D-Day: The Irish postmistress’s weather report that helped Allied forces avert disaster
“Please check, please repeat.” A frantic telephone call from a woman with a cut-glass English accent took Maureen Sweeney by surprise.
A short time earlier, the Irish postmistress had filed her hourly weather report: “Force six wind and a rapidly falling barometer.”
It was her 21st birthday but she and her soon-to-be husband Ted, keepers of the Blacksod Lighthouse, had their job to do.
Their son Vincent recalls: “My mother said, ‘oh my God, were my readings wrong?'” They were not wrong, but they had caused alarm for those planning the imminent D-Day landings.
Some 5,000 ships and 11,000 aircraft had transported 156,000 Allied troops in readiness for the beachfront offensive at Normandy.
It was Maureen’s 21st birthday when she sent the weather report on 3 June

But there was one thing UK, US and Canadian commanders had no control over – the weather on 5 June, the date they had earmarked for invasion.
It is small and unremarkable in appearance, but the lighthouse at Blacksod Point in County Mayo was about to claim its place in history.

Ted and Maureen Sweeney played a critical role in the success of the D-Day landings
Situated on the western edge of Europe, flanked by a pretty fishing village, immaculate beaches and the neighbouring Achill Island, it surveys the vast Atlantic Ocean.
Vincent, who is the current lighthouse attendant, explains: “We have the first gaze into the Atlantic.
Maureen’s report persuaded officials to postpone the landings by a day
“Any weather that is coming in will come in over us.
“But this depression, with northwest winds, was coming in directly over Blacksod, down through the UK and into the Channel.
“That would have hit Normandy in about five hours, so it was critical.”
Despite Ireland’s neutrality during the Second World War, it continued to supply weather forecasts to Britain under an agreement in place since independence.
Maureen never imagined for a moment that the fate of tens of thousands of Allied troops hung on her readings.

Her report on 3 June indicated a cold front lying halfway across Ireland and moving rapidly south-eastwards, towards Normandy.
Had the plan gone ahead, Allied troops would have faced catastrophe, trying to steer boats through rough water and scramble on to the beach in driving rain.
Maureen’s weather warning, checked and double-checked by Ted, persuaded those in charge to postpone by a day.
In the early hours of 5 June, at General Eisenhower’s morning briefing, another report from Blacksod confirmed that the cold front had passed.
A loud cheer went up in the room, the long-awaited weather clearance had arrived and he gave the order for Operation Overlord to proceed.
Maureen’s efforts were recognised with a medal by the US House of Representatives
Shortly before her death last year aged 100, Maureen recalled those three days in June 1944.
“Eisenhower was making up his mind… but when he saw the report from Blacksod, it confirmed that he was right, and he went ahead then,” she said.
It was more than a decade after D-Day, when weather forecasting arrangements changed, before Maureen and Ted learned the critical role they had played.
Vincent explained: “They had a fair idea that there might be something up because the weather went in every hour on the hour and then came the call to please check, please repeat.
“But it was 1956, when the weather station moved from Blacksod, when an official came to assist with the relocation.
Maureen discovered how key she had been to D-Day more than a decade later
“He said, ‘by the way Ted and Maureen, do you realise the significance of the weather forecasts you sent on the 3, 4 and 5 June 1944?’
“‘I can tell you now that those forecasts were the decisive factor before Operation Overlord could proceed’.”
Observations were taken at various locations by Royal Air Force, Royal Navy and United States Army and Air Force meteorologists.
But the forecast from the Irish Meteorological Service, based on readings from Blacksod on Mayo’s Mullet Peninsula, proved crucial.
A certificate praising Maureen’s efforts
Had Maureen not accurately read the signs, the D-Day campaign, the turning point of the Second World War, would almost certainly have ended in failure.
The US House of Representatives acknowledged her contribution with a medal and certificate recognising her “laudable actions” for perpetuity.
Her grandson Fergus Sweeney, a tour guide at the lighthouse, says his grandmother saved the most ambitious invasion in history from disaster.
“It would certainly be a different world today. You can imagine what would have happened to the allies had they gone during the bad weather.
Fergus believes it ‘would certainly be a different world today’ without Blacksod
“The invasion would have been a disaster… but of course, that would have changed the world we live in.
“The world we live in today is dictated by what happened at the end of the Second World War and so everything that we know now would be vastly different,” he said.

Blacksod Lighthouse remains a vital landmark for passing seafarers and is now a refuelling station for search and rescue helicopters.
The keepers of the light here are still saving lives 80 years on.
All flights were halted at Edinburgh Airport this morning due to an IT issue affecting its air traffic control provider.
In a post on X, formerly Twitter, the airport later announced service had resumed.
Its post read: “Flights have now resumed following the IT issue with our air traffic provider.
“We thank passengers for their patience and understanding.”
But passengers continue to feel the effects.
A Delta Air Lines flight from New York to Edinburgh was diverted to Dublin after going into a holding pattern over the Scottish capital.
And a live arrivals board on the airport’s website showed multiple flights diverted, delayed and cancelled.

Morven McCall and Cody Stevenson, both 19, were due to fly easyJet from Edinburgh to Amsterdam on their first trip away together.
Morven told Sky News: “We literally just got into the airport and as soon as we walked through the door there was an announcement that it had been cancelled.
“I was ill over the summer and had to cancel two holidays already, this was our first time going away together. We are just gutted and stressed.”

One passenger was on a plane when they found out.
They said: “We boarded our flight and pushed back on time for an 8.45 (am) departure, then sat for a while before the pilot told us what was happening.
“He updated us a couple of times, cabin crew are brilliant at handing out water etc, and I’m surprised that everyone appears to be upbeat. But then you do wonder how long for, just been told we’re hoping to be in the air in 20 minutes.”
Another passenger told us: “The first news was from the airport announcement as we were halfway through boarding, saying the airfield was closed due to air traffic control down.
“No one knew what was going on. We’d already been delayed a bit before boarding, with no reason. I suspect problems started about 9am.”
It comes after an earlier announcement that all flights had been halted.
“No flights are currently operating from Edinburgh Airport,” the previous statement said.
“Teams are working on the issue and will resolve as soon as possible.”
There was no timeframe for recovery initially, Sky News learned.
It’s understood by PA that the issue was not linked to today’s Cloudflare outage.
Edinburgh Trams also posted on X, writing: “If you’re travelling with us to @EDI_Airport this morning, please be aware that flights are not currently operating.”
The airport urged passengers to contact their airline for the latest information on flights.
An average of 43,000 passengers per day use the airport, which is served by 37 airlines flying to 155 destinations.

“Our prosecutors have worked at length to support a detailed and complex investigation by Staffordshire Police, carefully reviewing the available evidence to establish that there is sufficient evidence to bring the case to trial and that it is in the public interest to pursue criminal proceedings.”
