Super El Niño Likely to Develop by Fall 2026, NOAA Reports
Super El Niño Likely to Develop by Fall 2026, NOAA Reports
US · Published May 15, 2026
El Niño conditions are forming faster than anticipated in the Pacific Ocean, with increasing odds of a historically strong 'Super El Niño' developing by fall or winter
According to NOAA's Climate Prediction Center (CPC), there is a 96% chance that El Niño will persist through the winter, with a one-in-three likelihood of reaching 'Super' status. This phenomenon occurs when sea-surface temperatures in the equatorial Pacific rise significantly above average, influencing global weather patterns. Currently, water temperatures are just below the 0.5°C threshold for El Niño classification but are expected to surpass it by next month. A vast pool of warm water in the central and eastern Pacific is anticipated to surface, further intensifying the event. Historically, Super El Niños have caused significant global impacts, including droughts, heatwaves, and flooding, while also amplifying global temperatures already elevated by climate change.

Why It's Important?

A strong or Super El Niño could have widespread effects on global weather. Regions such as the Caribbean and Southeast Asia may experience drought, while the southern United States could see wetter and cooler conditions during winter. Conversely, the northern U.S., western Canada, and Alaska are likely to experience warmer-than-average winters. El Niño also tends to suppress hurricane activity in the Atlantic while increasing it in the central and eastern Pacific, potentially threatening Hawaii and the U.S. Southwest. Additionally, global temperatures are expected to rise further, with 2026 or 2027 potentially becoming the warmest years on record. These changes could exacerbate wildfire risks, water shortages, and agricultural challenges in affected areas.
