The wall is draped in vibrant corals — massive gorgonian sea fans, branching red fan corals, and colourful soft corals leaning outward to catch the tropical sunlight. Fusiliers school up and down the wall in shimmering curtains, while angelfish, butterflyfish, and featherstars cling to the coral-covered face. The dive starts beneath a shallow cave overhang decorated with sea fans, before the seafloor drops away dramatically. Dolphins are frequently spotted before you even enter the water, making this one of the most spectacular reef wall experiences in the Indian Ocean.","intermediate",null,"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],0.01146541373472437,0.008394413770725037,0.18022186060952372,0.045513664248235504,0.3550984723132339,0.004995755389218793,0.014906602473981604,0.008839229774851926,0.07954978409064035,0.11128788019478826,0.05500920407744663,0.021971491809396667,0.005076354758181179,0.15730694663140887,0.008202077903466958,[91,92,93,94,95,96,97,98,99,100,101,102,103,104,105],318.8923426153823,180.7366679376389,161.0917635846829,57.32611830153576,7.957895201928751,343.85744664873766,12.941598683909117,350.72408520454326,338.8252486345192,153.9945635722878,157.35944630859342,143.03240082073526,275.8683734064615,70.91572312922727,297.8379859456942,"EOT20","1992-01-01T00:00:00Z",[109,114,117],{"name":110,"description":111,"severity":112,"season_start":35,"season_end":113},"Ocean currents","Strong currents can sweep along the north coast wall, requiring good finning technique and awareness.","warning",12,{"name":115,"description":116,"severity":112,"season_start":55,"season_end":55},"Deep drop-off \u002F depth hazard","The wall drops to significant depths (&gt;30m) — snorkelers should stay close to the surface and avoid free-diving beyond their limits.",{"name":118,"description":119,"severity":120,"season_start":55,"season_end":55},"Swell \u002F rough sea conditions","Swell from the Indian Ocean can create challenging conditions on the exposed north coast, especially during the wet season.","caution",{"directions":122,"parking":123,"facilities":55,"fees":124,"access_method":125},"Perpendicular Wall is located off the north coast of Christmas Island, accessible only by boat from Flying Fish Cove or the main jetty.
