Information only

Good Buoy publishes indicative water-quality readings — sensor proxies, live CSO feeds and modelled plumes. It is nota substitute for the Environment Agency’s official bathing-water classifications, and it does not tell you whether to swim. Any decision to enter the water is yours alone. Check the EA bathing-water profile for the site you plan to use, consider recent rainfall and tide, and use your own judgement.
