Denver’s air quality this morning is rated mostly as Good, with localized areas experiencing Moderate levels of particulate matter. The Air Quality Index, or AQI, for ozone at the latest reporting times remained in the Good range, indicating that ozone pollution currently poses little risk to the general population. Specifically, recent measurements show ozone AQI values around 48 to 50, which means the air is considered satisfactory and should be safe for most residents.

However, particulate matter known as PM2.5 has been measured at an AQI of 66, which falls into the Moderate category. For most people, this level of particulate pollution is not a health concern. Nevertheless, unusually sensitive individuals, such as those with previous heart or lung disease or older adults, may begin to experience minor respiratory symptoms or worsening of existing conditions. These groups are encouraged to limit prolonged or heavy outdoor exertion during periods when PM2.5 is elevated.

No Ozone Action Day Alerts are currently in effect for Denver and the surrounding counties as of this morning. The Colorado Department of Public Health and Environment indicates that air pollution levels will likely remain steady through the early afternoon, with no major advisories or warnings for heightened risk expected at least until 4 p.m. today.

Residents in the greater Denver-Boulder area can expect overall clean air conditions for outdoor activities throughout most of the day. Still, monitoring advisories is recommended for those in sensitive groups as air quality can change throughout the afternoon, especially if temperatures rise or weather conditions stagnate.
