Forecasters say El Niño is likely to develop by summer, with a chance of becoming very strong later in 2026
The Facts
- NOAA’s Climate Prediction Center says El Niño is likely to develop soon, with an 82% chance during the May-July period.
- Forecasters say there is a 96% chance El Niño will persist through the winter of 2026-27.
- Current conditions are still ENSO-neutral even as forecasters report warming signs in the equatorial Pacific that point toward a transition to El Niño.
- Multiple reports say forecast models indicate the event could become strong or very strong later in 2026, though its eventual intensity remains uncertain.
- El Niño is the warm phase of the ENSO climate pattern, marked by warmer-than-average sea-surface temperatures in the central and eastern equatorial Pacific.
- Forecasters and meteorologists say El Niño can alter weather patterns worldwide, including temperature, rainfall and storm activity, with effects varying by region.
- Several sources say possible impacts include drought in some places, heavier rain or flooding in others, and weaker Atlantic hurricane activity or fewer hurricanes in some U.S. regions.
- A key unresolved question is how strong this El Niño will become, because sources note that spring forecasts carry more uncertainty.
How left and right are reading this
- Both agree
- El Niño is likely to emerge soon and could persist into the winter of 2026-27, with the potential to disrupt weather patterns across regions even as its eventual strength remains uncertain because spring forecasts are less reliable.
- They split on
- Less a disagreement than a question of emphasis: the communities most exposed to drought, flooding, and other uneven regional disruption, versus the forecasting uncertainty that argues for measured planning before treating a strong event as certain.
Context
What is El Niño?
El Niño is the warm phase of the El Niño-Southern Oscillation, or ENSO, a recurring climate pattern tied to warmer-than-average waters in the central and eastern equatorial Pacific Ocean Spectrum News Bay N…,FOX 11 Los Angeles,Jamaica Gleaner.
What are forecasters predicting right now?
NOAA’s Climate Prediction Center says El Niño is likely to emerge by summer, assigning an 82% chance for the May-July period and a 96% chance that it lasts through the 2026-27 winter USA Today,WKMG,Santa Rosa Press De…. Some models suggest it could become strong or very strong later in the year, but forecasters say that outcome is not certain yet USA Today,livescience.com,FOX 11 Los Angeles.
Why does this matter beyond the Pacific Ocean?
Because El Niño can shift global weather patterns, it can affect rainfall, heat and storms far from the Pacific, raising the risk of drought in some regions and heavier rain or flooding in others; some U.S. forecasts also associate El Niño with fewer or weaker Atlantic hurricanes Newsday,Santa Rosa Press De…,Jamaica Gleaner,WKMG.
