Is the air quality good in Detroit?
As of February 16, 2026, at 3:30 AM Pacific Time, Detroit, Michigan, is experiencing poor air quality due to melting snow releasing trapped particulate pollution back into the atmosphere (1). The Air Quality Index is 157, which falls within the "unhealthy" range.
An Air Quality Advisory remains in effect across Southeast Michigan, including Detroit, because of elevated levels of fine particulate matter PM2.5 (1). The advisory is scheduled to remain in place until 12:00 PM on February 16.
During this advisory period, residents should limit strenuous outdoor activity. Sensitive groups, including children, older adults, and individuals with heart or lung conditions, should avoid prolonged outdoor exposure. Keeping windows closed and using high efficiency air filtration systems indoors can also help reduce exposure to fine particles.
Air quality conditions can change rapidly throughout the day. For a complete, real-time view of current pollution levels, see Detroit's air quality map.
While the air quality conditions today are unusually poor, it is important to keep in mind that the average PM2.5 concentration in 2024 for Detroit was 8.4 µg/m³. This corresponds to an AQI of 47, which falls into the "good" category and was 1.68 times the WHO annual guideline.

What is causing poor air quality in Detroit?
The poor air quality in Detroit is primarily caused by melting snow releasing trapped particulate pollution back into the atmosphere (3).
Throughout the winter, fine particles such as vehicle emissions, industrial pollutants, dust, road salt, and organic compounds become trapped in accumulated snow (4). As temperatures rise above 50 degrees Fahrenheit, rapid snowmelt releases these particles into the air (5).
Light winds and limited atmospheric dispersion are allowing PM2.5 concentrations to build up, particularly in densely populated areas like Detroit (6).
