London and parts of the UK face a rare red weather warning for extreme heat, with temperatures forecast to reach around 40°C on Wednesday. With many people seeking ways to cool down locally, London’s lidos, ponds and outdoor pools are highlighted as key summer options. One outlet focuses on Park Road Lido in Crouch End, describing it as a council-run pool dating from 1926 and noting that ticket availability varies by time slot during the heat. It states the lanes are for people aged 12 and above, with family slots for parents with children, and says adult admission is £9.95 with advance booking available, while Friday evening still shows availability. Another outlet provides a broader list of places to swim across the capital during the same heat period. It includes Tooting Bec Lido (described as reopened after a major revamp and with set daily sessions), Hampstead Heath Ponds (wild swimming, with a pay-and-go ticket structure), Brockwell Lido (50-metre pool open daily with advance lane bookings), Charlton Lido, Parliament Hill Lido, Hackney West Reservoir, Beckenham Place Park, Serpentine Lido, and Hillingdon Lido, alongside notes on indoor backup options such as Finchley Lido Leisure Centre.
