The 2026 El Niño is poised to bring about new extreme weather patterns. Forecasting models can't predict these patterns currently. It will probably introduce conditions that are unlike past seasons. Forecasters note the lack of data makes it challenging to foresee storms, droughts, and heatwaves. Scientists watch sea surface temperatures in the Pacific. They anticipate impacts arriving over the next few months. Without good predictions, governments and communities need to stay alert to various effects. Researchers seek to upgrade their systems as new data is gathered. Right now, uncertainty is the key feature of the 2026 El Niño.
