About Penarth wave buoy

Penarth is a Channel Coastal Observatory non-directional wave station in the upper Bristol Channel off the Vale of Glamorgan. Its ten-minute record captures the short-period sea state near Cardiff Bay and Penarth in shallow, strongly tidal waters with a restricted Atlantic fetch.

Its current data source reports wave height and wave period.
