NOAA Sees 96% Odds El Niño Lasts Through Winter 2026-27
16 articles · Updated · The Inertia · May 14
A 96% probability now points to El Niño persisting through the 2026-27 winter, even though the Pacific has not yet officially shifted out of ENSO-neutral conditions.
NOAA’s Climate Prediction Center says the transition is likely soon, assigning an 82% chance that El Niño develops between now and July.
Forecasters cautioned that duration does not guarantee extreme impacts: no peak-strength category carries more than a 37% chance, leaving “Super El Niño” far from certain.
That uncertainty matters because El Niño can reshape weather worldwide, often bringing stormier conditions to the U.S. West Coast and warmer, drier weather to Australia.
The last super El Niño cost trillions; can our strained global economy withstand the coming humanitarian and financial shocks?
Will this super El Niño push global temperatures past the critical 2.0°C warming threshold for the first time?
As El Niño meets a record-warm planet, are our climate models truly prepared for the unprecedented extremes ahead?
The Imminent 2026 "Super" El Niño: Forecasting, Impacts, and How the World Must Respond
Overview
As of May 2026, while specific details about the probability and strength of the anticipated 'Super' El Niño are not yet available, major climate monitoring services are actively improving their forecasting capabilities. Copernicus, for example, is developing new features for its seasonal forecasts, such as near-surface wind speed predictions and advanced indices, to better capture the complex ocean-atmosphere interactions that drive El Niño events. These enhancements, driven by user needs and the demand for more accurate forecasts, aim to provide deeper insights into El Niño dynamics and help the global community prepare for potential impacts.
