About Île de Batz wave buoy
Île de Batz is a CANDHIS directional buoy off northern Brittany, within the French national sea-state observatory coordinated by Cerema. The station sits at the western entrance to the English Channel, where Atlantic swell rounds Brittany towards the exposed Finistère and Channel coasts.
Its current data source reports wave height, wave period, wave direction, directional spread and sea temperature.
