Here’s a concise update on the 2026 El Niño intensity forecast based on the latest publicly available summaries.
- What’s likely: Most forecasts in early 2026 point toward El Niño emerging later in the year, with probabilities rising through spring and into summer. The consensus from major climate centers indicates a transition from La Niña to El Niño is plausible around mid-2026, with increasing confidence into late 2026.[1][5][6]
- Intensity range: Forecasters estimate a spectrum from moderate to strong intensity is possible by late 2026, though there is substantial uncertainty—especially due to the spring predictability barrier that tempers confidence in exact strength.[2][5][1]
- Potential regional impacts: If El Niño reaches moderate to strong levels, expect shifts in global weather patterns such as warmer global temperatures, wetter conditions in parts of the southern United States and central Pacific regions, and drier or hotter conditions in others, with notable implications for hurricane activity and seasonal rainfall in affected zones.[7][8][1]
- Important caveat: None of the sources declare a confirmed “Super El Niño” yet; forecasts emphasize probability and range rather than a definitive categorization until observations strengthen later in 2026.[8][1]
Illustration: An illustrative scenario shows ENSO shifting from neutral toward El Niño by summer 2026, with the ENSO Index (Niño 3.4 region) gradually rising and potentially surpassing +1.5°C by late 2026, which would align with stronger ENSO impacts.[1][2]
If you’d like, I can pull the latest official forecasts (NOAA CPC, IRI, WMO) and summarize their current probabilities and expected timelines in a short chart or bullet list for quick reference. I can also tailor regional outlooks (U.S., Brazil, Europe) based on your interest.

The El Niño climate phenomenon is expected to form again in 2026 and may have significant impacts on the Brazilian climate, with predictions of prolonged heat waves, irregular rainfall, and an increase in severe storms in the South of the country. This information comes from Climatempo, which warns of a scenario similar to that recorded in 2023, when the event contributed to record temperatures and intense instability in various regions. Meteorological analyses indicate that the first signs of...
