Visibility is consistently excellent year-round, making it a premier snorkel destination.","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],0.01752376747829474,0.010686818889305082,0.19058230784253413,0.047183073739646524,0.5520425852559149,0.004483099538295793,0.0012980999786457055,0.0008520402282178846,0.1193491064278382,0.10011730932474203,0.0590748614240488,0.019074194638427723,0.006521962956115165,0.1634293200024392,0.012768044557574954,[92,93,94,95,96,97,98,99,100,101,102,103,104,105,106],288.9380649894177,6.753859786856397,357.2198090777897,295.5047386651854,301.5027670041414,264.3601225938808,76.59349292809844,267.0921248724515,292.2117478663747,332.66963953187513,348.4090260089779,318.2365640808004,295.4983352295998,309.2658412596847,250.5231825969003,"EOT20","1992-01-01T00:00:00Z",[110,114,119,123],{"name":111,"description":112,"severity":113,"season_start":56,"season_end":56},"Boat traffic","Access is by boat from Mooloolaba and other vessels use the area.
