Coastal storm surges and wave heights are validated with available observations (tide gauges, waves buoys and satellites). The numerical simulation covers the period 1950-2021 with high temporal sampling (1h) and at unprecedented spatial resolution for a basin scale analysis, that reaches 200 m along the coastlines. This study investigates the spatial and temporal variability of coastal extreme sea levels in the Mediterranean basin, using a new ocean hindcast generated with a coupled hydrodynamic-wave model that simulates storm surges and wind-waves. In addition, wind-waves generated by the same atmospheric perturbations may also contribute to coastal extremes through wave setup (temporal rise above the mean sea level due to dissipation and breaking of waves in shallow waters close to the shore). In the Mediterranean Sea, coastal extreme sea levels are mainly caused by storm surges driven by atmospheric pressure and surface winds from extratropical cyclones. 2Department of Physics, University of the Balearic Islands, Palma, Spain.1Department of Marine Technologies, Operational and Coastal Oceanography (TMOOC), Mediterranean Institute for Advanced Studies, University of the Balearic Islands - Consejo Superior de Investigaciones Científicas (UIB-CSIC), Esporles, Spain.Tim Toomey 1*, Angel Amores 1, Marta Marcos 1,2 and Alejandro Orfila 1
