How will the 2026 Super El Niño affect my area?

Impacts vary by region. Enter your city or ZIP code on El Niño Impact to see projected rainfall and temperature changes, the most likely hazards (flooding, storms, drought, or wildfire), live weather, and any active alerts for your location.

When will the 2026 El Niño have the strongest effects?

El Niño effects in the U.S. are typically strongest during the winter months, roughly December through March, though the peak window differs by region.

Where does El Niño Impact get its data?

Live weather and alerts come from NOAA's National Weather Service, and El Niño strength uses NOAA's official Oceanic Niño Index (ONI). Regional impact estimates are grounded in documented El Niño climatology.
