Recent rapid intensification of the 2026 El Niño, with weekly Niño 3.4 sea surface temperature anomalies reaching +3.0°C in mid-September, underpins the 77.5% market-implied probability for a peak RONI exceeding 2.5°C. NOAA’s Relative Oceanic Niño Index (RONI) adjusts Niño 3.4 values by subtracting broader tropical ocean anomalies to isolate ENSO signals from long-term warming. The June–August RONI stood at +1.4°C, yet all 22 forecast models project a very strong event (≥+2.0°C) through winter 2026–27, with 75% odds of a historic October–December peak surpassing the 1982–83 record on the three-month RONI. Subsurface heat content and sustained atmospheric coupling support further strengthening ahead of the typical November–January maximum, though model spread and potential late-season adjustments introduce remaining uncertainty around exact peak timing and magnitude.

This market resolves "Yes" if the peak RONI for the 2026–27 El Niño is below +1.5°C. Otherwise, it resolves "No".
The peak RONI is the single highest Relative Oceanic Niño Index (RONI) value reported by NOAA's Climate Prediction Center (CPC) across the overlapping three-month seasons ASO 2026, SON 2026, OND 2026, NDJ 2026-27, and DJF 2026-27, as reported in official NOAA CPC RONI updates (https://www.cpc.ncep.noaa.gov/products/analysis_monitoring/enso/roni/).
The first published RONI value for each listed season is final and governs resolution; no subsequent revision to a season's value will change the outcome once that season's first value has been published. If CPC's RONI dataset is permanently discontinued, other information from NOAA may be used.This market resolves "Yes" if the peak RONI for the 2026–27 El Niño is at least +1.5°C and below +2.0°C.
