The reward for tackling the notorious rips and surge is uncrowded waters, shipwreck relics, and encounters with wrasse, rays and Port Jackson sharks. This is advanced-level snorkeling for experienced water-goers only, best attempted on low tide after days of northerly winds.","advanced","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],0.01518292922640474,0.01472168794339704,0.2155732427365139,0.047741180988985624,0.7146294438004043,0.0485776342591161,0.006695082368918923,0.006271020015272035,0.14601752475277144,0.15123126870810275,0.06594009495004506,0.03337316900793892,0.013468462951739814,0.20394125347557102,0.021713807928545815,[91,92,93,94,95,96,97,98,99,100,101,102,103,104,105],302.1631015167527,298.7176095127919,271.3918072985951,156.97924453406665,31.38161022641543,141.6326019564649,171.65689595655897,233.23454694124558,351.7257123300841,251.3588879870997,263.4414581883648,241.78128985020675,0.8177182716631818,156.54102600930918,161.48724200406718,"EOT20","1992-01-01T00:00:00Z",[109,114,117,121,125],{"name":110,"description":111,"severity":112,"season_start":36,"season_end":113},"Strong Rip Currents","All Back Beach sites are rip-prone due to shallow reefs and ocean swell.
