The 2026 El Niño is poised to bring about novel extreme weather patterns. Forecasting models are unable to forecast these patterns at this time. It will likely bring conditions that differ from past seasons. Forecasters say the lack of data makes it more difficult to predict storms, droughts, and heatwaves. Scientists observe sea surface temperatures in the Pacific. They anticipate impacts arriving over the subsequent period. Without good predictions, governments and communities should be prepared to multiple consequences. Researchers aim to enhance their methods as new data is gathered. Right now, uncertainty is the key feature of the 2026 El Niño.
