El Niño is forecast to strengthen to very strong intensity during late 2026, with the World Meteorological Organization (WMO) indicating an exceptionally high likelihood of nearly 100% that El Niño conditions will persist through February 2027. NOAA’s Climate Prediction Center (CPC) separately gives a greater than 90% chance of a very strong event during Northern Hemisphere fall and winter 2026–27. A very strong El Niño increases the likelihood of major shifts in rainfall and temperature patterns across many regions, although the severity of impacts varies by location and season.
El Niño is firmly established in the central-eastern equatorial Pacific and is forecast to strengthen to very strong intensity before peaking toward the end of 2026, the World Meteorological Organization (WMO) said on September 3.
Forecasts from WMO Global Producing Centers indicate a nearly 100% probability that El Niño will persist through December 2026–February 2027, increasing the likelihood of major changes in rainfall and temperature patterns across many regions.
Sea surface temperatures across the central-eastern equatorial Pacific have risen sharply. WMO reported that the Niño 3.4 anomaly averaged approximately +1.5°C (+2.7°F) during May-July 2026 and reached +2°C (+3.6°F) in July.
