About Chesil wave buoy
Chesil is a Channel Coastal Observatory National Network wave station off Dorset's exposed Jurassic Coast. It records waves approaching Chesil Beach and the western side of Portland, providing a nearshore reference for the long shingle barrier and the communities and infrastructure behind it.
Its current data source reports wave height, wave period, wave direction, directional spread, wave power and sea temperature.
