Every El Nino is different, but the next could be hotter, bigger and far more unpredictable
Forecasters warn a potentially 'super' El Niño could form by July, with Pacific sea temperatures rising rapidly and a 20-30% chance of exceeding 2°C above average, though unpredictable wind patterns may alter its strength. Scientists say this event could amplify global heat records, particularly in 2026 or 2027, while its impacts—like droughts and extreme weather—may be intensified by climate change.
A major El Niño event is forming in the Pacific, with forecasters warning it could become one of the strongest on record. The U.S. National Oceanic and Atmospheric Administration (NOAA) estimates an 80% chance of El Niño developing by July, as sea temperatures in key equatorial zones surge rapidly. Several weather services predict temperatures could rise 2.5°C or more above average, surpassing the 2°C threshold seen in only three past events (1982/83, 1997/98, 2015/16). The UK Met Office’s Adam Scaife calls this a potentially record-breaking event, though its intensity remains uncertain due to unpredictable wind patterns. El Niño strengthens when ocean and atmosphere interactions shift air pressure and winds, but trade winds—critical for its development—have yet to weaken as expected. NOAA’s Michelle L’Heureux notes these winds can abruptly reverse, stalling or reversing El Niño’s growth. Even if weaker, this El Niño could push global temperatures to new highs, with 2026 or 2027 at risk of record heat. Past strong events (1998, 2016, 2023) followed similar patterns, but climate change may amplify its effects. Scaife warns impacts like droughts in the Amazon, Indonesia, and Australia—or disrupted Indian monsoons—could be more severe than ever. Scientists emphasize El Niño’s unpredictability, but its timing aligns with a warming planet, potentially worsening extreme weather. While its exact strength is unclear, the event’s global ripple effects—from heatwaves to rainfall shifts—could redefine climate risks in the coming years.
