Denver's air quality today, March 6, 2025, is reported as Good to Moderate, with some areas experiencing Poor conditions. The highest Air Quality Index (AQI) value recorded was 55, indicating Poor air quality due to elevated levels of nitrogen dioxide (NO2)[5].
The Colorado Department of Public Health and Environment forecasts Good to Moderate air quality conditions for ozone and fine particulate matter (PM2.5) through Monday[3]. No advisories or restrictions are currently in effect for the Denver metro area.
Despite improvements since the 1970s and 1980s when Denver violated air quality standards up to 200 days a year, the city continues to face challenges with air pollution, particularly ozone[2]. Denver's unique geography, nestled against the Rocky Mountains, can trap pollutants and create a visible haze known as the "brown cloud"[2][4].
Current pollutants of concern include NO2, PM2.5, and PM10, all registering in the Fair to Poor range[5]. Ground-level ozone, while currently at Fair levels, remains a persistent problem during summer months[4][5].
Health experts advise reducing time spent outdoors if experiencing symptoms such as difficulty breathing or throat irritation, especially for sensitive groups[5]. The risks are heightened during exercise, as increased breathing rates can lead to greater exposure to pollutants[6].
Denver's air quality is influenced by various factors, including vehicle emissions, industrial activities, and regional wildfires[2][6]. Ongoing efforts to improve air quality focus on reducing emissions from these sources and implementing stricter environmental regulations[4].
Residents can stay informed about air quality conditions through local forecasts and real-time monitoring data available online and through mobile applications[3][5][7].
