Beginners can explore the central bay's seagrass beds at 1–3m depth, spotting cowfish, pufferfish, and crustaceans amid rocky swim-throughs. More advanced snorkelers can head to the outer reef (3–8m) where limestone formations create underwater valleys hiding octopus and weedy seadragons. Beyond the yellow marine buoy lies deeper open water (7m+) where dolphins and seals occasionally pass through. Best visited December–March when water temperatures exceed 20°C and winds are calm, the reef offers crystal-clear conditions on quiet mornings.","intermediate",null,"published",{"name":20,"amplitude":36,"phase":52,"latitude":13,"model":68,"epoch":69},[21,22,23,24,25,26,27,28,29,30,31,32,33,34,35],"2N2","J1","K1","K2","M2","M4","MF","MM","N2","O1","P1","Q1","S1","S2","T2",[37,38,39,40,41,42,43,44,45,46,47,48,49,50,51],0.004138255641140625,0.009100934676354215,0.16712810092975103,0.014615285462913732,0.05287839209855107,0.004532580355073513,0.0043761610059752445,0.004658670296748399,0.01395122398217303,0.12144491362904936,0.05124507917871472,0.023338793184845205,0.012680799720642446,0.0411397135029236,0.00262858239039233,[53,54,55,56,57,58,59,60,61,62,63,64,65,66,67],51.440990170955466,224.07046495493967,181.38993203477355,34.1184239872897,57.3134776224858,139.95715412737724,28.57387552934816,232.08145044492517,108.19639413611452,175.70225030214988,170.9042552168189,172.95596287067735,321.16277221407677,61.83143503496228,245.3368145548592,"EOT20","1992-01-01T00:00:00Z",[71,76,80,84],{"name":72,"description":73,"severity":74,"season_start":75,"season_end":75},"Outer reef swell and surge","The outer portion of the reef can have significant swell, surge, and waves that challenge even experienced snorkelers.","warning",12,{"name":77,"description":78,"severity":79,"season_start":17,"season_end":17},"Sharks in open water","Hammerhead, bronze whaler, and bull sharks are known to frequent the deeper water beyond the yellow marine buoy (7m+ depth, up to 1km offshore).","danger",{"name":81,"description":82,"severity":83,"season_start":17,"season_end":17},"Poor visibility in windy conditions","Visibility drops significantly when wind exceeds 10 km\u002Fh or swell is above 1m.
