- The planning team responsible for the invasion of Normandy had to consider the weather, the moon, and tides when assigning a date for D-Day. Air operations required clear skies and a full moon for good visibility, while naval operations needed low winds and calm seas to safely transport troops ashore. Ground troops needed to land at low tide, when German beach obstacles were exposed and easier to deal with.

- General Eisenhower needed a full moon, a low tide, little cloud cover, light winds, and low seas for the invasion to proceed. Weather observations taken in western Ireland on 3 June alerted the Allies to an approaching storm, leading to a delay in the invasion.

- The weather forecast was critical for the success of D-Day. The invasion required specific conditions including low tide with calm seas and 3 miles (5 km) visibility. The Allied forecasters had advantages over the Germans due to better observation of weather moving in from the ocean and cracking the German code used to encrypt communications.
