The Environment Agency has added a precautionary bathing warning for Dymchurch on top of the long-standing poor-water-quality notice already in place — meaning the beach now carries two separate advisories against swimming.

What the warning means for swimmers and families

Folkestone & Hythe District Council posted the news on social media, confirming that anyone planning to swim or paddle at Dymchurch should stay out of the water while the notice is in force. The beach itself remains open — you can still walk it, sit on it, and let children play on the sand — but entering the sea is not advised. That distinction matters, especially for families visiting during the summer season.

Two warnings, one beach

The new notice is precautionary, issued following a confirmed sewage effluent spill into the Hoorne Sewer. But it sits alongside a separate warning that was already there — Dymchurch’s bathing water was classified as Poor in the Environment Agency’s 2024 results, the lowest possible rating. So this isn’t simply a one-off bad day at the beach. It’s an additional layer of concern on a stretch of coastline that has struggled with water quality for some time.

Dymchurch is one of six designated bathing waters in Folkestone & Hythe District, alongside Folkestone, Sandgate, Hythe, St Mary’s Bay and Littlestone.

A wider problem along the Romney Marsh coast

Dymchurch isn’t alone. St Mary’s Bay has held a Poor classification since 2022, and Littlestone since 2023 — both already subject to advice against bathing. The Environment Agency has said in Parliament that Dymchurch and St Mary’s Bay are priority bathing waters, and that it is working with Southern Water, the local authority and communities to improve water quality. While the specific notice issued this week followed an identified sewage spill, no single long-term pollution source has been definitively established as the cause of Dymchurch’s ongoing Poor classification, with investigators continuing to look at sewage-related inputs and other contamination sources.

The case for and against the warning

The council’s position, in line with Environment Agency guidance, is that a precautionary notice protects public health when conditions can change quickly and sewage pollution is possible. Official warnings also help residents and visitors make an informed choice — particularly where a Poor classification already exists.

But the warnings carry a cost. Local businesses that depend on seaside footfall risk losing trade if visitors decide the water isn’t worth the risk. And for many in Dymchurch, the frustration runs deeper than any single notice. The pollution sources haven’t been fully resolved or clearly pinned to one cause, and the repeat nature of these warnings — season after season — raises questions about how quickly meaningful action will follow.

What to do before you visit

A Poor classification does not close the beach. But it does mean the Environment Agency recommends people do not swim there. Anyone travelling to Dymchurch this season should check the current bathing-water status before they go, as conditions and notices can change.
