Weather Replay: How Meteorology Crucially Aided D-Day and Europe's Liberation in WWII

Weather was a weapon during World War II, so critical that forecasts were classified as military secrets to deny them to the enemy. As German forces advanced, weather reports ceased to be disseminated, according to Christophe Salamin of MétéoSuisse.

The Allies held a crucial weather advantage, largely due to their extensive observation network. This included ground stations, reconnaissance aircraft, weather balloons, and ships. Their coverage spanned much of the North Atlantic and the British Isles, a vital region as most European storms originate from the west.

This meteorological edge was particularly significant for the D-Day landings on June 6, 1944. The ability to accurately predict weather conditions was paramount for the success of the invasion, which ultimately played a pivotal role in the liberation of Europe from Nazi Germany.

When we go back in time, we observe that meteorological forecasts ceased to be disseminated as new territories were conquered by the German army.
