A fringing coral reef system hugs the shoreline, with coral bommies and sandy channels that host colourful reef fish, sea turtles, and rays. Part of the Great Barrier Reef Marine Park and Whitsunday Islands National Park, this peaceful anchorage is a favourite stop for luxury yacht charters exploring the Whitsundays. The bay's reliable calm conditions and close-to-shore reef make it one of the most accessible snorkelling locations in the region.","beginner",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],0.03143186743332736,0.022126411257208635,0.34521631235968187,0.08959924819895652,0.8981422107946567,0.012357405293679317,0.002272528622759663,0.005604982427587326,0.23045356633302175,0.17350887802395598,0.10473485045677217,0.03140300243663909,0.005085662987967782,0.31238274782756054,0.020206640382558965,[92,93,94,95,96,97,98,99,100,101,102,103,104,105,106],353.0966775544043,50.47374000234436,37.76533371360009,347.2294143804188,21.74756845298752,75.49052368694454,52.5125033152062,178.1179956589572,2.296619577730113,10.381884646057376,33.26019018523349,344.00384015458786,334.9335758420687,349.55985705789146,307.81546549435114,"EOT20","1992-01-01T00:00:00Z",[110,114,117,120,124,127],{"name":111,"description":112,"severity":113,"season_start":56,"season_end":56},"High tide coral visibility","Coral bommies may be challenging to locate at high tide, increasing risk of disorientation or accidental coral contact.","caution",{"name":115,"description":116,"severity":113,"season_start":56,"season_end":56},"Reef sharks in deeper water","Small reef sharks are occasionally observed in deeper water areas; generally harmless but may startle swimmers.",{"name":118,"description":119,"severity":113,"season_start":56,"season_end":56},"Vessel traffic","Boat traffic from charter yachts and tenders entering and leaving the bay.",{"name":121,"description":122,"severity":113,"season_start":36,"season_end":123},"Marine stingers (jellyfish)","Stinger season in tropical Queensland waters; marine stingers (jellyfish) may be present.",5,{"name":125,"description":126,"severity":113,"season_start":56,"season_end":56},"High tide submerged bommies","The best coral bommies are located in the centre of the bay and can be difficult to locate at high tide when water levels obscure reef structures.",{"name":128,"description":129,"severity":113,"season_start":56,"season_end":56},"Marine traffic and mooring lines","Vessels must use public moorings to avoid anchor damage.
