What affects air quality in Phoenix
Maricopa County identifies construction, vacant lots, dirt roads and tracked-out soil as dust sources, and says winter wood burning is a recurring PM2.5 source in greater Phoenix.
This is county and greater-Phoenix source context, not a statement that dust or wood smoke is affecting Phoenix now.
Local monitoring and context
Maricopa County's ambient monitoring network samples pollution in varied settings and uses representative sites because monitoring every location in and around Phoenix is not feasible.
County monitors are representative samples with differing objectives; no one site is treated as all of Phoenix or as this page's current-data source.
City air quality FAQ
How should I read the AQI for Phoenix?
US AQI condenses air quality into one value. On this page, it helps you quickly judge whether conditions look good, moderate or more polluted than usual.
Is the air quality good for going outside?
Check the outdoor and running cards first. They combine AQI, particles, ozone, weather and other factors that can affect outdoor comfort.
Should I ventilate right now?
The ventilation card considers AQI and pollutants such as particles, nitrogen dioxide and ozone. If values are elevated, a shorter opening or a later moment may be better.
Why can air quality change during the day?
Weather, emissions, ozone formation, particles and air flow can shift local conditions, so the next hours can differ from the current reading.

Current data
This page uses US AQI.
The displayed values are a clearly marked sample fallback, not current provider data or an official local measurement.
Sample data is shown because current data is unavailable. The sample values are not Open-Meteo or CAMS data and should not be used as current air quality information.
