French authorities have made the unusual decision to temporarily allow swimming in the Seine River in the Paris region due to an ongoing heatwave. Exceptionally high temperatures have prompted the measure, offering residents and tourists a respite from the heat. The lifting of the long-standing swimming ban applies to designated areas along the river. Water quality has reportedly improved significantly in recent years, making this temporary allowance possible. Officials are still advising caution and will monitor water conditions closely. The move aims to provide accessible cooling options as temperatures continue to soar, with further heat alerts expected.
