Denver’s air quality today is classified as moderate, with primary concern stemming from elevated levels of particulate matter less than 10 micrometers in diameter. The highest recorded Air Quality Index, or AQI, reached 81 in the Denver metro area early this morning, driven mainly by fine particles from vehicle emissions, construction dust, and other urban sources. The concentration measured was 115 micrograms per cubic meter over a 24-hour period, which places some sensitive groups at risk for mild respiratory symptoms. For most people, breathing in Denver today will not cause any noticeable effects, but individuals with existing heart or lung conditions, older adults, or anyone unusually sensitive to air pollution should limit strenuous outdoor activities until conditions improve.

Visibility has also been a concern, meeting thresholds that prompted local officials to declare an Action Day for Visibility. Restrictions on indoor burning are in effect until late afternoon, and authorities encourage residents to refrain from unnecessary driving to help reduce particle pollution and haze. Other air pollutants, such as ozone, carbon monoxide, and nitrogen dioxide, remain well within safe ranges citywide. Ozone levels have held steady in the “good” category, with no notable spikes in gases or additional advisories except for particle pollution and visibility concerns.

Historically, Denver’s air quality remains within World Health Organization safe limits on nine out of ten days. Today’s moderate status is typical for this time of year, when colder weather leads to temperature inversions and air pollution can accumulate near the ground. Officials expect conditions to improve by tomorrow as forecast particulate and visibility levels trend downward, allowing for normal outdoor activity for all residents.

In summary, while Denver’s air is not pristine today, it is generally safe for healthy adults and children. Those with sensitivities should reduce heavy exertion outdoors, and all residents are encouraged to minimize activities that contribute to particulate buildup. Stay informed and check updates if you plan to spend extended time outdoors, especially if visibility is poor during afternoon commutes.
