Maureen Sweeney, Weather Forecaster Behind D-Day Landings, Passes Away at 100

Maureen Sweeney, the legendary weather forecaster who played a pivotal role in changing the timing of the D-Day landings during World War II, has died at the age of 100. The news of her passing was confirmed by RTÉ News on December 17, 2023.

Born in 1923, Sweeney grew up with a keen interest in meteorology, a field dominated by men at the time. Despite the challenges she faced, Sweeney persevered and became one of the first female weather forecasters in history. Her groundbreaking work would later make a significant impact on the outcome of one of the most critical military operations of the 20th century.

In the months leading up to the D-Day landings in June 1944, Sweeney was stationed at the Met Office in London, where she meticulously analyzed weather patterns over the English Channel. Her expertise in interpreting weather data and her ability to accurately predict future conditions made her an invaluable asset to the Allied forces planning the invasion.

It was Sweeney’s forecast on June 5, 1944, that ultimately influenced the decision to delay the D-Day landings by one day. Her analysis indicated that the original date of June 5 would be met with severe weather conditions, including heavy rain and strong winds. This crucial information prompted General Dwight D. Eisenhower, the Supreme Allied Commander, to postpone the operation to June 6, a day that proved to have more favorable weather conditions.

The significance of Sweeney’s contribution cannot be overstated. Her accurate forecast allowed for better strategic planning, ultimately increasing the chances of success for the Allied forces and changing the course of World War II. Her dedication and expertise in meteorology played a critical role in saving countless lives and shaping the outcome of one of history’s most pivotal moments.

Throughout her career, Sweeney continued to make significant contributions to the field of meteorology. She pioneered new techniques and methodologies, revolutionizing weather forecasting and paving the way for future advancements in the field. Her groundbreaking work inspired a new generation of meteorologists, particularly women, to pursue careers in this male-dominated industry.

Despite her achievements, Sweeney remained humble and modest throughout her life. She rarely sought recognition for her contributions, preferring to let her work speak for itself. However, her impact on weather forecasting and her instrumental role in the success of the D-Day landings have solidified her status as a true trailblazer and a hero.

While the cause of Sweeney’s death has not been disclosed, her legacy will live on in the annals of history. Her groundbreaking work and her unwavering dedication to her craft have left an indelible mark on the field of meteorology and the world at large. Maureen Sweeney will forever be remembered as a pioneer, a hero, and a visionary who changed the course of history through her expertise and determination..
