A potentially record-breaking El Niño is building in the Pacific, and the scale of this one has already earned it a rather dramatic nickname: “Godzilla.”
The World Meteorological Organization says the climate event is strengthening rapidly and is expected to peak around December, with El Niño likely to stick around into February 2027. Sea surface temperatures across the central and eastern tropical Pacific are heading towards levels not seen in the observational record.
So, what does a warming Pacific have to do with Britain? Quite a bit, potentially.
El Niño can influence weather patterns thousands of miles away, shifting rainfall, temperatures and atmospheric circulation across the globe. For the UK, the Met Office expects the current event to increase the likelihood of wetter, windier and more unsettled conditions through late autumn and early winter.
That does not mean a giant storm is about to sweep across Britain. Nor does it mean snow is guaranteed.
There has been plenty of speculation about deep freezes, heavy snow and a weakened polar vortex later in the winter, but those outcomes are far from certain. The polar vortex is just one piece of a much bigger atmospheric puzzle, and current forecasts cannot tell us exactly what the UK will experience months from now.
What we do know is that this is an unusually powerful global climate signal.
A strong El Niño can bring very different consequences depending on where you are, from heavier rainfall and flooding in some parts of the world to drought, heat and wildfire risk in others. Its effects can also ripple into food production, water supplies, energy demand and wider infrastructure.
For Britain, the immediate takeaway is less “prepare for the apocalypse” and more “keep an eye on the forecast.”
Because while the Pacific is warming thousands of miles away, the weather patterns it helps shape could eventually turn up on Britain’s doorstep.
