The 2026 El Niño is expected to make unprecedented extreme weather patterns. Forecasting models lack the capability to anticipate these patterns at this time. It will may cause conditions that differ from past seasons. Forecasters say the lack of data makes it harder to guess storms, droughts, and heatwaves. Scientists observe sea surface temperatures in the Pacific. They expect effects to come over the coming months. Without good predictions, governments and communities need to stay alert to many impacts. Researchers aim to enhance their methods as new data is gathered. Right now, uncertainty is the primary aspect of the 2026 El Niño.
