Nestled between tingle and karri forests, the beach faces the inlet rather than the open ocean, making it a safe, sheltered snorkelling environment. The beach is part of the Walpole-Nornalup Marine Park, with sandy-bottomed shallows and the tranquil inlet waters providing good visibility. Surrounded by five national parks, this spot combines pristine nature with easy access from the adjacent holiday park.","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],0.008830477086318563,0.009426526946910123,0.16710624125111823,0.022784042494323503,0.060406706662201944,0.002130100197801763,0.0025662172244006612,0.003499424244484239,0.02966558929187955,0.1275077808900456,0.046253768076959946,0.03366787609992915,0.009821871044804323,0.0768330278444933,0.0029762485352331797,[91,92,93,94,95,96,97,98,99,100,101,102,103,104,105],120.84361428410165,228.7206413071126,201.94918751893556,64.57476151911783,104.59830064144381,303.95138893350077,184.95825391490894,242.25358396350356,145.7042447971856,191.70416245285094,200.471945775476,184.20736339729115,329.20469944344734,82.8577438475512,158.3710806266896,"EOT20","1992-01-01T00:00:00Z",[109,114,119],{"name":110,"description":111,"severity":112,"season_start":113,"season_end":113},"Outgoing tide current","The Nornalup Inlet is connected to the Southern Ocean via the Irwin Inlet mouth.
