Fig. 3

Time evolution of directional wave spectra on 4 June 2023 (columns 1–2) and 25 June 2023 (columns 3-4). Columns 1 and 3 show Spotter buoy observations, while columns 2 and 4 display the corresponding ResourceCODE hindcast estimates. Rows represent the temporal progression of the spectral distribution. Colours indicate wave energy density normalised by the maximum value at each time step, and black arrows denote wind direction, with their length scaled to wind speed.
