Weather & Climate

One of the first things newcomers notice about Fort Collins weather is the light. The city sits at 4,984 feet elevation on the Front Range of the Rocky Mountains — high enough to enjoy crisp, clean air and dramatic skies, but low enough to avoid the brutal winters of mountain towns like Breckenridge or Steamboat Springs. The climate alone convinces many people to begin moving to Fort Collins, Colorado.

Understanding Fort Collins Weather Through the Seasons

Fort Collins averages approximately 300 sunny days per year, which is more than Miami and more than Los Angeles. That sunshine is spread across four genuinely distinct seasons, each with its own appeal.

Spring arrives in March and April with warming temperatures, blooming wildflowers, and the occasional late snowstorm, but snow rarely lingers more than a day or two on the Front Range. Spring is ideal for hiking and cycling as the trails dry out from winter.

Summer runs from June through August with warm, dry days typically in the upper 80s°F, cool evenings perfect for patio dining, and afternoon thunderstorms that roll in from the mountains and clear by sunset. Humidity is low, making even hot days feel comfortable.

Fall is widely considered Fort Collins’ most beautiful season. September and October bring golden cottonwood trees, crisp air, CSU football, and some of the clearest skies of the year. First frost typically arrives in mid-October.

Sunshine, Snow, and Everything Between

Winter is mild compared to much of Colorado. Average January highs hover around 42°F, snowfall is moderate, and Chinook winds frequently warm the city dramatically, sometimes bringing 60°F days in December or January. Skiers and snowboarders are just 90 minutes from world-class resorts in the Rockies. The climate is often a deciding factor for those thinking about moving to Fort Collins.
