Trader consensus on peak RONI for the 2026–27 El Niño shows closely matched probabilities across moderate-to-strong ranges, reflecting genuine forecast uncertainty rather than consensus on intensity. Current equatorial Pacific sea surface temperatures remain near neutral, with models from NOAA and others diverging on the strength and timing of warming in key Niño regions that define RONI thresholds. Factors such as trade wind strength, subsurface heat content, and the potential development of downwelling Kelvin waves could tip outcomes toward higher values above 2.5, while persistent easterlies or weaker coupling might limit peaks to the 1.5–2.25 range. Historical ENSO cycles and early seasonal indices underscore how rapidly these conditions can evolve ahead of the typical boreal winter maximum.
