The 2026 Colorado wildfire season has included a significant number of wildfires in Colorado.

Background

While "fire season" varies every year in Colorado, most wildfires occur in between May and September. However, there is an increasing fire danger in winter months. Fire conditions can be exacerbated by drought, strong winds, and vegetation growth. Climate change is leading to increased temperatures, lower humidity levels, and drought conditions are happening more often. Additionally, warmer temperatures and less precipitation can result in less snowmelt, further contributing to bad wildfire conditions.

Colorado had one of its lowest snowpacks on record during the 2025-26 North American winter due to warm and dry conditions, particularly in the western part of the state. These conditions left Colorado more vulnerable to wildfires then usual.

During June 2026, multiple major wildfires sparked across the southern half of the state a few days after wildfires in Utah exploded in size and intensity, with the Aspen Acres Fire growing to be the largest in the state, and more favorable weather conditions have damage assessments ongoing across the area.
