El Niño Set to Top 3°C in September as Strongest Event on Record

3 articles · Updated · The Washington Post · Sep 3

Summary

  • Climate models now show Niño 3.4 rising from about 2.6°C above average to more than 3°C within weeks, likely making this El Niño the strongest on record and keeping it near peak strength through February.
  • A 6,000-mile swath of the equatorial Pacific has warmed sharply after western Pacific wind shifts pushed a vast pool of hot water eastward, reinforcing the event.
  • That warming has already been linked to a destructive Hawaii hurricane and a moister atmosphere this summer, raising the odds of extreme rainfall and oppressive humidity.
  • This fall and winter, the pattern is expected to strengthen the southern U.S. jet stream, increasing the risk of frequent powerful storms from California to the East Coast.
  • The WMO said the event could peak near year-end and amplify global heat into 2027, worsening risks of floods, drought and extreme heat for communities and economies.

2026 Super El Niño Reaches Record Intensity: Global Impacts, Ecological Collapse, and Policy Responses

Overview

The 2026 Super El Niño began with weakened and reversed equatorial trade winds, which triggered massive Kelvin waves moving warm water eastward. This deepened the warm surface layer and suppressed the upwelling of cold, nutrient-rich waters, leading to a huge subsurface heat reservoir. As this heat rose, El Niño conditions intensified and persisted, causing dramatic atmospheric changes like a weakened Walker circulation and shifting wind patterns. These shifts increased wind shear in the Atlantic, suppressing hurricanes, while the alignment of El Niño with other ocean events heightened droughts and floods. Meanwhile, ocean warming blocked nutrient flow, disrupting marine life and weakening the ocean’s ability to absorb carbon dioxide.
