About Weston Bay wave buoy

Weston Bay is a National Network Datawell Directional WaveRider in the upper Bristol Channel off Weston-super-Mare. Deployed in September 2009, it builds a record in a shallow, strongly tidal estuary where extensive intertidal flats and a limited seaward fetch influence the local sea state.

Its current data source reports wave height, wave period, wave direction, directional spread, wave power and sea temperature.
