Denver's air quality today is in the **Good to Moderate range**, meaning the majority of residents can safely enjoy outdoor activities without concern. Recent reports indicate **no advisories are in effect for ozone or other pollutants** across the Front Range Urban Corridor, which includes Denver, Boulder, and surrounding areas, through this afternoon. The highest ozone AQI recorded last night was 54, which falls within the Moderate category but does not pose a threat for most healthy individuals. Unusually sensitive groups, such as those with preexisting respiratory conditions, may wish to limit prolonged or strenuous outdoor exertion when AQI approaches the Moderate threshold[2].

Current air quality levels have benefitted from **breezy weather and scattered showers**, which help disperse pollutants and keep ozone levels in check. The air quality index fluctuated between 37 and 54 overnight, remaining comfortably below levels that would trigger official health advisories. Over ninety percent of days so far this year have met or exceeded the World Health Organization's safe air quality standards, and the overall risk of health effects remains very low for the general population[1].

Residents can expect **continuing Good to Moderate air quality through the afternoon**, with ozone and particulates well within safe limits. Meteorologists and health officials monitor these readings closely, and updates are available from Colorado's air quality advisory system should conditions change. For most people, today's weather conditions and pollutant levels support routine outdoor activities, whether for exercise or recreation[2][1].

Today in Denver, air quality is generally good with some moderate levels of particulate matter detected early in the morning. As of 1 AM Mountain Standard Time, the ozone Air Quality Index is recorded at 38, which falls into the Good category, indicating the air is clear and safe for most people. The highest particulate matter measurement, specifically PM2.5, reached an index of 56, classified as Moderate. This means air quality is acceptable for the general public, but those who are unusually sensitive, such as people with respiratory conditions, heart disease, older adults, or very young children, should consider reducing prolonged or heavy outdoor exertion during the day.

Pollutants such as carbon monoxide and nitrogen dioxide are predicted to remain in the Good range throughout the day. Overall, ozone concentrations are expected to stay between Good and Moderate, with the only caution for unusually sensitive individuals to limit strenuous activities outdoors between noon and 8 pm. Visibility is expected to be good, though there could be brief periods of reduced visibility during any passing showers or thunderstorms.

No air quality advisories or action days are in effect as of this morning, and there currently are no reports of significant wildfire smoke impacts in Denver. Therefore, outdoor conditions are favorable for most activities, but it remains wise for sensitive individuals to monitor air quality updates and take simple precautions if they notice symptoms when air quality is moderate.

Denver’s air quality today reflects a typical late summer day with manageable pollutant levels and no significant health threats to the broader public. Those planning outdoor exercise or events can do so with confidence, though it’s never a bad idea to check the latest updates if weather or smoke conditions change later in the day. For most, the air in Denver today poses little to no risk, supporting a safe and active Saturday outdoors[1][3][5].

Today, Denver’s air quality is classified as good to moderate, providing a generally comfortable environment for outdoor activities. At 7 AM Mountain Standard Time, the Air Quality Index for particulate matter (PM2.5), a common urban pollutant, was recorded at 44, which falls within the good range and suggests minimal risk to public health. Ozone concentrations are also expected to remain in the good to moderate range throughout the day.

People who are unusually sensitive to ozone, such as those with asthma or other respiratory issues, should consider limiting prolonged or heavy outdoor exertion between noon and 8 pm. Ozone tends to rise during afternoons due to increased sunlight and heat, potentially leading to temporary respiratory discomfort for sensitive individuals. Even during a moderate ozone forecast, it is prudent for at-risk groups to take these precautions.

Other major air pollutants, including carbon monoxide and nitrogen dioxide, are also expected to stay in the good category today. Visibility for the Denver metro area is forecast to be good to moderate, with no significant haze or smoke impacting the region. There are no current advisories issued for ozone or any other pollutant for Denver and the Front Range Urban Corridor until at least 4 p.m., indicating that average residents face low risk from air pollution at this time.

Denver’s air quality trends this August reflect a high proportion of days within safe air quality limits, with historical data showing very low risks of health issues from pollution. However, city officials remind residents that ground-level ozone, while not alarming today, can be a serious health concern on action alert days. Everyone can contribute to better air quality by reducing car trips and emissions, especially during the summer months when ozone levels are most susceptible to spikes.

Monitoring will continue hourly, and advisories may be issued if conditions change due to weather, emissions, or other factors. For now, Denver remains a safe city for outdoor enjoyment, with only mild cautions for those especially sensitive to ozone and airborne particulates[1][3][4].

Denver’s air quality today is in the moderate range for both ozone and fine particulate matter. As of 5 PM yesterday, the Air Quality Index reading for ozone was 58, and for PM2.5 (fine particulate matter) it was 64. Both are classified as moderate, meaning air quality is acceptable, but there might be a minor health concern for people unusually sensitive to pollution. Those individuals, particularly those with heart or lung conditions and older adults, should consider limiting prolonged or heavy outdoor activities.

No air quality advisories or alerts are currently in effect for ozone or other pollutants in the Denver area, and this has been forecast to continue through at least 4 p.m. today. Most other monitored pollutants, including carbon monoxide and nitrogen dioxide, are in the good category, and visibility is considered good to moderate across the Front Range.

Smoke from wildfires in northwestern Colorado is making its way across the region, but conditions in Denver and the Northern Front Range have improved compared to Thursday. On Thursday, there was an action day for multiple pollutants, but air quality has since gotten better, with both ozone and particulate levels decreasing. The improvement is welcome, although anyone sensitive to smoke or pollution should continue to monitor real-time data and take appropriate precautions, such as staying indoors during periods of visible haze or avoiding strenuous outdoor exercise.

Ground-level ozone remains a concern during the summer, as hot temperatures and sunlight can increase its production. Even moderate levels can cause acute respiratory symptoms, trigger asthma attacks, and aggravate chronic lung conditions, especially in children, older adults, and those with pre-existing respiratory issues.

Overall, Denver’s air is healthier than earlier in the week, but moderate levels of ozone and particulate matter call for a bit of caution for those who are unusually sensitive to air pollution.

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.

Air quality and advisory updates are available from the Colorado Department of Public Health and Environment and can be checked online for the latest information throughout the day[1][2][4].

Denver’s air quality today is classified as Moderate, based on measurements and forecasts for ozone and particulate matter in the region. The latest data show the highest Ozone Air Quality Index, or AQI, reached 93 in the evening hours of July 25th, indicating moderate ozone pollution. Meanwhile, the AQI for fine particulate matter, known as PM2.5, was 55, also within the moderate range.

Moderate air quality means the air is generally acceptable, but there may be a risk for some people. Sensitive groups—such as children, older adults, and those with respiratory conditions like asthma—should consider limiting prolonged or heavy outdoor activity, especially from noon to 8 pm. In these conditions, active children, healthy adults, and anyone with lung or heart diseases may experience mild symptoms or worsening of preexisting conditions. Air quality authorities have issued an Ozone Action Day Alert, encouraging all residents to avoid rigorous outdoor activities during the heat of the day.

For fine particulate matter, unusually sensitive individuals are advised to reduce extended outdoor exertion, though most people will not be affected. Carbon monoxide and nitrogen dioxide levels are both in the Good category and not expected to pose any health risks today.

Visibility in Denver is expected to be moderate. The main health concern for the day remains ground-level ozone, which is formed from vehicle emissions and industrial pollution reacting with sunlight. Exposure to elevated ozone levels may cause acute respiratory effects, trigger asthma attacks, and potentially cause lasting lung damage with prolonged high exposure.

In summary, Denver residents are advised to stay informed and follow health recommendations, particularly if they are part of a sensitive group. For the general population, outdoor activities are safe but avoiding peak afternoon hours is recommended for those at higher risk. The air pollution risk today is moderate, and most people will not experience symptoms, but precautions are suggested for those unusually sensitive or with underlying health issues. The Ozone Action Day Alert for the Front Range will remain in effect until at least this afternoon to ensure public health guidance is followed.

Denver’s air quality today is classified as Good to Moderate, with no active advisories for ozone or other pollutants in effect through at least 4 p.m. for the entire Front Range Urban Corridor, which includes the Denver-Boulder area. The latest assessment by the Colorado Department of Public Health and Environment notes that unsettled weather and scattered showers are helping to limit ozone formation. As a result, ozone concentrations are expected to remain in the Good to Moderate range for the day.

The Air Quality Index for Denver today generally falls between 51 and 100, which corresponds to a Moderate level. This means air quality is acceptable, though there may be a risk for individuals unusually sensitive to air pollution. Key contributors to air quality at this time include ozone and fine particles (PM2.5), but levels are not expected to pose a concern for the general public.

Current visibility in Denver is described as moderate. No Ozone Action Day is in effect, and no additional pollutants have reached levels that would trigger health advisories. If atmospheric conditions change and ground-level ozone or other pollutants increase, an advisory will be issued, but as of this morning, the air remains clear of such alerts.

Weather forecasts indicate continued scattered showers, which should continue suppressing pollutant buildup and maintain stable air quality through the afternoon. Residents and visitors can engage in regular outdoor activities with minimal concern for health impacts, but anyone with heightened sensitivity to air pollution should consider monitoring any updates if atmospheric conditions change later in the day. Real-time data and updates remain available through state air quality resources and monitoring stations for those seeking more detailed information throughout the day[1][4][2].

Denver is under an Ozone Action Day Alert that began Friday afternoon and remains in effect until at least 4 p.m. Saturday, July 12, 2025. This alert covers the entire Front Range Urban Corridor, including Denver, Boulder, Fort Collins, and Greeley. Recent measurements show that ozone levels have climbed into the Unhealthy for Sensitive Groups category, with an Air Quality Index of 104 recorded Friday evening. This means that while the general public isn’t likely to be affected, people with respiratory conditions, children, older adults, and those who are unusually sensitive to air pollution should limit prolonged or heavy outdoor exertion.

Particulate matter, or PM2.5, has also been measured at moderate levels, with an AQI of 54. For most people, air quality remains acceptable; however, sensitive individuals might experience mild respiratory symptoms and should consider reducing outdoor activities, especially if they have underlying heart or lung disease.

Unsettled weather earlier in the week kept ozone concentrations in the Good to Moderate range, but hot and stagnant conditions are now allowing ozone to build up. Action Days like today are called when air pollution is either already unhealthy or is likely to worsen. This triggers voluntary pollution prevention measures and public health recommendations.

If you see or smell smoke, especially from wildfires in southwestern Colorado, remain indoors and keep windows closed, particularly if you are sensitive to air pollution. The Colorado Department of Public Health and Environment advises everyone, but especially vulnerable groups, to monitor symptoms and avoid unnecessary exposure during periods of higher pollution.

For most Denver residents, outdoor activities are still safe, but it is recommended to stay informed on hourly updates and advisories as conditions can change quickly. Those in sensitive groups should pay particular attention and adjust outdoor plans accordingly to minimize health risks.

Denver’s air quality for Sunday, July 6, 2025, is being rated as moderate for particulate matter (PM2.5) with an Air Quality Index (AQI) of 57, based on the latest official observations. This means that the air is generally acceptable for most people, but individuals who are unusually sensitive to air pollution, particularly those with respiratory or heart conditions and older adults, could begin to experience mild health symptoms. Those in sensitive groups are advised to consider reducing prolonged or heavy outdoor exertion during the day[1].

Ozone concentrations for today are projected to remain in the good to moderate range, particularly between noon and 8 p.m. People who are unusually sensitive to ozone should also consider limiting outdoor activity during these hours[1]. Ozone can be particularly troubling during warmer periods and may cause acute respiratory issues or trigger asthma attacks in sensitive individuals.

Other common pollutants such as carbon monoxide and nitrogen dioxide are expected to stay in the good category, presenting minimal risk to the general population. Visibility throughout the day is forecast to be good to moderate, which aligns with the moderate levels of particulate matter being detected[1].

No air quality advisories or Ozone Action Day Alerts are currently in effect for the Denver metro area or the greater Front Range Urban Corridor. Residents can continue normal activities but should remain mindful of symptoms if they fall into sensitive categories[1][3].

Denver’s air quality has seen challenges in the past, particularly during hot, stagnant days when pollution can become trapped near the surface, intensifying ozone and particulate concentrations. While today’s levels are moderate and do not warrant a formal advisory, the city’s long-term air quality can fluctuate quickly due to weather shifts and population pressures, making it important for residents to stay informed through official updates[1][4].

Denver’s air quality for today, July 5, 2025, is generally favorable, with no official advisories in effect for ozone or any other major pollutant in the Denver-Boulder area or the surrounding Front Range Urban Corridor until at least 4 p.m. The Air Quality Index for fine particulate matter, known as PM2.5, was recorded at 55 earlier this morning, which falls in the moderate range. For most people, this means the air quality is acceptable, but some individuals who are unusually sensitive may experience mild respiratory symptoms. Those with heart or lung diseases, older adults, and especially sensitive people are advised to consider reducing prolonged or heavy outdoor exertion.

Ozone concentrations are expected to stay in the good to moderate range throughout the day. While this indicates generally clean air for the majority of residents, people who are particularly sensitive to ozone should minimize outdoor activity, especially from noon until 10 p.m. when concentrations tend to be higher. Ground-level ozone, formed when pollutants from vehicles and industrial sources react in sunlight, can cause breathing discomfort and trigger asthma, so it’s prudent for at-risk groups to be cautious during the warmest parts of the afternoon.

Other major pollutants, including carbon monoxide and nitrogen dioxide, are forecasted to remain in the good range. Visibility in the area is also expected to be between good and moderate through the day, suggesting that hazy conditions will be minimal. Officials note that ground-level ozone is a persistent air quality concern along the Front Range each summer. Even without an active advisory, individuals with respiratory sensitivities should stay alert to changing conditions, especially during outdoor activities in the heat of the day. For most residents and visitors, today’s conditions support regular outdoor activities with only minor precautions needed for those who are unusually sensitive to air pollution[1].
