July model runs from 667 ensemble members across 14 forecast systems now point to a 2026-27 El Niño peaking near 3.6°C above average, roughly 1°C above the strongest event in records dating to 1877.
That outlook strengthened as models converged and observed Pacific conditions developed at record speed, raising the chance that human-driven warming pushes global temperatures to new highs in 2027, or even later this year.
Using NOAA’s newer Relative Oceanic Niño Index, which adjusts for a warmer tropical baseline, the event is still given about a 77% chance of becoming the strongest El Niño on record.
Early impacts are already visible: India’s monsoon rainfall was about 20% below average through July 13, the Atlantic had logged just one named storm, and four systems were being tracked in the eastern and central Pacific.
Forecasters still caution that a record El Niño may not produce textbook regional effects, because background ocean warming and a long-running cool trend in the eastern tropical Pacific can mute or reshape teleconnections.
A Pacific cooling trend is battling a super El Niño. Which will dictate our weather?
Why did scientists change how they measure El Niño just as the strongest one on record hits?
The 2026–27 Super El Niño: Record-Breaking Climate Threats and Global Response in a Warming World
Overview
As of mid-2026, El Niño conditions are firmly established in the tropical Pacific and are expected to intensify rapidly in the coming months. Leading agencies like NOAA and WMO confirm these developments, and advanced seasonal forecasts from models such as ECMWF’s SEAS5 and the C3S multi-system ensemble support projections of a strong El Niño. This has sparked widespread discussion about the potential for significant global climate impacts later in 2026. The early signals from these models have drawn considerable attention, raising expectations and highlighting the importance of monitoring and preparedness as the situation evolves.
