Researchers from NOAA and climate scientists warn that unusual warming in the Pacific Ocean may trigger a "super" El Niño in 2026 [1, 2].
This development is critical because a super El Niño can disrupt global weather patterns, potentially leading to record-strong hurricane seasons and severe droughts across different continents [3].
Data from the central and eastern equatorial Pacific show sea-surface temperature anomalies rising more than two degrees Celsius above normal [1, 4]. This specific temperature threshold is the marker for a “super” El Niño event [1]. Scientists said that the current weakening of La Niña, combined with warming driven by climate change, is amplifying the feedbacks that fuel this phenomenon [1, 5].
"A super El Niño may form in 2026 amid unusual Pacific warming, raising the risk of extreme global weather patterns," a NOAA spokesperson said [1].
While some data suggest the event could reach "very strong" levels later this year, other experts urge caution regarding the timeline [6]. A staff writer for Phys.org said that while talk of a super El Niño is gaining momentum, it is still too early to forecast one with certainty [2].
The unpredictability of these events is increasing as global temperatures rise. Raymond Zhong said that past episodes of the natural weather phenomenon may no longer be a reliable guide of how the next one plays out [5].
Monitoring continues as the region enters the summer and winter of 2026 and 2027 [1, 2]. The 2026 hurricane season is specifically flagged as a period that could be intensified by these ocean conditions [3].
“A super El Niño may form in 2026 amid unusual Pacific warming, raising the risk of extreme global weather patterns.”
The potential for a super El Niño highlights the increasing volatility of global climate systems. Because climate change is amplifying natural feedbacks, traditional historical models may no longer accurately predict the severity or duration of these events, making early detection and adaptive infrastructure more critical for disaster mitigation.
