Dunster Beach was rated Poor for 2025 — below the minimum standard, based on samples taken across recent seasons. That grade comes from bacterial samples taken over several seasons, so it describes the beach's record rather than the water on any given day.
The Environment Agency issues a pollution risk forecast for this beach every morning during the bathing season, and the water company publishes the status of its storm overflows every few minutes.
The regulator records this as a bathing water whose quality can be affected by heavy rain, which is why rainfall in the last 24 hours is shown above.
