The World Meteorological Organisation has flagged an exceptional El Nino event, predicting significant climate disruptions and varied weather patterns across Europe and globally, with impacts expected to last into 2027.
‘No time to lose’ – World Meteorological Organisation mobilises with climate impacts expected well into 2027 Dublin's Dart line was flooded during storms earlier this year.

It said there was unprecedented consensus among national meteorological agencies about its strength and the duration of its impacts. Moving to Ireland?
The financial realities Americans need to consider Rainfall forecasts are much more varied, with drier-than-normal conditions and drought expected in some regions and significantly wetter weather and floods in others. , and comes as many parts of Europe, including Ireland, have yet to recover from the summer heatwaves and prolonged drought. El Niño is a natural climate phenomenon that occurs every two to seven years, driven by a build-up of heat in the waters of the equatorial eastern Pacific Ocean.
Sea surface temperatures were almost 3 degrees above normal in the region last month, but subsurface temperatures were more than 8 degrees above average in some places. The extra heat is dispersed widely by air and sea currents, and it upsets normal climate patterns, particularly in areas accustomed to large seasonal events such as monsoon season, hurricane season or dry season.
Impacts in Europe over the next three months are predicted to vary between northern and southern countries, with a particularly high probability of above-normal temperatures in the south, which will also be much wetter than normal. Northern Europe is expected to be slightly warmer than normal and also drier, but Ireland does not fall neatly into either region.
Those interactions can begin as remotely as the Indian Ocean, with El Niño causing a positive “dipole” that pulls warm water away from Indonesia and towards the Atlantic. That, in turn, feeds the waters that travel from the southern United States towards Ireland, the extra warmth bringing warmer, wetter conditions.
“We would normally expect to see a cooler-than-normal late winter, from January on, but because this is an unprecedented El Niño, we don’t have the same certainty. After the summer drought, many parts of Ireland would welcome consistent rainfall in the coming months, but persistent rain would prompt fears of a repeat of last winter’s flooding in the east and southeast of the country.
Almost every other part of the world can expect disruption, with the WMO warning: “El Niño is firmly established and will intensify into a very strong event in the coming months, with big impacts on rainfall and temperature patterns and associated risks of floods, drought and extreme heat. ” WMO secretary general Celeste Saulo said efforts were under way to get as much accurate information as possible and provide early warnings to the most vulnerable regions.
“Never before in the 50-year history of the World Meteorological Organisation have we launched such a major mobilisation,” she said. “We have no time to lose. ” United Nations secretary general António Guterres said the combined effects of El Niño and climate change were placing the planet in an unprecedented “danger zone”.
“El Niño is being supersized before our eyes. The science leaves no room for doubt: the planet is in uncharted waters,” he said. Christy Moore takes €660,000 dividend from his businessIrish teenager killed in Iceland crash named as 18-year-old from GreystonesKingspan green bond raises €850m
