Recent observations confirm El Niño conditions are firmly established and intensifying across the equatorial Pacific, with Niño 3.4 sea surface temperature anomalies already reaching 1.8°C or higher. NOAA’s Climate Prediction Center and the World Meteorological Organization report greater than 90% probability of a very strong event—typically defined as Niño 3.4 peaks at or above +2.0°C—during October–December 2026 and through meteorological winter, with near-100% likelihood of persistence into early 2027. Multi-model ensembles show exceptional agreement on record or near-record strength, driven by high oceanic heat content and westerly wind anomalies. While model spreads allow for modestly lower peaks, realistic scenarios challenging super El Niño status would require unexpected rapid weakening not supported by current dynamical forecasts or historical analogs.

A Super El Niño is an El Niño event in which RONI reaches this threshold for at least one overlapping ENSO season. An ENSO season is one of NOAA's standard overlapping 3-month periods (e.g., ASO, SON, OND, NDJ, DJF).
This market may resolve "Yes" immediately upon NOAA's first publication of a qualifying RONI value for any listed season. If no season has qualified, this market will not resolve "No" until NOAA publishes the DJF 2026-27 value since DJF captures El Niño's typical peak-strength window and an earlier "No" could contradict the final published data.
The first published RONI value for each listed season is final and governs this market's resolution; no subsequent revision to any season's value will be considered or will change the outcome once that season's first value has been published.
