Technical details
- Model: ECMWF SEAS5 (system 51) ensemble mean, from the Copernicus Climate Data Store.
- 2 m air temperature anomaly: +0.35°C, averaged over September to November 2026, relative to the model's 1993 to 2016 average.
- Taken at the model grid point nearest -19.00, 29.20, so it represents that area rather than the whole country.
- Chances (cooler / about usual / warmer): 29% / 30% / 41%. Estimated by Nino Tracker from the size of the anomaly, because the ensemble mean product does not include the model's own odds.
- Confidence is set by the anomaly's size: under 0.5°C low, 0.5 to 1°C moderate, 1°C or more high.
El Niño right now
Strong El Niño
El Niño is a natural warming of the central and eastern tropical Pacific Ocean that shifts weather patterns around the world. Over June to August 2026, sea temperatures there averaged about 1.8°C above normal, which counts as a strong event.
Technical details
- Oceanic Niño Index (ONI): +1.80 for JJA 2026. It is the 3-month average sea surface temperature anomaly in the Niño 3.4 region (5°N to 5°S, 120°W to 170°W), from NOAA.
- El Niño conditions are +0.5°C or more, La Niña −0.5°C or less, sustained for five overlapping 3-month seasons. Strength: weak 0.5 to 0.9, moderate 1.0 to 1.4, strong 1.5 to 1.9, very strong 2.0 or more.
- NOAA now uses a relative version of this index (RONI) for official monitoring. The ONI is still published each month.
