Nantwich Leisure Centre's open-air saltwater swimming pool in Cheshire is experiencing a significant surge in demand, with management reporting that sessions are being booked up to eight days in advance. Peter Wilson, the general manager, stated that the facility has been "extremely busy" during recent heatwaves, leading to unbooked visitors being turned away.
The unique attraction, capable of accommodating 147 swimmers per session, is drawing visitors from a wide geographical area. Mr Wilson noted that customers are travelling from "all over the north west of England, Midlands and North Wales," a pattern observed annually, but intensified by the current warm weather conditions.
First opened to the public on 1st July 1935, the Nantwich pool holds a special place in UK leisure history. It is believed to be one of only two inland open-air brine swimming pools remaining in the country, the other being located in Droitwich, Worcestershire. The pool's water temperature typically hovers around 22°C (74°F) and it commenced its 2026 season in April.
The increased popularity aligns with a broader trend of growing interest in outdoor swimming, which Mr Wilson attributes partly to a focus on mental health benefits. He observed a return to "traditional lidos," indicating a wider appreciation for outdoor aquatic facilities. Despite its long history and unique status, Mr Wilson also mentioned that some local Nantwich residents remain unaware of this "little hidden gem," often surprised by the pool's size when they first visit.
The current demand is further amplified by the UK's third heatwave of the year, which is set to intensify this week. Temperatures in parts of England and Wales are forecast to exceed 30°C, prompting the UK Health Security Agency to issue amber and yellow heat health alerts. This sustained period of warm weather is undoubtedly contributing to the allure of open-air swimming facilities like the Nantwich pool.
