About Air Quality in Arizona
Arizona's air quality is shaped by its desert environment, rapid population growth, and seasonal patterns. Phoenix and Tucson metro areas face challenges with ozone, particulate matter from dust storms, and vehicle emissions. The state's intense sunlight accelerates ozone formation during hot months.
We monitor air quality across 4 major cities in Arizona using real-time data from the EPA's AirNow network. The best air quality is currently in Mesa with an AQI of 36. The area requiring most attention is Phoenix with an AQI of 64.
Primary Pollution Sources in Arizona
- Vehicle emissions in growing metro areas
- Dust storms (haboobs) and windblown dust
- Construction activity
- Wildfires and prescribed burns
- Mining operations
- Interstate transport from Mexico and California
Seasonal Air Quality Patterns
Summer brings the highest ozone levels due to intense heat and sunlight. Monsoon season can bring haboobs that dramatically worsen particulate matter levels. Winter generally has better air quality. Wildfire impacts typically occur in spring through early summer.
Health Impacts
Phoenix residents face significant air quality challenges during summer. Dust storms create acute respiratory risks for all residents. The state's growing population of retirees is particularly vulnerable to heat-exacerbated air quality impacts.
Recommendations for Arizona Residents
Arizona residents should limit outdoor activity during summer afternoons when ozone peaks. Stay indoors during dust storms with windows and doors sealed. Have respiratory protection available. Monitor air quality closely during monsoon season when haboobs are possible.
