Recent model consensus from NOAA, WMO, and multi-model ensembles has driven the 65.5% implied probability for a peak RONI exceeding 2.5°C, reflecting the event’s rapid intensification amid record equatorial Pacific sea surface temperature anomalies. A downwelling Kelvin wave has deepened the thermocline and boosted eastern Pacific warmth, while strong ocean-atmosphere coupling sustains westerly wind anomalies and suppressed convection over Indonesia. RONI’s adjustment subtracting the tropical-mean SST anomaly isolates the ENSO signal from background warming, placing current JJA values near +1.4°C yet projecting a November–January peak that models indicate will surpass post-1950 records with roughly 70% likelihood. Traders are monitoring the next CPC diagnostic discussion and updated NMME runs for confirmation of these thresholds before the October–December resolution window.

The peak RONI is the single highest Regional Ocean 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.
