Abstract
A sea state is typically composed of either wind-sea, swell-sea, or a combination of the two. Wind-seas are generated by local winds, while swell-seas generally have been generated in a distant storm and dispersed out of the generating area. A combination of sea and swell can produce bimodal sea conditions.
Data from Datawell directional Waverider buoys deployed by the National Network of Regional Coastal Monitoring Programmes of England, plus data from 3 industry buoys kindly provided by RWE Innogy and Wave Hub Limited, together provide an opportunity to assess the extent of bimodal seas both spatially and temporally.
The monthly percentage of occurrence of bimodal sea conditions are given in the following spreadsheet, together with summary statistics for monthly, seasonal and annual occurrence. This document will be updated annually.
The method for deriving statistics for bimodal seas and an assessment of their occurrence around the English coastline are described in:
