Mountain West Sees Increase in Fire Weather Days Due to Climate Change
US · Published May 19, 2026
A recent analysis highlights a significant rise in 'fire weather days' across the Mountain West region, attributed to climate change.
Fire weather days are defined by a combination of hot, dry, and windy conditions persisting for at least two hours in a day.
According to Kaitlin Trudeau, an applied climate scientist with Climate Central, the fire season in many areas has extended by up to two additional months compared to the 1970s.

Why It's Important?

The growing number of fire weather days poses significant risks to communities across the Mountain West. Wildfires are becoming larger and more destructive, threatening lives, property, and ecosystems. Prolonged fire seasons also strain firefighting resources and increase the likelihood of power shut-offs to prevent fire ignitions. Additionally, the smoke and particulate matter from these fires can lead to unhealthy air quality, exacerbating respiratory and cardiovascular issues, particularly for vulnerable populations such as children, the elderly, and those with pre-existing health conditions.
