The best time to go to Fort Collins is during the late spring, summer, and early fall, from May through October, when the weather is warm and conducive to outdoor activities.
May and early June offer pleasant temperatures, typically in the 60s and 70s Fahrenheit, making them ideal for exploring the natural areas surrounding the city, such as the Horsetooth Reservoir or hiking trails in the foothills. This period is great for couples who enjoy outdoor adventures without the peak summer crowds.
July and August are the warmest months, with average temperatures in the 80s, superb for enjoying the Poudre River for tubing or rafting, and participating in local festivals. Families will find these months particularly appealing, as many attractions offer extended hours and the weather is consistently sunny for park visits and outdoor dining.
September and October bring cooler temperatures, generally in the 60s, and the beautiful fall foliage.
