French seaside resorts offer late-season swimming in September

September offers continued opportunities for swimming at various French seaside destinations where water temperatures remain warm. Locations such as Corsica, the Mediterranean coast, and the Basque coast are highlighted as ideal spots for late-season coastal trips.

In the Pas-de-Calais region, Fort-Mahon-Plage is noted as a more affordable and calmer alternative to the popular resort of Le Touquet. Located approximately two hours from Paris via the A16, Fort-Mahon-Plage is described as a family-oriented and dynamic destination that caters to various budgets, unlike the more crowded and luxury-focused streets of Le Touquet.
