A 'super' El Niño is developing, with scientists predicting it could become one of the strongest on record by the end of
El Niño, part of the El Niño Southern Oscillation (ENSO) cycle, is characterized by warmer-than-average sea surface temperatures in the eastern equatorial Pacific. The U.S. National Oceanic and Atmospheric Administration (NOAA) confirmed the onset of El Niño on June 11, 2026, and forecasts a 63% chance of it reaching 'super' status by winter, with sea surface temperatures exceeding 2°C (3.6°F) above average. This phenomenon is expected to significantly impact global weather patterns, including increased Pacific cyclones, altered jet streams, and potential heat-related health risks. Historical comparisons suggest this event could rival the record-breaking 1997-1998 El Niño.

Impact & Risks

The developing super El Niño is expected to have widespread impacts, including extreme weather events such as severe droughts, heavy rainfall, and intense heat waves. In the United States, more frequent and intense Pacific cyclones are anticipated, while Atlantic hurricane activity may decrease due to altered wind patterns. Globally, the event could exacerbate heat-related illnesses and vector-borne diseases like malaria and cholera. Agricultural sectors may face challenges, with potential crop failures in some regions due to drought or flooding. The economic toll could be significant, as past strong El Niño events have caused billions in damages worldwide.
