Super El Niño 2026 Predicted with Near Certainty
5/13/2026, 11:08:42 PM
Core Event: Near-Certain Super El Niño Forecast for Late 2026
ECMWF’s forecasts rose from a 22 % chance in March 2026 to 100 % by May, indicating central Pacific sea-surface temperatures > 3 °C above average and a super-El Niño peak in November. NOAA’s Climate Prediction Centre assigns a 62 % chance of El Niño emergence June-August, persisting through year-end.
Background & Context: Historic Super El Niños
The 1877-78 super-El Niño caused drought, famine and > 50 million deaths across India, China and Brazil. Later super events in 1982-83 and 1997-98 produced trillion-dollar losses, while the 2023-24 El Niño set new global temperature records.
Key Figures & Institutions
Bill McGuire (UCL), Jeff Berardelli (WFLA-TV), Daniel Swain (California Institute of Water Resources), Deepti Singh (Washington State University), Fredi Otto (Imperial College London), Jemilah Mahmood (Sunway Centre for Planetary Health). Agencies: ECMWF, NOAA CPC, WMO, UK Met Office, World Weather Attribution.
Data, Statistics and Timeline
Probability rose 22 % (March) -> 80 % (April) -> 100 % (May) (ECMWF); NOAA gives 62 % for June-August emergence. Projected SST anomaly > 3 °C (super-threshold > 2 °C). Potential permafrost thaw of 1 million km² and 1-3 ft sea-level rise by century’s end. Timeline: November 2026 peak, global temperature maximum may lag into 2027.
Why It Matters: Global Weather Risks
Pacific-rim nations (Australia, Indonesia, Peru, Ecuador, Philippines) face drought, flooding and monsoon disruption. Teleconnections could bring colder UK winters and altered Atlantic storms. The warmed baseline amplifies heatwaves, drought, flood severity, food-security stress, permafrost melt and sea-level rise.
Official Statements & Responses
ECMWF issued a definitive super-El Niño outlook, citing unprecedented Kelvin-wave activity. NOAA expects El Niño conditions to persist through year-end. WMO highlighted rapid SST rise. UK Met Office warned of an “extremely powerful” El Niño. World Weather Attribution stressed that human-induced warming now magnifies El Niño-driven extremes.
Criticism & Opposition
Spring forecasts of El Niño strength have higher error margins, and regional impact models remain limited, especially for compound heat-drought-flood scenarios.
Conflicting Reports & Gaps
Probability estimates differ: ECMWF reports 100 % chance, NOAA 62 % for June-August emergence. The global temperature peak may occur in 2026 or lag to 2027, reflecting uncertainty in timing.

What’s Next: Monitoring and Preparedness
Researchers will watch whether the projected El Niño develops strongly enough in the coming months.
