,98,99,100,101,102,103,104,105,106],199.41010350161054,293.86587710996804,267.96641741216865,192.83945275910014,147.63696876377307,306.75720706761587,156.73147343872245,256.71977047848156,231.15340092558267,250.58359910990168,265.4910404182248,233.41940790584164,342.41375971818167,189.6335881133623,174.08327439386164,"EOT20","1992-01-01T00:00:00Z",[110,116,120,123],{"name":111,"description":112,"severity":113,"season_start":114,"season_end":115},"Open-water swell","The site is exposed to open-ocean swell, which can cause surge around the wall and through swim-throughs.
