A historically strong "Super" El Niño is forming in the Pacific Ocean and is expected to develop by fall or winter 2026 [1, 3].
This development is critical because the pattern can disrupt global weather systems, threatening food security, and increasing the risk of extreme weather events. The scale of this event is expected to be significant, potentially affecting hundreds of millions of people worldwide [2].
El Niño is a natural climate pattern characterized by the warming of surface waters in the eastern Pacific. However, researchers said that climate change may be amplifying these cycles, leading to more widespread and intense impacts than seen in previous decades [1, 4].
Forecasts suggest the event is arriving faster than expected [3]. This accelerated timeline reduces the window for governments and agricultural sectors to implement mitigation strategies. The peak strength of the event is projected for 2026 [3].
Historical data from previous "Super" El Niños provide a roadmap for potential consequences. These include severe flooding in some regions and intense droughts in others, which can devastate crops and displace populations. Because the current pattern is being intensified by a warming planet, the resulting weather extremes may exceed historical norms [1, 4].
Monitoring agencies continue to track sea surface temperature anomalies in the Pacific to refine the timing of the peak. The interaction between this natural cycle and human-induced warming creates a volatile environment for global climate stability [1].
“Potentially affecting hundreds of millions of people worldwide”
The emergence of a Super El Niño during a period of accelerated global warming suggests a compounding effect. While El Niño is a recurring natural phenomenon, its intersection with rising baseline global temperatures may increase the frequency and severity of extreme weather, making historical precedents less reliable for future planning.
