The World Meteorological Organization (WMO) is forecasting a likely El Niño event in the Northern Hemisphere summer. The WMO indicates there is an 80% chance that El Niño conditions develop during June–August 2026. The organization also states there is a 90% chance that those El Niño conditions persist beyond that period, continuing at least until November 2026.
El Niño is an unusual climate pattern in the equatorial Pacific that can influence weather and temperature patterns globally, though the specific impacts can vary by region. The reported probabilities reflect the WMO’s assessment based on current observations and climate model guidance.
Both sources emphasize the same core figures from the WMO: an 80% likelihood of El Niño forming in June–August 2026 and a 90% chance of continuation through at least November. No additional details about specific regional outcomes are provided in the supplied text.
