Installed each spring (Oct–Mar), the barrier encloses a calm, protected zone where snorkelers can drift alongside schooling silver fish, bullseyes, and juvenile Australian salmon amid sandy patches and low limestone reef. The adjacent groyne attracts extra marine life, and the crystal-clear Indian Ocean waters make this a family-friendly snorkel spot with excellent visibility. Located just steps from the grassy Cottesloe foreshore, it offers a safe alternative to the open ocean while still delivering that classic white-sand beach experience.","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],0.004246646050641868,0.00929715593939091,0.16671990024248595,0.013763551056940972,0.05442926686434654,0.004831037571235754,0.005031046440380575,0.004593391224684983,0.013459586396300377,0.12210902263225695,0.05066823186019397,0.023037956390366602,0.013620958504661312,0.04165109266427433,0.002988107938348202,[92,93,94,95,96,97,98,99,100,101,102,103,104,105,106],38.07168459976013,226.5547116816707,181.76307460570933,39.03973987574349,58.69595906491372,131.53454162642942,33.33911075183571,222.96465763182368,105.85905092868404,176.01364000372735,171.0963195429075,173.02286853875765,319.8592487484466,64.23281584403975,227.84649155086737,"EOT20","1992-01-01T00:00:00Z",[110,114,118,121,124,129,132,135,138],{"name":111,"description":112,"severity":113,"season_start":56,"season_end":56},"Boat traffic outside shark net","Vessels operate beyond the eco‑barrier; swimmers outside the net should remain vigilant.","caution",{"name":115,"description":116,"severity":113,"season_start":36,"season_end":117},"Limpets and barnacles on groyne","Sharp encrusting growth on the groyne rocks can cause cuts.",12,{"name":119,"description":120,"severity":113,"season_start":56,"season_end":56},"Strong south-westerly sea breeze","Afternoon sea breezes can whip up chop and reduce visibility, especially in summer.",{"name":122,"description":123,"severity":113,"season_start":36,"season_end":117},"Variable visibility","Visibility fluctuates with swell and wind; murky after storms or large swell.",{"name":125,"description":126,"severity":113,"season_start":127,"season_end":128},"Seasonal barrier removal","The Eco Shark Barrier is only installed between October and March (spring to autumn).
