Operational Wave and Water Model (OWWL)

Operational Wave and Water Model Logo

Coastal floods occur when big tides coincide with storms, producing a storm surge.

The Operational Wave and Water Level Forecast Model uses the latest weather forecasts and wave measurements to forecast coastal floods, it is free for anyone to sign up.

The model is regularly updated with our beach survey profiles, measured (up to) twice a year, it also integrates real-time wavebuoy and Met Office readings to forecast coastal flooding (wave and water level overtopping).

It has been operational in S.Wales since November 2020.
