This remote reef pinnacle features dramatic walls dropping into deep ocean waters, with a sloping coral shelf starting at around 12 metres and tumbling into the abyss. The site is renowned for encounters with large pelagic marine life — grey reef sharks, giant trevally, and seasonal minke whales — as well as stunning coral gardens on the upper slopes. Because of its open-ocean exposure, South Horn delivers exhilarating drift snorkels and world-class visibility, but demands confident swimmers and favourable conditions.","advanced",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],0.02652589691570588,0.020574692477017726,0.3023731594781675,0.08399203957745008,0.5132956326837153,0.00415297675834714,0.012999584630337228,0.010975077292301835,0.1739646513583627,0.14427524735470873,0.09229612586379032,0.026922894602129148,0.005324360590135017,0.299480205259988,0.022188044739857415,[92,93,94,95,96,97,98,99,100,101,102,103,104,105,106],327.2751954145143,50.99837216562125,40.25386923871924,301.89077920021714,346.59741621925997,198.48266440749273,11.384867640476536,32.11726258682711,329.98459812199985,12.07116717714707,35.90011499692933,356.76603488250424,294.06164996397297,305.8711762054529,284.8503211937163,"EOT20","1992-01-01T00:00:00Z",[110,115,118,122],{"name":111,"description":112,"severity":113,"season_start":36,"season_end":114},"Strong tidal currents","Strong currents sweep across the exposed outer reef face, particularly on the ebb tide.
