Britain Faces Winter of Extreme Weather Amid Super El Niño

Britain is bracing for a potentially chaotic winter season as scientists warn that a powerful Super El Niño phenomenon is likely to intensify storms and bring colder, more disruptive weather. This forecast comes after the UK was already battered by Storms Austen and Boelo in recent weeks, with a third system, Storm Chloe, being tracked.

Experts state that the current stormy conditions are consistent with what is expected during a strong El Niño year. However, with this event on track to be one of the most powerful recorded, its impact on British weather could be severe. Professor Ilan Kelman, a disaster and climate expert at University College London, explained that El Niño typically results in a warmer and stormier autumn, followed by a colder and stormier winter for the UK.

"What El Niño does, it increases the likelihood that we will get more storms, and that they will be more intense," Kelman told the Daily Mail. He noted that while an individual storm cannot be directly attributed to El Niño or climate change, the phenomenon influences global climate systems, including ocean temperatures, the jet stream, and the polar vortex. These changes can create conditions conducive to more severe weather events in Britain.

"Under El Niño, we typically get very intense and very frequent storms," Kelman said. "The temperature tends to be milder, but we do get these storms, so people simply need to be ready for it."

While recent storms brought wind gusts exceeding 70 mph, damaged buildings, and disrupted transport, Kelman cautioned that these might only be the beginning. "We should be ready for cold and for storms from January to March," he advised. "The expectation is with the colder El Niño… I think London should be ready for snow."

The recent storms caused fatalities due to falling trees and flooding, disrupted power to thousands of homes, and impacted major transport routes. Rivers overflowed in several areas, leading to flood warnings and evacuations.

Dave Throup, a flooding expert and former Environment Agency manager, commented that "Big El Niño years increase the chances of a storm autumn in the UK, and this year's a record breaker." Historian Peter Frankopan added that El Niño's effects can influence the Atlantic jet stream, leading to stronger winds, worse storms, and increased rainfall in the British Isles, particularly raising the risk of flooding in western Britain.

New figures from the World Meteorological Organisation (WMO) indicate that the current Super El Niño is of "unprecedented strength." Sea surface temperatures in the tropical Pacific have risen significantly above average, far exceeding the threshold typically used to declare an El Niño event. The WMO reported that this El Niño is expected to peak towards the end of 2026, with its impacts continuing beyond that.

Kelman emphasized the need for communities to be prepared for increasingly extreme weather, particularly vulnerable families. "Of course they're going to be in trouble when there's a storm," he said. "Of course they're going to have difficulties when there's snow."

A spokesperson for the Met Office noted that while El Niño can influence weather patterns, favouring a wetter and windier start to winter, it is one of several factors affecting the UK's weather. Therefore, it is not possible to directly attribute recent storms solely to El Niño.

El Niño is the warm phase of the El Niño-Southern Oscillation (ENSO), a recurring climate pattern across the tropical Pacific. Its phases, including the cool La Niña and neutral periods, can shift every two to seven years, influencing global temperature, winds, and precipitation. During an El Niño phase, the surface of the central and eastern tropical Pacific Ocean warms, leading to reduced rainfall over Indonesia and increased rainfall over the Pacific. Surface winds along the Equator weaken or reverse direction.
