Larimer County, CO — August 8, 2025
Residents across Northern Colorado are facing a triple threat this week: persistent wildfire smoke, extreme heat, and dangerous wildfire conditions.
Smoke and Health Warnings
Wildfire smoke drifting from western Colorado has pushed the Air Quality Index (AQI) in Larimer County above 150—unhealthy for all—prompting advisories from state and local health officials.
“If you can see or smell smoke, avoid outdoor activities—especially for children, seniors, pregnant individuals, and those with heart or lung conditions,”
— Tom Gonzales, Larimer County Public Health Director
Health precautions:
-
Monitor AQI updates at AirNow.gov
-
Stay indoors with windows closed; run AC on recirculate and use HEPA or DIY filters
-
Visit public air-conditioned spaces if your home becomes too warm
-
Seek medical help for wheezing, chest tightness, or unusual fatigue
Heat and Fire Threat Through Friday
Red Flag Warnings and Heat Advisories remain in effect for Larimer, Boulder, Weld, Jackson counties, and the Denver metro area.
Conditions fueling fire danger:
-
Temperatures 98–102°F
-
Winds 15–25 mph, gusts up to 40 mph
-
Humidity as low as 8–12%
Authorities urge residents to avoid any spark-producing activities and postpone strenuous chores until cooler hours.
