Smoke from Canadian wildfires brings unhealthy air to large swaths of the Midwest
MIDWEST UNITED STATES, AUG 2 – Over 667 wildfires in Canada have burned more than 16 million acres, causing unhealthy air quality across multiple Midwest states through the weekend, officials said.
- Smoke from hundreds of ongoing wildfires in Canadian provinces has created unhealthy air conditions across large parts of the U.S. Midwest since late July 2025.
- The wildfires burning over 16 million acres in Saskatchewan, Alberta, and Manitoba have sent smoke repeatedly into the U.S., worsening air quality across multiple states.
- Air quality alerts remain in effect for Minnesota, Wisconsin, Michigan, Iowa, and nearby states, with Minneapolis and Chicago experiencing some of the world's worst pollution levels since July 31.
- The Air Quality Index is expected to stay in the unhealthy red zone through Saturday, with values rising above 100 and even reaching the 160s, representing risks for sensitive groups.
- Health officials advise vulnerable populations to limit outdoor exposure and strenuous activities while smoke is expected to linger through the weekend before conditions slowly improve.
