Record-Breaking “Super” El Niño Emerges as Strongest on Record
By Drooid · · How we work
Core Event: Unprecedented Sea-Surface Temperatures
Scientists monitoring the central-eastern Pacific recorded daily sea-surface temperatures 3.05 °C above average on 19 September, surpassing the previous record of 3.02 °C set during the very strong 2015 El Niño. The anomaly is now described by the National Oceanic and Atmospheric Administration (NOAA) as the strongest El Niño observed since systematic records began in 1950. NOAA officially declared an El Niño on 11 June after satellite data showed sustained above-average Pacific temperatures for several consecutive months in 2026.
Background & Context
El Niño is a naturally occurring climate pattern that arises when warm water accumulates in the central and eastern equatorial Pacific, reversing the usual westward trade-wind flow. The resulting heat release into the atmosphere reshapes the jet stream, which in turn steers weather systems worldwide. While each El Niño event is unique, scientists note a trend toward more extreme episodes since the mid-20th century, though a direct causal link to anthropogenic climate change remains unconfirmed.
Data & Statistics
- Sea-surface temperature anomaly on 19 September: +3.05 °C (record high).
- NOAA’s June 11 declaration based on multi-month satellite temperature averages above normal.
- Historical comparison: previous record of +3.02 °C during the 2015 event.
- Typical Atlantic hurricane season averages seven hurricanes; the current year has produced zero so far, according to the National Hurricane Center.
Projected Global Impacts
The Met Office warns that the El Niño will influence weather across the globe throughout autumn and winter, contributing to a “far-reaching” pattern of anomalies. In the United States, the National Weather Service anticipates:
- Poor skiing conditions in the East Coast and Appalachian Mountains.
- Potential record snowfall in the southern Rockies.
- Increased winter thunderstorms and beach erosion in Florida.
- Heavy rains and heightened flood risk in southern California.
In Europe, the United Kingdom’s Met Office projects a wetter winter with flood potential for London and western regions. In the Southern Hemisphere, NOAA forecasts severe drought in Indonesia and record heatwaves in Peru, raising wildfire risk. The altered jet stream also appears to be disrupting Atlantic tropical storms before they can develop into hurricanes, contributing to the current zero-hurricane count.
Official Statements & Responses
- The Met Office issued an El Niño warning, labeling the developing event an “unprecedented” phenomenon that could make 2027 the hottest year on record, surpassing the 2024 benchmark.
- The National Weather Service highlighted the mixed regional effects, noting both potential snow deficits and excesses depending on geography.
- The National Hurricane Center reported the absence of hurricanes to date, attributing the lull in part to wind shear generated by the El Niño-driven jet-stream changes.

What’s Next
NOAA and the Met Office plan to issue periodic updates as the El Niño peaks later in the year. Forecasts suggest the strongest atmospheric impacts will occur during the Northern Hemisphere winter months, with continued monitoring of jet-stream shifts, precipitation extremes, and tropical cyclone activity. Stakeholders in agriculture, water management, and disaster preparedness are advised to incorporate the evolving forecasts into seasonal planning.
