Denver's air quality today stands at **Moderate**, with a maximum Air Quality Index (AQI) of 60 driven by fine particulate matter (PM2.5) reaching 13 µg/m³ over a 24-hour period at the LNGM monitoring site.[1] This level, recorded around 4 PM yesterday, signals possible respiratory irritation for unusually sensitive individuals, though no advisories or indoor burning restrictions are in effect across the seven-county metro area.[2][1]

PM2.5, tiny particles smaller than 2.5 micrometers from sources like vehicle emissions, wood burning, and regional haze, is the primary culprit in the Denver Metro, mirroring moderate conditions in nearby Greeley (AQI 72, 20 µg/m³) and Grand Junction (AQI 60).[1] Ozone levels remain low, contributing to the overall moderate rating rather than unhealthy thresholds.[2]

Current real-time data shows stable conditions, with no spikes in other pollutants like nitrogen dioxide or carbon monoxide.[4][2] Forecasts predict good to moderate air through the weekend, aided by light winds around 3 m/s and temperatures near 7°C, which help disperse particles.[4] Visibility is good to moderate, free of dense fog or smoke.[1]

Interestingly, Denver's winter air often battles inversion layers trapping pollutants in the Mile High City's valley, but today's outlook avoids action days—mandatory restrictions triggered only for unhealthy AQI.[2] In 2025, 90% of days met WHO safe limits, underscoring the city's improving trends despite seasonal challenges.[3]

Residents, especially those with heart or lung issues, should limit heavy outdoor exertion if sensitive. Check apps like Love My Air for hyper-local updates.[6] Breathing easier today means enjoying Denver's crisp winter vibes responsibly. (248 words)

Denver's air quality today stands at **Moderate**, with a maximum AQI of 58 driven by nitrogen dioxide at the CAMP monitoring site.[1] This level poses minor risks, mainly respiratory irritation for unusually sensitive individuals, while the broader metro area reports good to moderate conditions overall.[1][2]

Real-time data from the Colorado Department of Public Health and Environment shows the I-25 Denver site at an AQI of 44 for PM2.5 particulates (7 µg/m³), placing it in the satisfactory range.[1] No air quality advisories or burning restrictions are in effect for the seven-county Denver-Boulder area, thanks to breezy, shifting winds dispersing pollutants.[2] Forecasts predict sustained good-to-moderate levels through the weekend, with lingering moderate PM2.5 pockets along the I-25 corridor and South Platte River.[2]

Nitrogen dioxide, peaking at 61 PPB around 10 AM MST, stems from vehicle traffic in this bustling urban hub.[1] Fine particulates like PM2.5, at low concentrations, arise from winter inversions trapping emissions amid the Rocky Mountain backdrop—Denver's high elevation (5,280 feet) naturally aids dispersion but winter stagnation can challenge it.[1]

Intriguingly, 2025 data reveals 90% of days in Denver met WHO safe limits, underscoring the city's resilient air despite its 3 million residents and heavy traffic.[4] Sensitive groups should limit heavy outdoor exertion, but most can enjoy crisp winter activities safely.[2]

Statewide, neighbors like Colorado Springs (AQI 35, good) and Fort Collins (AQI 42, moderate) mirror these trends, with no widespread concerns.[1] Breezes promise continued improvement, highlighting Colorado's proactive monitoring network.[1][2]

Denver’s air is generally clean today, with a touch of dust and wind-driven particulates that nudges conditions into the low end of the moderate range.

State and federal monitors show the Denver–Boulder region sitting near the border of good and moderate on the Air Quality Index, with a recent value around 50 to 55. The primary pollutant is coarse particulate matter, known as PM10, while fine particles (PM2.5) and ozone remain in the good range. This means the air is acceptable for most people, but a small fraction of individuals who are unusually sensitive to particle pollution could notice mild irritation in their eyes or lungs if they stay outside for long periods.

Weather is a big player today. A strong, dry west wind across the Front Range has created classic high-plains fire-weather conditions, with a red flag warning stretching along the I‑25 corridor. Those same gusty winds can loft dust and small debris into the air, explaining the bump in PM10 while other pollutants stay low. Forecasters also expect patchy blowing dust, especially late in the day and into the night, which can temporarily reduce visibility and make the air feel hazier than usual.

For healthy adults and children, normal outdoor activities are fine. People with asthma, COPD, or heart disease, along with older adults, may want to keep strenuous exercise brief if the wind is kicking up visible dust, and move workouts indoors if they notice coughing, wheezing, or shortness of breath.

The broader backdrop is reassuring: through most of this year Denver has enjoyed very low health risk from air pollution, with the vast majority of days falling within international health guidelines. Today continues that trend, offering mostly clean air with only a modest, wind-related uptick in dust.

Air over Denver this morning is generally in the good to low-moderate range, offering mostly healthy conditions for outdoor activities.[1][2][6]

State monitoring shows Denver Metro’s recent daily high Air Quality Index, driven mainly by coarse particulate matter, in the moderate category near 57–60.[1][2] A moderate AQI means the air is acceptable for most people, but very sensitive individuals – especially those with asthma, COPD, or heart disease – may notice mild symptoms during heavier exertion.[2]

There are currently no air quality advisories or indoor burning restrictions in effect for the Denver-Boulder metro area.[2][5] Forecasts from Colorado’s air quality division call for good to moderate conditions through the day, with breezy winds and decent atmospheric mixing helping to disperse pollutants.[2] Ozone, a summertime concern along the Front Range, is expected to remain in the good category, while fine particulate levels are forecast to stay low and within health-based standards.[2][6]

Regionally, a special health advisory is in place only for parts of northwestern and north-central Colorado due to wildfire smoke, not for Denver itself.[5] That smoke may contribute to some high-altitude haze, but major health impacts are not expected along the Front Range.[2][5]

For most residents and visitors, today is a favorable day to be outside in Denver. People who are unusually sensitive to air pollution may want to keep an eye on short-term AQI updates and consider easing off prolonged or vigorous outdoor exercise if levels edge into the higher end of the moderate range.[1][2]

Denver’s air today sits in the moderate range, meaning the air is generally acceptable but fine particle pollution is elevated enough that some unusually sensitive people could feel mild effects.[1][2][7]

State monitoring shows the Denver metro area with a daily maximum Air Quality Index around the low 70s, classified as Moderate, driven primarily by fine particulate matter known as PM2.5.[1] These particles are less than 2.5 micrometers in diameter, small enough to penetrate deep into the lungs and even enter the bloodstream. For most healthy adults, short-term exposure at this level is not expected to cause noticeable problems, and normal outdoor activities remain reasonable.

However, health agencies advise that people with heart or lung disease, older adults, children, and anyone who knows they are unusually sensitive to particle pollution take a bit of extra care.[2] That might mean watching for symptoms like coughing, shortness of breath, or unusual fatigue during heavier outdoor exertion, and easing back if they appear. For this group, limiting prolonged or very intense outdoor exercise during the hours when pollution peaks can reduce risk.[2]

There are no air quality advisories or indoor burning restrictions in effect for the seven-county Denver–Boulder area, reflecting expectations of good to moderate conditions through the day.[2][3] Ozone and other pollutants such as carbon monoxide and nitrogen dioxide are expected to remain in the good category, so today’s concern is focused almost entirely on fine particles rather than smog.[2][7]

In a broader context, Denver’s air in 2025 has often met international health guidelines, with the majority of days falling within the World Health Organization’s recommended limits, and an overall very low long-term health risk from air pollution.[5] Today’s moderate readings are a reminder that even in generally clean-air periods, fine particles can rise enough to matter for the most sensitive residents, while still allowing most people to enjoy outdoor life across the metro area.

Denver's Air Quality Today: A Moderate Saturday

Denver is experiencing moderate air quality conditions on this Saturday, November 29, 2025, with particulate matter being the primary concern. The Denver metro area recorded a maximum Air Quality Index (AQI) of 58, indicating moderate pollution levels that may affect sensitive individuals.

The primary pollutant affecting the region is fine particulate matter—particles smaller than 2.5 micrometers—at a concentration of 12 micrograms per cubic meter. This measurement was recorded early this morning at 3 AM Mountain Standard Time. While the general public faces minimal health risks, people with respiratory conditions such as asthma, children, and older adults should consider reducing prolonged or heavy outdoor exertion today.

The forecast outlook appears favorable. No air quality advisories are currently in effect for the seven-county Denver-Boulder metropolitan area, with conditions expected to remain stable through at least 4 PM today. Fine particulate matter concentrations are anticipated to improve to the Good category by tomorrow. Other pollutants including ozone, carbon monoxide, and nitrogen dioxide are all expected to remain in the Good range today and tomorrow.

Visibility conditions have been temporarily affected by light snow this morning, but meteorologists expect visibility to improve to Good by this afternoon as weather conditions clear.

Compared to other Colorado regions, Denver is experiencing relatively worse air quality. Colorado Springs, Pueblo, and the Colorado River Valley are all reporting Good air quality with AQI values well below 50. Only Fort Collins-Greeley approaches Denver's moderate conditions with an AQI of 56.

For context, Denver has maintained relatively healthy air quality throughout 2025, with 90 percent of the year's days falling within the World Health Organization's safe air quality limits. Today's moderate reading, while not ideal, remains within typical seasonal patterns for late November in the Denver metro area.

Residents concerned about air quality can check real-time monitoring data through the Colorado Department of Environmental Protection website, which updates air quality information continuously throughout the day.

Today’s air quality in Denver is mostly **moderate**, with some data sources reporting brief periods of higher pollution levels that may affect sensitive groups.

Official monitoring stations in the Denver Metro report a maximum Air Quality Index (AQI) value of **55**, classified as moderate and primarily driven by levels of fine particulate matter (PM2.5) at 11 micrograms per cubic meter. This means the air is generally acceptable for most people, but those who are unusually sensitive to air pollution, such as individuals with respiratory or heart conditions, young children, and older adults, may want to limit prolonged outdoor exertion. For most residents, outdoor activities remain safe, but noticing symptoms like coughing or throat irritation should prompt reducing time outside, especially for those in higher risk groups[1][7].

Air quality websites offer some variation in current readings. While local government sites and major sensors show moderate conditions, some national and international platforms, such as AccuWeather, rate the air as **“poor”** today, emphasizing that it can be **unhealthy for sensitive groups** and advising anyone feeling symptoms to minimize outdoor activity[2]. This discrepancy can be due to real-time spikes in pollution levels, differences in the types of pollutants measured, or the location of monitoring equipment.

The main pollutant driving today’s Denver AQI is **PM2.5**, tiny airborne particles that can irritate the eyes, nose, and respiratory tract. In general, long-term exposure to elevated PM2.5 can worsen existing heart and lung disease[1][7][8].

No official advisories are currently in effect for the Denver-Boulder area, and outlooks expect good to moderate conditions to continue through Monday afternoon. There are also burning restrictions in place due to visibility concerns but no widespread public health actions at this time[7][12].

Throughout 2025, Denver has experienced very few days above safe air quality limits. Over 90 percent of days have been within recommended health guidelines, making today’s moderate conditions a temporary exception rather than the norm[5].

Overall, air quality in Denver today is moderately impacted, especially by fine particulates, and most people can continue their normal routines, but those in sensitive health groups should monitor symptoms and limit strenuous activities outdoors.

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.

Denver’s air quality on Wednesday, November 12, 2025, reached a moderate level, mainly due to elevated concentrations of particulate matter. By 10 AM, the Air Quality Index, or AQI, climbed to 59 for particles less than 10 micrometers in diameter. This places Denver in the moderate category where air remains generally acceptable for most of the population but could prompt symptoms in those unusually sensitive to air pollution, such as people with existing respiratory illnesses or heart disease. If you fit these categories, consider limiting strenuous outdoor activity during peak hours today.

A notable factor today is the Action Day for Visibility declared across the Denver-Boulder metro area. This alert means indoor burning restrictions are now in place, and local officials are encouraging the public to limit driving of gas and diesel-powered vehicles. Visibility is forecasted to be especially poor during the afternoon, exceeding the state’s standard threshold for haze.

The moderate air quality was driven almost entirely by particulate matter, with a maximum concentration of 59 micrograms per cubic meter recorded during the day. No other air pollutants, such as ozone, carbon monoxide, or nitrogen dioxide, exceeded levels considered good according to state monitors. Ozone levels have remained in the good range, and no additional health advisories are in effect outside of particulate pollution and visibility reduction.

In summary, most people in Denver will not be directly affected by today’s air quality. However, if you are unusually sensitive to air pollution, especially fine particles, it is advisable to be cautious and avoid prolonged outdoor exertion. City officials remind residents to help improve air quality by minimizing activities that contribute to particle pollution, like using wood-burning stoves and unnecessary car trips, until the Action Day expires at 4 PM. For everyone else, today’s conditions mean it is a good day to stay mindful of visibility if you’re commuting, and to look out for updates if sensitivities or health risks apply to you[1][2].

Denver’s air quality today is expected to range from good to moderate, with no advisories or indoor burning restrictions in effect for the metropolitan region. Breezy winds combined with strong atmospheric mixing are allowing pollutants such as ozone, carbon monoxide, nitrogen dioxide, and fine particulate matter to remain at levels classified as either good or moderate for Saturday’s forecast period.

As of Friday afternoon, Denver’s highest measured Air Quality Index was 51 for fine particulates smaller than 2.5 micrometers. This falls into the moderate category, which means most people can go about their usual activities, but individuals who are unusually sensitive to particle pollution, such as those with heart or lung disease or older adults, may experience minor respiratory symptoms or aggravation of their conditions. In those cases, reducing heavy or prolonged exertion outdoors can be advisable.

Ozone concentrations are forecasted to be in the good range for both Friday and Saturday. Carbon monoxide and nitrogen dioxide are also expected to remain at good levels. Visibility is anticipated to be good to moderate for most of the day. These conditions are typical for the Front Range during this part of the year, aided by atmospheric mixing which disperses pollutants and limits buildup.

Historically in 2025, Denver has experienced generally healthy air: 90 percent of the days so far this year have met the World Health Organization’s safe air quality limits, indicating a very low risk for health problems from pollution. However, Denver remains on watch for ozone pollution, as periods of heat and wildfire smoke can trigger worse conditions—this summer, for instance, air quality advisories and action days were issued in response to high ozone and particulate levels.

For today, most residents and visitors in Denver should find outdoor conditions comfortable, but those with heightened sensitivity to air pollution may wish to take basic precautions, such as limiting strenuous outdoor activity during afternoon highs in particulate concentration.

Today, Denver’s air quality is generally considered good, with some periods of moderate levels, primarily due to fine particulate matter. For Saturday, November 1, 2025, there are no current air quality advisories issued for the Denver metro region, and the winter High Pollution Advisory Program has just begun. Officials will now monitor daily pollution levels more closely through winter to protect residents’s health[5][6].

The Air Quality Index (AQI) for Denver early this morning is in the good range, meaning pollution poses little or no risk for most people. Fine particulate matter, known as PM2.5, is the main concern this time of year. PM2.5 consists of tiny particles from sources like vehicles, fireplaces, and atmospheric conditions that can penetrate the respiratory system. While levels are not high enough to warrant an Action Day or burning restrictions as of now, individuals who are unusually sensitive to air pollution—such as those with chronic respiratory conditions, young children, or the elderly—should still monitor air quality forecasts[4][5].

The air in Denver during November is typically influenced by colder temperatures and atmospheric inversions, which trap pollutants close to the ground and can create the familiar “Brown Cloud.” This haze is made up of particulate matter and can impair visibility and affect respiratory health. The Colorado Department of Public Health and Environment (CDPHE) issues daily air pollution advisories, calling for voluntary driving reductions or indoor burning restrictions whenever conditions exceed standards[3].

Ninety percent of the days so far this year in Denver have been within safe air quality limits, indicating a very low health risk for most residents. However, occasional spikes in pollution—most commonly during stagnant weather or when wildfire smoke drifts from other states—can temporarily elevate particulate matter and ozone, prompting caution for sensitive groups[2][3][4].

Overall, the city’s air is safe for outdoor activity today, but the start of winter could bring more frequent advisory periods, particularly on calm days when pollution builds up. Denver residents are encouraged to stay informed through state forecasts, reduce unnecessary burning, and help limit emissions on poor air days to protect community health[3][5].

Denver’s air quality today is in the Moderate range, with the highest recorded Air Quality Index, or AQI, reaching 68 for particulate matter less than 10 micrometers early in the morning. Throughout much of the city, the AQI has hovered between the high 50s and mid 60s, primarily driven by fine particulate pollution. Ozone and other pollutants remain in the Good category.

Moderate air quality means that air pollution levels are acceptable for most people, but there is a slight risk for individuals who are unusually sensitive to airborne particles, such as those with respiratory or heart conditions. These individuals should consider reducing prolonged or heavy outdoor exertion, especially if they notice symptoms like coughing or throat irritation.

No air quality advisories are currently in effect for Denver or the surrounding Front Range Urban Corridor. Carbon monoxide and nitrogen dioxide remain well within Good levels, and ozone is expected to remain in the Good category through the weekend. The highest particulate concentrations were seen near the South Platte River corridor, from Denver northward, but pollution levels are projected to improve in the coming days.

In terms of visibility, conditions are likely to be moderate to poor at times on Saturday in the Denver area, with improvements expected beginning Sunday. The overall health risk for the Denver area today is considered very low for the general population, and 90 percent of the year’s days so far have been within the World Health Organization’s recommended air quality guidelines.

Outdoor activities can proceed as usual for most of Denver’s residents, though those with heightened sensitivity may wish to monitor symptoms and remain indoors during periods of increased particulate matter, especially during the early morning hours when daily AQI tends to peak. For most, today’s air remains suitable for work, school, and recreation outdoors.

For these sensitive groups, including those with respiratory conditions, reducing prolonged or heavy outdoor activity from noon to 8 PM is recommended, though most residents will not be affected.

Ozone levels are forecasted to remain in the good to moderate range both today and tomorrow. Particulate matter, carbon monoxide, and nitrogen dioxide concentrations are all expected to stay in the good category through Tuesday, indicating that overall air pollution remains relatively low in Denver. Furthermore, visibility is expected to stay good throughout Tuesday.

Over the past 24 hours, the highest recorded AQI in Denver reached 71 at 6 AM, while the lowest point was 34 at 9 PM, reflecting a decrease in pollution as the day progressed. Fine particulate matter concentrations, which are one of the main pollutants, are expected to continue dropping due to unsettled weather and shifting winds moving smoke out of the Denver area.

No air quality advisories or Action Days are currently in effect for the Denver metro and the broader Front Range region. The Colorado Department of Public Health and Environment does not anticipate needing any short-term advisories, so the risk from air pollution will remain low for most people today and tomorrow.

Denver residents can expect generally clean air with only minor concerns for sensitive individuals until conditions change. Unusually sensitive groups should stay aware, especially during peak midday hours when pollution tends to be highest, but for the general public the air quality is expected to be good.

Denver’s air quality today is in the moderate range, with an Air Quality Index (AQI) of 81 for fine particulate matter reported around 7 AM MDT. Visibility across the metro area is somewhat reduced, with hazy skies due to wildfire smoke drifting from active fires in the Pacific Northwest and Canada. The National Weather Service and state agencies have confirmed most of the smoke is aloft, but there are still concerns for sensitive populations. People with heart or lung conditions, older adults, and children should consider reducing prolonged or heavy outdoor exertion.

The recent weather trend shows Denver’s AQI fluctuating between around 50 and 80 in the past several days, reflecting a mix of local and external wildfire influences. While a grass fire in Arvada occurred yesterday, local meteorologists report that it is not significantly impacting Denver’s air; the haze is almost entirely coming from outside the region. According to satellite imagery, conditions are expected to gradually improve through the weekend as smoke moves south and clears from the Front Range.

On Colorado’s Western Slope, air quality remains in the healthy or “green” category, since wildfire smoke there is staying higher in the atmosphere and not affecting ground-level conditions. The Denver-Boulder corridor is currently experiencing the worst air quality in the state, with elevated PM2.5 concentrations driven primarily by long-range transport of wildfire particles.

There is a health advisory for portions of northwestern and north-central Colorado regarding wildfire smoke. For Denver specifically, no surface-level air quality advisories are currently in effect, but officials continue to monitor updates and encourage residents to stay informed.

For those concerned, staying indoors during smoky periods, using air filters, or following public health guidance can help minimize exposure. Denver’s air quality is likely to improve as the weekend progresses, but today, moderate levels of wildfire smoke should prompt precautions among sensitive groups.
