NOAA Predicts 'Super' El Niño Likely by Late 2026, Warning of Severe Global Impacts

The National Oceanic and Atmospheric Administration (NOAA) forecasts a 65% probability of a strong or very strong El Niño developing between October 2026 and February 2027. This potential "super" El Niño, characterized by a significant rise in Pacific sea surface temperatures, could rank among the most intense events recorded since the 1870s. The certainty of this occurrence has increased significantly from previous months, with an 82% chance of onset by July 2026. Experts warn that such an event could exacerbate global warming, potentially making 2027 the hottest year on record. The humanitarian consequences may be severe, including disrupted fisheries, reduced crop yields, and heightened risks of wildfires and hurricanes. Historical parallels to the catastrophic 1877-1878 El Niño, which contributed to a global famine killing millions, highlight the potential for widespread food and water insecurity. With warmer baseline ocean and atmospheric temperatures today, climate scientists caution that associated weather extremes could be more intense than in past centuries, posing significant threats to economic stability and vulnerable populations worldwide.
