2026 Ultra-Strong El Niño Declared: Global Weather Stakes Rise

On 11 June 2026 NOAA declared that sea-surface temperatures in the central-eastern Pacific have been >= 0.5 °C above average for five months, meeting El Niño criteria. The agency gives a 63 % chance the event will become “very strong” (anomalies > 2 °C) by the November-January season, placing it among the largest since 1950.

El Niño is the warm phase of the ENSO cycle, recurring every 2-7 years. Recent decades have set global temperature records, with 2024 and 2025 among the warmest. Scientists such as Muhammad Azhar Ehsan and Abby Frazier note that a warming baseline can magnify El Niño extremes, though the WMO says no clear link to climate change.

NOAA assigns a 63 % chance of a very strong El Niño and a 30-40 % chance of a “super” event (sea-surface > 3.6 °F above average). ECMWF projects up to 3.5 °C above normal in the equatorial Pacific by December. Gottschalck cites soybean gains in 18 states; Ferrari warns mixed dairy outcomes.

The extra ocean heat is expected to raise global temperatures, intensify heat waves, and increase extreme rainfall, flooding and drought. In the U.S., higher temps could slow growth, per Marshall Burke, while grain yields may improve and livestock face stress. Regions from Hawaii to India face heightened risk.

NOAA’s advisory stresses monitoring and preparedness, noting unprecedented Pacific warmth. UN Secretary-General Guterres called the event “an urgent climate warning.” Ehsan urged preparedness over fear, while the WMO said El Niño impacts are amplified by existing warming but stopped short of attributing them to emissions.

The WMO and some analysts argue there is no direct evidence that anthropogenic warming strengthens El Niño, contrasting with scientists like Frazier and Ehsan who see a trend toward greater intensity.

Models differ on the likelihood of a “super” El Niño, ranging from 30-40 % to no official definition. Peak timing estimates vary, and economic and regional impacts remain uncertain.

NOAA will issue seasonal outlooks via its Climate Prediction Center; the WMO will coordinate global monitoring. Emergency managers and agricultural agencies are urged to factor flood, heat-wave and hurricane risks into 2026-27 plans.
