The turquoise, sheltered waters around the river mouth are fed by daily tidal movements, creating a calm, estuary environment with sandy patches and seagrass beds to explore. The surrounding red Tumblagooda sandstone cliffs contrast brilliantly with the clear aquamarine water, while dolphins occasionally cruise past at sunset. This is a family-friendly spot where the saltwater from the ocean mixes with the freshwater outflow, providing a gently dynamic snorkeling setting.","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],0.0032666129250981256,0.00976882559250973,0.17237247208899228,0.013278131657507707,0.08760409391056966,0.012205734122370023,0.011823597811419726,0.0027725915356063744,0.022686702496759175,0.12752979858655974,0.05030017865034835,0.026833794949099918,0.017240566648932764,0.03961181738704039,0.0026402848380020745,[91,92,93,94,95,96,97,98,99,100,101,102,103,104,105],66.91710752595861,206.17571222556398,178.34634877950907,36.34276547260771,55.253414255464406,151.09796544522533,18.953016182972505,119.66267484525895,86.45898501188123,172.1471648414763,175.48396499451366,168.42410311815482,25.56752971100798,77.42737486142511,329.8107677778153,"EOT20","1992-01-01T00:00:00Z",[109,114,117,120,124,127,130,134,137],{"name":110,"description":111,"severity":112,"season_start":113,"season_end":113},"Outgoing tide current","When the tide ebbs, water flows from the estuary out to sea, creating a noticeable current near the mouth.
