Practical guidance

Outdoor

Outdoor activity is generally possible, but conditions are not ideal.

Why: AQI or pollutant levels are elevated, so this guidance is more cautious.

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

Ventilate briefly and check conditions again later.

Why: AQI or pollutant levels are elevated, so longer ventilation may be better later.

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.
