A bathing water's official classification is calculated from percentiles across four bathing seasons, not from any single sample — so one high reading doesn't mean a spot is unsafe, and one low reading doesn't mean it's clean today.

Storm overflows nearby
None of the storm overflows within 5 km with an up-to-date reading are discharging. Heavy rain makes combined sewers overflow into rivers and the sea by design, so this changes with the weather.

These are the water company’s own reports of when an overflow is operating, not a measurement of the water at this spot. A discharge into a river some distance away may never reach here; a quiet list does not mean the water is clean. The swim status above comes from the bathing-water monitoring body and does not use this data.
