About this swim spot
Arundel is a tidal-river swim spot on the England coast and one of around 2,000 UK swim spots Hattie Knows monitors continuously. Tidal rivers behave like both — the daily tide governs depth and current, while upstream rainfall and sewage discharges still reach you. Hattie monitors both.
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.
