The tide, swell and current conditions have been analysed using reference data and by establishing specific models. The tides are semi-diurnal with important tidal ranges, reaching 13 m in rare cases (coefficient 120). The extreme swell and current conditions have been carefully analysed.
The entire study zone has been explored with a sounder, which has enabled us to estimate the area's bathymetry with great accuracy. With depths varying between 4 and 20 m and gentle slopes in most of the study zone, the bathymetry is favourable to an offshore wind farm.
