El Niño Drives 20-Plus Days of Record Pacific Heat as 2026-27 Event Threatens Top-5 Strength
3 articles · Updated · USA TODAY · Jun 25
Summary
More than 20 days of daily Pacific sea-surface heat records in June have pushed El Niño into what scientists say could become one of the strongest events on record.
Upper-ocean temperatures in the central and eastern equatorial Pacific are already more than 3 degrees above normal, with NOAA and other forecasters expecting the event to peak between November and January.
That warming can shift trade winds, jet streams and rainfall worldwide, raising risks of flooding, landslides, wildfires and coral bleaching while also easing some drought and reducing Atlantic hurricane activity.
California could see temporary sea-level increases of 6 inches or more on top of long-term coastal rise, worsening flood risk when winter storms and high tides align.
Scientists say El Niño may help make 2026 or 2027 the hottest year on record, and research suggests the 2026-2027 episode could bring global losses in the trillions of dollars.
As El Niño amplifies record global heat, are we entering a new era of unpredictable climate disasters?
With trillions in losses predicted, can our forecasts truly prevent the costliest El Niño in history?
The 2026-27 Super El Niño: Unprecedented Intensification, Global Impacts, and Urgent Adaptation Needs
Overview
As of June 2026, a rapidly intensifying El Niño is developing into a potentially historic event, with current observations showing a heavily structured footprint across the equatorial Pacific Ocean. This footprint signals a growing influence on global weather patterns, as extreme probabilities for above-normal sea surface temperatures dominate the region east of the Date Line, especially in the Niño 3.4 area. These severe sea surface temperature anomalies highlight the seriousness of the situation and suggest that this El Niño could have far-reaching impacts, making it one of the most significant climate events in recent history.
