As heatwaves persist across France, authorities and residents continue to utilize various natural swimming locations for relief. In Toulouse, the city council is reassessing the long-term feasibility of allowing public swimming in the Garonne River. While municipal studies address safety, water quality, and infrastructure challenges, swimming in the Garonne remains prohibited. Instead, the city promotes supervised sites such as Toulouse Plages, La Ramée, Muret Plage, L’Orme Blanc at Caraman, and Lac de la Thésauque through late August.

Regional cooling spots remain popular, including the historic Hanau Pond in Philippsbourg and supervised locations near Angers, such as Villevêque beach, Parc des Sablières, and Lac du Maine. 

By late August, natural sites with varying temperatures have been highlighted for their cooling properties. Near Toulouse, the Touch and Save rivers—fed by Pyrenean snowmelt—and the recently reopened Gorges de la Save offer cooler options. In the Alps, Lac d'Aiguebelette in Savoie provides warmer waters up to 28°C, though thermal motorboats are prohibited to maintain tranquility. High-altitude sites like Étang de Lers in Ariège also offer relief through cold spring feeding and slower evaporation.
