About Belle-Île wave buoy
Belle-Île is a CANDHIS directional buoy south of Brittany, maintained through the Cerema-coordinated sea-state observatory and research partners. Its open Atlantic position represents conditions approaching Belle-Île and the sheltered-to-exposed transition along the Morbihan coast.
Its current data source reports wave height, wave period, wave direction, directional spread and sea temperature.
