The 2026 Colorado wildfires are a series of active wildfires currently ongoing in Colorado.
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.
