About Dawlish wave buoy

Dawlish is a Channel Coastal Observatory National Network wave station in the western part of Lyme Bay off south Devon. It provides nearshore context for waves reaching the Dawlish and Teignmouth frontage, including the exposed coastal railway and beaches backed by cliffs and urban development.

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