Known as one of the greatest military secrets of “Operation Overlord,” the cross- English Channel invasion of the northern coast of France on June 6, 1944, called for the Allies with accurate wave and tidal forecast for landing operation. Times of small wave and low tide were essential for successful landing. We are revisiting forecasts (hindcast simulation) via modern day updated numerical modeling based on coupled tide-wave-storm surge physics. The wind conditions are reproduced by using the meteorological conditions from ECMWF ERA-20C data of assimilation group. An integrally coupled tide-surge-wave model based on the identical, homogeneous and unstructured meshes were used for correct resolving the physics of tide-wave-surge interaction and performing for each transect, perpendicular to the beach, respectively. The model domain covers the wide Northwest European continental shelf and fine meshes with about 20m resolution in the Normandy invasion beaches. We performed the real time tidal simulation and compared with Kelvin (Doodson-Lege) tidal prediction. The tidal and wave prediction time sequential results are posted in the website,, near the landing time, 6th of June 6:30 AM.
