The rocky groin structure is the focal point — it attracts schooling fish, soft corals, and offers depths to 10 m within metres of shore. The bay's protected waters make it a reliable fallback when other sites are windy, with good visibility after calm weather. A popular shore-entry spot for both snorkellers and divers seeking accessible underwater terrain.","intermediate","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],0.004069325823909827,0.009580000548645941,0.16611524296546198,0.014440773295855464,0.054810839874245496,0.004814749443883301,0.004811842523596494,0.004765109170341946,0.013737111875289554,0.12162132956348988,0.05054214454923644,0.02301955323559473,0.015695631430451714,0.04187806720123667,0.002783104438818689,[91,92,93,94,95,96,97,98,99,100,101,102,103,104,105],42.10913576643702,226.59353320467483,181.78257235747367,35.716919813675986,58.15611909694036,137.3296854619773,31.286949502097734,226.83045619214965,106.35504050734063,176.18030674893157,170.98156153344047,173.28370864095223,311.95285072805956,62.99541932275986,232.04190429418964,"EOT20","1992-01-01T00:00:00Z",[109,114,117,121,124],{"name":110,"description":111,"severity":112,"season_start":113,"season_end":113},"Outgoing tidal current","The main hazard is a strong tidal current that can run along the groin, especially on an outgoing tide.
