The Michigan Department of Environment, Great Lakes, and Energy (EGLE) has issued an Air Quality Advisory for Houghton Lake and surrounding areas for Thursday, June 5 and Friday, June 6, due to smoke from Canadian wildfires pushing fine particulate matter (PM2.5) to unhealthy levels.
- Thursday, June 5: AQI 120 – Unhealthy for Sensitive Groups (Orange)
- Friday, June 6: AQI 140 – Unhealthy for Sensitive Groups (Orange)
The advisory covers the Eastern Upper Peninsula and all of Northern Lower Michigan, generally north of a Ludington-to-Midland line.

Extended Outlook:
- Saturday, June 7: Still unhealthy for sensitive groups (Orange)
- Sunday, June 8: Unhealthy for sensitive groups (Orange)
- Monday, June 9: Good (Green)

Health Advisory:
Sensitive individuals—such as children, the elderly, and those with respiratory or heart conditions—should limit outdoor activities during this period.
Tips to Protect Yourself and Improve Air Quality:
- Close windows overnight to keep indoor air cleaner
- Run central air conditioning with a MERV-13 or higher filter, if available
