The short walk from the carpark leads directly to the shoreline snorkelling area, making this a unique blend of wildlife sanctuary and urban-accessible snorkel spot in the heart of Coffs Harbour.","intermediate","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],0.030231031162135172,0.010290195956658133,0.1836260748811382,0.03034170623825693,0.5321336347642787,0.0034082720384775423,0.0034528663952923815,0.004221764748909751,0.11172305658489046,0.09600275208344942,0.05667522676548673,0.01903435166437405,0.01408953293725355,0.1359162100842811,0.007761272872987109,[91,92,93,94,95,96,97,98,99,100,101,102,103,104,105],290.7621929082268,359.4435822825069,341.6977531489764,290.02676293647147,302.7940740173632,301.40839335918946,193.29957403412158,353.52698590627034,295.7273413418975,314.72652037305585,341.0075990851734,279.8306471069171,319.8338882697451,314.5280600925784,340.77093237462884,"EOT20","1992-01-01T00:00:00Z",[109,114,118,121,124,128,131,134,137,140,143],{"name":110,"description":111,"severity":112,"season_start":113,"season_end":113},"Ocean swell and choppy surface conditions","Even on the sheltered side, swell and wind can create choppy conditions.
