This advanced snorkel site, designated a Sanctuary Zone within the Southern Spencer Gulf Marine Park, offers an underwater playground of limestone swim-throughs, chimneys, caves, ledges and crevices in depths of 2–8 metres. At low tide, a line of reef either side of the island provides some protection from ocean swells. The site is renowned for eagle rays, southern rock lobsters, wobbegongs, Port Jackson sharks, and fiddler rays gliding through seagrass beds. Best attempted in calm conditions with light northerly winds — south winds make it unfishable.","advanced","https:\u002F\u002Fhowsthespot.syd1.cdn.digitaloceanspaces.com\u002Fspots\u002Fimport_chinaman-s-hat-chinaman-s-hat-island_0_a303013ae671.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],0.007621031807578392,0.011300914952530512,0.1992485926662375,0.04047955887137313,0.17412553873975664,0.0008152809513248643,0.00758359194444047,0.00957915922813476,0.010852417397814956,0.13898976650630793,0.05629041309776262,0.03449571639800346,0.017537266727395313,0.17227468009933097,0.01784841157020606,[53,54,55,56,57,58,59,60,61,62,63,64,65,66,67],183.1662377296591,276.04186228309436,255.9556938438563,182.31657892959748,129.6093255828497,195.34058382516525,120.63320425008243,253.50422845486656,200.71259031336325,239.4881987962188,256.48680778341225,223.02880769774902,3.2758043450976397,170.83827732719806,165.34060057670365,"EOT20","1992-01-01T00:00:00Z",[71,77,81,86,92,96,99,102,105,108,111,116,119,122,125,128,131,134,137,140,143],{"name":72,"description":73,"severity":74,"season_start":75,"season_end":76},"Ocean currents","A steady current runs across the island from left to right, requiring snorkelers to plan entry and exit points carefully.","warning",1,12,{"name":78,"description":79,"severity":80,"season_start":75,"season_end":76},"Open water exposure","This is an exposed open-water snorkel site with no sheltered bay, making conditions highly dependent on wind direction.","caution",{"name":82,"description":83,"severity":80,"season_start":84,"season_end":85},"Cold water temperatures","Water temperatures range 17–22°C year-round, with winter temps posing a risk of cold shock without adequate wetsuit protection.",5,9,{"name":87,"description":88,"severity":89,"season_start":90,"season_end":91},"Southerly wind hazard","When the wind blows from the south, the site becomes unsafe and unsnorkellable — forget entering the water under those conditions.","danger",4,10,{"name":93,"description":94,"severity":74,"season_start":95,"season_end":95},"Open ocean currents","Significant left-to-right currents run across the island; plan entry and drift accordingly.
