The U.S. National Oceanic and Atmospheric Administration (NOAA) and climatologists said that the 2026 El Niño could evolve into a "Super El Niño."
This development matters because such an intense event could trigger unprecedented heat waves in Europe, record-breaking ocean temperatures, and severe rainfall risks in Brazil. Climatologists said that climate change is amplifying the El Niño cycle, increasing the likelihood of these exceptionally strong events.
NOAA confirmed the onset of the 2026 El Niño on May 11 [3]. While some analysts said it is too early to definitively categorize the phenomenon's ultimate strength, NOAA estimates a 68% probability that the event will be "very strong" [1]. Some forecasts indicate this could be the most intense El Niño recorded in 140 years [2].
The impacts are expected to be felt globally throughout the remainder of 2026. In Brazil, the southeastern region is particularly vulnerable to increased rainfall. In Europe, the event is linked to the potential for unprecedented heat.
Experts said that "Super El Niño" is not an official technical classification, but the term is commonly used to describe events of this magnitude. The convergence of record ocean temperatures and shifted atmospheric patterns suggests a period of extreme instability—a trend that scientists link to broader global warming patterns.
Monitoring continues as the event progresses through the year. The potential for a "Super" classification depends on the sustained temperature anomalies in the central and eastern tropical Pacific Ocean.
“NOAA estimates a 68% probability that the event will be "very strong"”
The potential for a Super El Niño in 2026 highlights the volatile intersection of natural climate cycles and human-induced global warming. If the 68% probability of a 'very strong' event manifests, it will test the resilience of global agricultural systems and disaster response infrastructure, particularly in South America and Europe, where weather extremes are already becoming more frequent.
