The UK’s Met Office has identified a developing El Niño event over the Pacific Ocean that is expected to be the strongest recorded in more than a century. According to the agency, Pacific sea temperatures are projected to rise by 3 degrees Celsius, significantly exceeding the typical 1 degree increase associated with standard El Niño patterns and even surpassing the 2 degree threshold considered a major event.
MetOrological forecasters expect this phenomenon to produce widespread global impacts, with particularly acute effects in tropical regions. South America and the western Pacific are anticipated to experience severe droughts, while southern Africa and northeastern Australia face elevated drought risk. In contrast, northwestern Europe, including the UK, is projected to encounter wetter and stormier conditions during the autumn months, with heightened rainfall and storminess expected around November.
The El Niño pattern is also forecast to drive increases in global average temperatures. Scientists predict that 2027 will likely become the warmest year on record, potentially surpassing 2024’s record temperatures and temporarily exceeding 1.5 degrees Celsius above preindustrial levels. This temperature elevation results from significantly greater heat transfer from the ocean to the atmosphere during large El Niño events.
The forecasted autumn and winter precipitation comes as the UK currently faces severe drought conditions following record heatwaves and minimal rainfall in recent months. England and Wales have entered drought status, with reservoir levels at 62.6 percent—substantially below normal for this period. However, officials cautioned that months of sustained rainfall would be required to fully replenish water systems, and current autumn forecasts suggest insufficient precipitation to restore normal conditions before December. In response to escalating extreme weather patterns, the National Drought Group elevated its coordinated response efforts, transitioning from monthly to weekly meetings to address increasingly volatile conditions driven by human-influenced climate change.
