The 2026 El Niño is poised to cause new extreme weather patterns. Forecasting models lack the capability to anticipate these patterns at this time. It will likely bring conditions that differ from past seasons. Forecasters note the lack of data makes it challenging to foresee 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 must remain vigilant to multiple consequences. Researchers hope to improve their tools as new data becomes available. Right now, uncertainty is the main characteristic of the 2026 El Niño.
