The 2026 El Niño is poised to make unprecedented extreme weather patterns. Forecasting models are unable to forecast these patterns at this time. It will may cause conditions that are unlike past seasons. Forecasters indicate the lack of data makes it more difficult to predict storms, droughts, and heatwaves. Scientists monitor sea surface temperatures in the Pacific. They expect effects to come over the next few months. Without good predictions, governments and communities should be prepared to many impacts. Researchers aim to enhance their methods as new data comes in. Right now, uncertainty is the key feature of the 2026 El Niño.
