Summer is still in full swing in Illinois, with no end in sight to the 90-degree days, according to the National Weather Service.
Fortunately, fall is expected to bring reprieve to many Illinois residents seeking cooler weather.
The Old Farmer’s Almanac published its fall 2026 weather forecast, predicting warmer temperatures in the interior parts of the country bordered by cooler-than-average temperatures in surrounding areas.
Rainfall is expected to be lower than normal in most of the United States, excluding the West Coat and parts of Texas, Florida and the Northeast.
Here’s how the fall forecast looks for Illinois.
Old Farmer’s Almanac fall 2026 forecast for Illinois
Northeast Illinois is forecast to see cooler-than-average temperatures and near-average rainfall in September, with precipitation dropping slightly and temperatures returning closer to normal in October.
Southern Illinois will likely see a similar temperature pattern, as well as up to three inches less rainfall than normal.
Northwest Illinois is expected to be warmer than average with a dry September and up to one more inch of rainfall than normal in October.
NOAA fall 2026 forecast for Illinois
The National Oceanic and Atmospheric Administration predicts equal chances of above-normal, near-normal or below-normal temperatures and precipitation in Illinois between September and November.
This means there are no strong signs yet indicating one possibility over the others.
For much of the rest of the country, the NOAA forecasts above-normal temperatures and precipitation.
