El Niño 2026–27
Before, during and after El Niño, state by state
We track El Niño with NOAA's own index and follow the weather it tends to shift in your state: rain and snow, temperature, snowpack, drought, coastal water levels and wildfire. Real government data only. No forecasts dressed up as facts.

What this page is not
It is not a forecast for your state or property. El Niño shifts the odds; it doesn't decide the weather. Every number here is dated and comes from a named public source.
