Recent NOAA Climate Prediction Center data show the 2026–27 El Niño rapidly intensifying, with weekly Niño 3.4 anomalies reaching +3.3 °C and the three-month RONI at +1.7 °C for July–September. Subsurface heat content remains exceptionally high across the eastern equatorial Pacific, sustaining further strengthening through year-end per multi-model consensus. The October 8 CPC outlook assigns an 83 % probability that the October–December RONI will exceed +2.5 °C—the threshold for a historic event surpassing all post-1950 episodes—while strong-to-very-strong conditions (> +1.5 °C) are expected to persist through January–March 2027 at over 83 % likelihood. These verified observations and forecast probabilities underpin trader consensus favoring a peak RONI above 2.5.
