Ozone Alert Days in Denver | Denver News

Ozone Action Alert Days mean ground-level ozone — a sneaky, invisible lung irritant — is high, especially in Denver’s valley where heat and trapped pollutants make it worse. Wildfires can help, but clear skies don’t guarantee clean air. Kids, seniors, and those with lung issues are most at risk, with long-term exposure tied to serious health problems. Stay indoors during peak hours, avoid strenuous outdoor activity, and reduce driving — because vehicle emissions fuel the problem. Alerts run May through August, and hot, dry weather spikes risk — so check your phone’s air quality app, but remember: ozone doesn’t show up in photos, but it sure shows up in your lungs.
