The River Thames in London has its first official bathing spot, designated as a bathing water area at Ham, in south-west London. The site opened on Friday, May 15, 2026, marking the start of the bathing season.
This is one of 13 new monitored swimming areas across England, according to the Environment Agency. The designation means water quality will be regularly tested for bacteria levels, with results published online.
The bathing spot is located on the River Thames near Ham House, a historic 17th-century mansion. Swimmers are advised to check water quality before entering, as the river can have variable conditions.
The move follows a campaign by local groups and the Port of London Authority, which worked to ensure safe access. The site is expected to attract both locals and tourists.
