Outdoor
Outdoor activity is generally possible, but conditions are not ideal.
Why: AQI or pollutant levels are elevated, so this guidance is more cautious.

Practical guidance
Running
Outdoor running is generally fine. If you are sensitive to air pollution, consider keeping the effort easy.
Why: Air quality indicators are elevated, so the running guidance is more cautious.
Ventilation
Consider waiting before longer ventilation.
Why: PM2.5, PM10, NO2 or ozone is elevated, so longer ventilation may bring more outdoor pollution indoors.

What affects air quality in Dallas
TCEQ's Dallas-Fort Worth inventory says mobile sources dominate regional carbon-monoxide emissions, while area, on-road and non-road sources are the main regional NOx contributors.
This is a DFW regional inventory summary, not a current Dallas reading or a neighborhood-level source assignment.
Local monitoring and context
TCEQ's site directory lists multiple Dallas monitors, including Dallas North No. 2, Dallas Executive Airport, Dallas LBJ Freeway, Dallas Bexar Street and Dallas Elm Fork.
The directory records distinct sites and operators; it does not make one station representative of all Dallas or source this page's current AQI.
City air quality FAQ
How should I read the AQI for Dallas?
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.
Current and hourly air-quality values are CAMS-based model estimates, not measurements from a local monitoring station. They may not reflect street-level conditions.
