The dataset contains statistics for significant wave height (Hs), mean wave period (Tm), peak wave period (Tp) and mean wave direction (θm) for Hindcast (1979-2005) and a multi-model ensemble of 17 EURO-CORDEX GCM-RCMs projections for the following periods: Baseline (1979-2005), Mid-century (2034-2060) for RCP 8.5, and End-of-century (2074-2100) for RCP 8.5. The following statistics are included providing seasonal and monthly means: Significant wave height: For hindcast, raw GCM-RCMs and bias-adjusted GCM-RCMs - Average significant wave height - 10, 50, 90, 95 and 99th - Maximum significant wave height - Average Hs when Hs>90 and 95th percentiles of the hindcast - Number of sea states when Hs>90 and 95th percentiles of the hindcast - Percentage of sea states when Hs>90 and 95th percentiles of the hindcast - Average Hs when Hs>1.25, 2.5 and 4 m - Number of sea states when Hs>1.25, 2.5 and 4 m - Percentage of sea states when Hs>1.25, 2.5 and 4 m - Number of days with at least two consecutive days when daily-max Hs>90th and 95th percentiles of the hindcast - Percentage of days with at least two consecutive days when daily-max Hs>90th and 95th percentiles of the hindcast Mean wave period: For hindcast and raw GCM-RCMs - Average mean wave period - 10, 50, 90, 95 and 99th percentiles - Maximum mean wave period Peak wave period: For hindcast and raw GCM-RCMs - Average peak wave period - 10, 50, 90, 95 and 99th percentiles - Maximum peak wave period Mean wave direction: For hindcast and raw GCM-RCMs - Mean Circular mean - Circular standard deviation Time span: - Hindcast/Baseline: 1979-01-01 – 2005-12-31 - Mid-century: 2034-01-01 – 2060-12-31 - End-of-century: 2074-01-01 – 2100-12-31
