These are considered the finest examples of oceanic atolls in Australian waters, each encircling a shallow turquoise lagoon with sheer vertical drop-offs plunging into deep blue water. With over 214 species of hard coral and 530 species of fish, the park offers world-class drift snorkelling through coral gardens, gin-clear lagoons, and channels shaped by powerful tidal flows. Mermaid Reef is a strict no-take National Park Zone, while Clerke and Imperieuse feature sandy cays where white-tailed tropicbirds breed. Access is exclusively by live-aboard cruises from Broome between September and December.","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],0.017545754477914628,0.013539595509802414,0.2289233590975338,0.15204246240208655,0.9704971479340829,0.004805832098869492,0.00965191894207584,0.003887184204229112,0.17456857493817235,0.14346734619237922,0.06650536765631869,0.03287896878019795,0.011610005950474653,0.5538326536668368,0.028057577430350696,[91,92,93,94,95,96,97,98,99,100,101,102,103,104,105],2.200128809334067,181.18125269091288,168.14766561965538,114.76051585435059,57.983706769423954,226.0359795621836,353.7506402012636,2.5882304554399345,31.50831372228642,158.72497958056587,165.54015901577972,148.6905043219716,350.13474885903446,116.13143905138712,128.3419736269839,"EOT20","1992-01-01T00:00:00Z",[109,114,118,123,127,131,134,137,140],{"name":110,"description":111,"severity":112,"season_start":36,"season_end":113},"Strong tidal currents","The Rowley Shoals experience dramatic tidal movement with up to 4-5 metre tidal ranges.
