NOAA’s latest ENSO Diagnostic Discussion reports El Niño is strengthening rapidly, with sea surface temperature anomalies already exceeding +2.0°C in key Niño regions and greater than 90% probability of a very strong event—typically defined as peaks above 2.0°C on the Niño 3.4 index—through Northern Hemisphere fall and winter 2026-27. Multiple dynamical models and ensemble forecasts show continued intensification driven by deepening subsurface warmth and persistent westerly wind anomalies, pushing many runs toward record or near-record strength by November–January. This official outlook and model consensus underpin the market’s 91.2% implied probability for a super El Niño. Remaining uncertainty centers on exact peak magnitude, with a roughly 69% chance cited for an event exceeding prior records; revised model runs or unexpected atmospheric shifts could still moderate the outcome ahead of peak season.
