Phoenix is experiencing moderate air quality today, with specific pollutants reaching levels that may be of concern for sensitive groups. Ozone levels have reached an AQI of 101, which is categorized as "Unhealthy for Sensitive Groups." This means that people with respiratory issues, children, older adults, and those who are active outdoors should limit prolonged exertion outside today. The maximum 8-hour average ozone concentration stands at 71 parts per billion.
Particulate matter is also being closely monitored. PM10, or larger dust particles, is at an AQI of 58, considered moderate, and PM2.5, which refers to fine particles, is at 39, which is in the good range for most of the population. Both types of particulate pollution can irritate the respiratory system and worsen chronic heart or lung diseases, but the current levels are not expected to affect the general population.
Earlier this year, Phoenix was named the fourth most ozone-polluted city in the United States, according to the American Lung Association’s 2025 State of the Air report. This ranking reflects ongoing concerns about ground-level ozone, or smog, which can trigger asthma attacks and other serious health issues, especially for those in vulnerable groups. The wider Phoenix area continues to experience short-term spikes in both ozone and particle pollution throughout the year.
Today’s air quality indicates that most residents can continue normal activities, but those unusually sensitive to air pollution should take precautions, especially during peak afternoon hours when ozone concentrations are typically highest. Staying informed about local air quality levels can help the community manage health risks while enjoying outdoor life in the Valley of the Sun. For the most current updates, residents are encouraged to monitor local air quality resources provided by state environmental agencies[1][3][5].
