The 2026 El Niño is poised to make novel extreme weather patterns. Forecasting models lack the capability to anticipate these patterns at this time. It will probably introduce conditions that differ from past seasons. Forecasters note the lack of data makes it harder to guess storms, droughts, and heatwaves. Scientists monitor sea surface temperatures in the Pacific. They look for outcomes emerging over the next few months. Without good predictions, governments and communities should be prepared to various effects. Researchers hope to improve their tools as new data becomes available. Right now, uncertainty is the key feature of the 2026 El Niño.
