Recent NOAA Climate Prediction Center data show the 2026 El Niño rapidly intensifying, with Niño 3.4 sea-surface temperature anomalies reaching +2.1°C in September and weekly values near +3.3°C, supported by deep subsurface heat content exceeding +10°C in the eastern Pacific. Model consensus projects a peak near +3.7°C around December, yielding an 83% chance the October–December Relative Oceanic Niño Index exceeds +2.5°C—the threshold for a historic event surpassing all prior episodes since 1950. This drives the 97.2% market-implied probability for a Super El Niño through winter 2026–27. Remaining uncertainty centers on exact peak timing and any late-season weakening, though subsurface conditions make sharp reversal unlikely before January–March.
