Forecast data: Open-Meteo. Water-quality classification, latest sample date and pollution-risk forecasts: Environment Agency. Storm-overflow status: National Storm Overflow Hub / Stream open data. Surf height is a Kernow Way spot-specific estimate derived from modelled swell, swell period, direction and local beach calibration. Tide times are modelled estimates for surf planning only and must not be used for navigation. Water-quality and storm-overflow indicators are informational and do not guarantee that the water is safe to enter. Local water-quality and overflow reports use data identified within a 2 km radius of each beach. Kernow Way provides Cornwall surf and beach data for Sennen Cove, Porthmeor, Gwithian, Perranporth, Crantock, North Fistral, South Fistral, Towan, Great Western, Lusty Glaze, Porth Beach, Watergate Bay, Harlyn Bay, Polzeath, Trebarwith Strand, Whitsand Bay, Porthleven and Gyllyngvase.
