The fringing reef sits just off the beach and extends the full length of the bay, wrapping around the southeastern point. Snorkelers swim out from the sandy shore at mid-to-low tide to explore the edge of the reef slope, where juvenile coral colonies, sea turtles, and colourful anemones thrive. Best visited in northerly or easterly wind conditions, this secluded spot offers a wild, uncrowded reef experience away from the main ferry beaches.","intermediate","published",{"name":58,"amplitude":74,"phase":90,"latitude":22,"model":106,"epoch":107},[59,60,61,62,63,64,65,66,67,68,69,70,71,72,73],"2N2","J1","K1","K2","M2","M4","MF","MM","N2","O1","P1","Q1","S1","S2","T2",[75,76,77,78,79,80,81,82,83,84,85,86,87,88,89],0.04577391352564322,0.021807398854145323,0.30423230576322474,0.14753484267015698,1.4073190560633768,0.006896505144833558,0.004216340982065919,0.003610062744562426,0.3111816862530274,0.15254912124415515,0.0869918523503894,0.02404206118918609,0.012549135683549213,0.4690954107887971,0.026440658304135077,[91,92,93,94,95,96,97,98,99,100,101,102,103,104,105],323.896794808192,35.87309735020849,13.533008674725123,345.4627755095353,353.6857796231403,14.467800675763531,15.342793815290669,113.99183924502579,343.9344880944243,345.2363812122604,9.694029522363733,309.07120335100626,315.0709476014041,352.39533283084853,329.90337523160804,"EOT20","1992-01-01T00:00:00Z",[109,114,118],{"name":110,"description":111,"severity":112,"season_start":43,"season_end":113},"Wind-exposed in southerly conditions","Best snorkeling conditions are during northerly or easterly winds.
