Beaufort Wind Scale - Weather Prediction Center

WebSwell. Wind waves are a local manifestation of the energy that has been transferred to the sea from the wind. This energy travels downwind away from the source area, rather like ripples in a pond when a stone is dropped in, or from the bow wave from a ship. These waves that move away from their source are known as swell. WebSoutheasterly 4 to 6, increasing 7 to severe gale 9. Sea State Moderate, becoming moderate or rough, occasionally very rough.
