The Saint-Jean-de-Monts resort, as most of the Vendée seashore, benefits from a privileged climate recognized by Meteo France as a "micro-climate". The geographical location between two low-pressure systems, and the Gulf Stream leverage, grant the sunshine of the Vendée coast and confer as much sunshine hours as the mediterranean departments. For statistical information: Saint-Jean-de-Monts reaches the same amount of sunshine hours as Carcassonne and rises above the South West towns like Biarritz.
