About this swim spot
St Agnes is a sea swim spot on the ENG coast and one of around 2,000 UK swim spots Hattie Knows monitors continuously. Tide times, wave height and water temperature shape every sea swim — Hattie pulls all three from official UK Hydrographic Office and Met Office feeds.
Every Hattie verdict combines direct ingest from all 12 UK water companies' Event Duration Monitoring feeds, EA / NRW / SEPA / DAERA bathing-water samples, Met Office and Open-Meteo forecasts, UKHO tide tables, and live flood warnings — fused into a single read of whether it is safe to swim right now.
