Normandy landing time and place weather conditions

On the day of landing, the weather was extremely bad. Before landing, the allied forces lost the 10 landing craft and more than 300 officers and men due to the excessive wind and waves. Most of the officers and men on the landing craft are seasick and cold, and they are basically exhausted before they reach the battle site. After the landing operation began, it was also very difficult. Of the 32 amphibious tanks prepared in the west of the beach, 27 sank just after entering the sea because of excessive wind and waves, and two of the five surviving tanks were quickly destroyed by German artillery fire. Due to the tidal influence and disorder, many American soldiers who landed could not tell the direction and assembly point, and a large number of soldiers crowded on the beach waiting for the attack of German artillery. For two hours, not a single American soldier rushed to the western beach, only occupying a 9-meter-wide area of the eastern beach. The landing operation was almost a complete failure.
