Despite being a neutral country during the ear Ireland communicated daily weather information from the west coast of Ireland to the Met Service in Dunstable in the UK. In planning the D-Day landings the allies needed to ensure that the invasion was not impacted by inclement weather and took heed of the information coming from Blacksod in Co. Mayo in the west coast of Ireland (next stop America). The information provided by Ted Sweeney, the lighthouse keeper was suggesting that there was going to be a storm in the English Channel on the 5th June 1944, the original day planned for the landings. Allied leaders were reluctant to accept this forecast as southern England has been enjoying a heatwave in early June 1944. James Stagg a Scottish weather expert on the planning team was under immense pressure to ensure an accurate forecast as other leaders wanted to go ahead on the 5th June.
Stagg prevailed and as a result of the forecast from Blacksod, the landings were postponed by one day to the 6th June. There was indeed a storm in the English Channel on the 5th June1944. Luckily the postponement of the landings resulted in their success. The rest, as they say, is history.
