Temperature Predictions: Will Fall Feel Warmer or Colder?

The Old Farmer's Almanac just released its new fall forecast for 2025, providing Western Colorado's first look at the season's likely temperatures and precipitation totals. So far, it's been a warm year in places like Grand Junction, Delta, and Montrose.

This fall, most of Colorado can expect continued warm and dry conditions according to the Almanac. Temperatures around the state should average three to four degrees warmer than usual. September rainfall could be below average, and October rainfall appears normal for Western Colorado.

Precipitation Outlook: Rain, Snow, or Dry Spells?

Precipitation levels in Colorado are expected to be slightly below normal in September and October. The Old Farmer’s Almanac says Grand Junction, Fruita, and Palisade should be on the lookout for monsoonal storms in September, but conditions seem only to favor occasional storms. October should feature a few cold-rain events, while any measurable snow in the valley is more likely a late November affair.

Snow showers could hit the San Juan Mountains (Telluride, Ouray, Silverton) as early as late September, with the snowpack beginning to establish by late October. Light snow may dust the Grand Mesa by early October, but wet snow and rain are more likely. Areas like the Flat Tops and Gunnison National Forest could see multiple early-season snows.
