2025 El Nino Or La Nina John S Stephens. 2-year history of sea surface temperatures in the Niño-3.4 region of the tropical Pacific for all La Nina events since 1950 (gray lines) and the recent (2024-25) event (purple line). Average sea surface temperatures in the Niño-3.4 region of the equatorial Pacific Ocean were at least 0.5°C (0.9°F) warmer than average (5°N-5°S, 120°W-170°W) in the preceding month, and the anomaly has persisted or is expected to persist for 5 consecutive, overlapping 3-month periods (e.g., DJF, JFM, FMA, etc), and the atmosphere over the tropical Pacific exhibits.
2025 El Nino Or La Nina John S Stephens. Sustained positive values are indicative of La Niña conditions, and sustained negative values indicative of El Niño conditions La Niña: characterized by a negative ONI less than or equal to -0.5ºC
