Wildfire Smoke Triggers Statewide Air Quality Alert in Wisconsin
31 Jul
Summary
- Millions urged to limit outdoor activities due to unhealthy air quality
- Smoke from Canadian wildfires degrades air conditions across Wisconsin
- Most air quality alerts issued in at least 4 years, raising health concerns
On August 1st, 2025, millions of people across Wisconsin were urged to limit outdoor activities due to dangerously poor air quality caused by smoke drifting in from Canadian wildfires. The Wisconsin Department of Natural Resources (DNR) issued a statewide air quality advisory, warning residents to stay indoors as fine particulate matter (PM2.5) levels reached "Unhealthy" and "Very Unhealthy" categories.
The advisory, initially set to expire on Thursday but later extended through Friday, highlighted the ongoing impact of severe wildfires beyond state borders. According to a DNR spokesperson, the agency has issued PM2.5 alerts for 16 days so far this year, the most in at least four years, raising concerns about the frequency and health implications of such air quality events in Wisconsin and the broader Midwest region.
Authorities urged vulnerable populations, including children, seniors, and those with heart or lung disease, to take extra precautions by limiting outdoor activities, moving events indoors, and using N95 masks if prolonged exposure is unavoidable. The DNR emphasized that air quality advisories are expected to continue throughout the summer as wildfires persist, underscoring the need for the public to remain vigilant and follow recommended safety measures.
