This remote, rocky island sits at the convergence of tropical and temperate waters, creating a biodiversity hotspot with over 550 fish species and 90 coral types. Snorkelers are treated to dramatic granite boulder formations, kelp gardens, and subtropical corals in crystal-clear oceanic water. The island's isolation and marine-park protection mean exceptional water quality and abundant marine encounters with grey nurse sharks, blue groper, turtles, and wobbegong sharks patrolling the reef edges. Popular among experienced snorkelers, tours depart from Coffs Harbour.","advanced","https:\u002F\u002Fhowsthespot.syd1.cdn.digitaloceanspaces.com\u002Fspots\u002Fimport_manta-arch-south-solitary-island_0_e4828f1157b5.jpg","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],0.027622191088200427,0.009462986857146504,0.1845781085593742,0.03295453165869725,0.5348428648759238,0.0035332477886009387,0.0037482144690996065,0.004455835941621485,0.11260719994197133,0.0950179336597034,0.05713772374081152,0.02037600129946987,0.012790166756656377,0.13985929400880653,0.010742296303738482,[53,54,55,56,57,58,59,60,61,62,63,64,65,66,67],293.40998386937645,4.946275042522785,342.3693388859641,294.14988543765924,302.61018541460015,283.17016641085957,200.774380209987,18.71726140342483,295.17276167845904,315.1902759200082,341.3618108885463,278.1607796869888,316.66500301899134,314.28924920925635,340.02644466828986,"EOT20","1992-01-01T00:00:00Z",[71,76,80,83,86,91,96,99,102,107,111,114,117,120,123],{"name":72,"description":73,"severity":74,"season_start":75,"season_end":75},"Open ocean swell and surge","Surge is common shallower than 10m and can be strong on spring tides or during southerly swells.
