Unlike platform reefs closer to shore, these ribbon reefs rise steeply from deep Coral Sea waters, creating a dramatic split: sheltered inner lagoons with coral gardens on one side and a vertical wall plunging into the open ocean on the other. Constantly flushed by pristine oceanic currents, the water clarity regularly exceeds 20 metres, making it one of the best snorkelling destinations in the world. The reef system comprises multiple smaller ribbon reefs running parallel to the continental shelf, offering diverse terrain from shallow coral gardens to bommies, channels, and swim-throughs.","beginner","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],0.024406269790941477,0.020954750795731423,0.30862784382981273,0.0856116449892507,0.505307782938539,0.0002616614374408121,0.010474176810028525,0.009948986576974872,0.17432385575096132,0.14889355283441116,0.08941679980983194,0.024163626890297458,0.010530498211694207,0.2996919139524238,0.02638025048965533,[91,92,93,94,95,96,97,98,99,100,101,102,103,104,105],318.3337409337706,48.51896453574723,40.293201890487225,298.02720225030293,343.5404103921592,100.67085685462393,6.47448136866693,41.23079485060104,327.89311199200085,10.784034222556583,37.371395717123995,359.730909481437,353.5420329804452,303.53206507112725,278.835902905082,"EOT20","1992-01-01T00:00:00Z",[109,114,118,121,124,129,132,135,138,141,145,148,151,154],{"name":110,"description":111,"severity":112,"season_start":36,"season_end":113},"Open Ocean Crossing (Seasickness)","The 90-minute open-water catamaran crossing from Port Douglas can be rough for those prone to seasickness, especially in windy conditions.
