About the Hourly Air Quality Forecasts
These forecasts are based on the Environmental Protection Agency (EPA)'s AQI federal health standards. The AQI Forecast lets the public know expected air quality conditions and provides advice about what they can do to protect their health, especially that of children, seniors and people with respiratory problems.
Forecasts are also available on the Air Arizona mobile app | View >
ADEQ also issues a:
-
High Pollution Watch (HPW) when there is the potential for a pollutant to exceed the federal health standard
-
High Pollution Advisory (HPA) when it is imminent or there is a high probability for a pollutant to exceed the federal health standard

Air Quality Risk-Based (AQR) Lead Forecast
ADEQ Lead (PB) forecast for:
- Hayden Area | View Forecast >
ADEQ studied historical weather patterns as they relate to lead air pollution to develop three lead risk categories – low, moderate and high. The risk-based lead forecast for Hayden predicts the possibility of reduced air quality due to lead. ADEQ monitors for air lead levels in Hayden according to EPA’s requirements (one sample every six days). These samples are analyzed by a certified laboratory and take one month to process. These results are used to refine future lead forecasts.
