2026 Fall Weather Outlook: What to Expect Across the United States

As we approach fall 2026, understanding the expected weather patterns can help you prepare for the season ahead. Here's what to anticipate across the United States:

What is the El Niño phenomenon, and how will it affect fall 2026 weather?

El Niño refers to the warming of sea surface temperatures in the central and eastern Pacific Ocean, which influences global weather patterns. In June 2026, the National Oceanic and Atmospheric Administration (NOAA) officially declared the onset of El Niño conditions, with expectations of a strong event persisting through at least the end of 2026.

How will El Niño impact temperatures across the U.S. in fall 2026?

El Niño typically brings warmer-than-average temperatures to many regions. The North American Multi-Model Ensemble (NMME) forecasts indicate that global temperatures will rise well above 1.5°C above the 1850-1900 preindustrial baseline by the end of 2026, likely influenced by the developing El Niño conditions.

What are the precipitation expectations for fall 2026?

Precipitation patterns during El Niño events can vary:

  • Southern U.S.: Historically, El Niño brings wetter conditions to the southern states. The NMME forecasts suggest increased probabilities of above-normal precipitation in the southwestern United States and Mexico during the fall. (iri.columbia.edu)

  • Northern U.S.: Conversely, the northern regions may experience drier conditions. The same NMME forecasts indicate increased probabilities of below-normal precipitation in parts of central North America, including the northern United States and southern Canada, during the fall.

  • North Central: Cold late-November weather is expected, with light snow possible in the northern Plains and Rockies, especially at higher elevations. (farmersalmanac.com)

  • South Central: Mostly seasonable overall, with cooler conditions inland; western and higher-terrain areas may trend colder, but widespread storminess does not stand out right now. (farmersalmanac.com)

  • Northwest: Expect typical late-fall weather, with periods of rain in the Northwest and wet roads possible for travelers. (farmersalmanac.com)
