Weather played a critical role in the decision of when to invade Normandy Beach in northern France. Each element of the allied forces needed a certain type of phenomena that best suited their needs. The navy and army needed high tides so the invading soldiers would not get hung up in the water. Further inland, the paratroopers needed a moonless sky so they would not be seen. Dates in May and very early June were set which met those criteria, but were called off because of very bad weather. On the early morning on this date, the weather was once again atrocious with high winds and rain. It was either invade now, or wait until late June when all the elements of moon and tide were together again. But this would risk the Germans fortifying their positions at Normandy. So the decision was made to attack on June 6th. The waves were high, and many soldiers got sea- sick, but the mission was a success. As a matter of fact, the weather was even worse in late June for the alternate landing than it was on this date.
