Common questions

Where can you swim near London?
5 sea, lake and river swimming spots lie within 30 km of London, spread across 3 areas. This page lists them by distance from the town rather than by county, because a boundary is not what decides where you drive.
What is the nearest beach to London?
The Serpentine - Hyde Park in City of Westminster, about 3 km away. It is the closest of the 5 listed here; the next few are within a short drive and each shows its current status, so the nearest is not always the one to pick.
Is the water clean near London?
5 of these 5 spots are designated bathing waters with published monitoring, from the Environment Agency (England). Monitoring covers bacterial quality only — it says nothing about tides, currents, swell or cold-water shock, and nothing here is a clearance to swim.
Which spots near London have the best water quality?
2 of them hold Excellent, the top classification under the EU Bathing Water Directive, based on bacterial samples across the previous four bathing seasons. That describes a four-year record rather than the water today — each spot page shows both.
Can you swim near London right now?
1 of the 5 is currently flagged, including 1 under an active do-not-swim notice, and 4 have no current pollution alert. These change day to day, so check the individual spot before you travel.
