About Noirmoutier wave buoy
Noirmoutier is a CANDHIS directional buoy west of the low-lying island on the Vendée coast, operated within France's national in-situ sea-state observatory. Its position helps distinguish offshore Atlantic forcing from the sheltering and shallow-water effects around Noirmoutier and Bourgneuf Bay.
Its current data source reports wave height, wave period, wave direction, directional spread and sea temperature.
