Outdoor
Current values look suitable for ordinary outdoor activity for most people.
Why: Air quality looks good, but the UV index is high, so sun protection may be useful during longer outdoor time.
Austin, Texas, United States
Current values look suitable for ordinary outdoor activity for most people.
Current values look suitable for ordinary outdoor activity for most people.
Why: Air quality looks good, but the UV index is high, so sun protection may be useful during longer outdoor time.
Current values look suitable for an easy outdoor run.
Why: Air quality supports running, but a high UV index makes sun protection useful for longer runs.
Current values support brief ventilation.
Why: Low AQI and low pollutant levels support brief ventilation.

The City of Austin says its Air Quality Program works with regional partners through Air Central Texas, and explains that warm, sunny days with light winds can contribute to ground-level ozone formation in the Austin region.
This is evergreen regional coordination and ozone-formation context, not a current AQI reading, forecast, regulatory classification, source ranking, neighborhood-level condition, or this site's current-data provenance.
TCEQ's 2025 five-year assessment documents active Austin-area air-monitoring sites and says Central Texas ozone monitors provide near-real-time public data while measuring maximum concentrations in populated areas and concentrations upwind of urban areas for regional-transport evaluation.
This describes official regional monitoring-network purposes and public-data context; individual sites and parameters can change, the City is not claimed to operate them, and TCEQ monitoring is not this site's current Open-Meteo/CAMS data provider.
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.
Check the outdoor and running cards first. They combine AQI, particles, ozone, weather and other factors that can affect outdoor comfort.
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.
Weather, emissions, ozone formation, particles and air flow can shift local conditions, so the next hours can differ from the current reading.
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.
Each local statement is linked to a checked primary-authority source. A source check is editorial provenance and does not describe current-data freshness.
Local sources support the background claims below; they are not the source of the current data shown above unless explicitly stated otherwise.

The page says Austin's Air Quality Program coordinates with regional partners through CAPCOG's Air Central Texas initiative and that warm, sunny days with light winds contribute to ground-level ozone formation.
Applicability: Official city material supports regional-program coordination and weather-related ozone-formation context, not current conditions, a fixed number of ozone-action days, regulatory status, source ranking or this site's current-data provenance.
Based on this source: The City of Austin says its Air Quality Program works with regional partners through Air Central Texas, and explains that warm, sunny days with light winds can contribute to ground-level ozone formation in the Austin region.
Texas Commission on Environmental Quality
The Central Texas section and Austin-area active-sites figure document Austin-area monitoring sites and describe ozone monitors as providing near-real-time public data for populated-area maxima and upwind regional-transport evaluation.
Applicability: Official five-year assessment supports Austin-area site and Central Texas ozone-network context; it does not make one monitor citywide, assign operation to the City, or supply this site's current conditions.
