AirNow is your one-stop source for air quality data. Our recently redesigned site highlights air quality in your local area first, while still providing air quality information at state, national, and world views.

Smoke from several wildfires in the Los Angeles, California area is affecting air quality in portions of the state. Check the AirNow Fire and Smoke Map for local air quality conditions, fire locations and smoke plumes.

The AirNow system automatically generates this list every hour, based on the areas with the highest NowCast AQI for ozone or particle pollution. Because air quality can change during the day, the areas on this list may change throughout the day, too.

This map shows fine particle pollution from wildfires and other sources. It does not show air toxics or other pollutants. For ozone, go to AirNow .

Click LEGEND to display the AQI legend. "No data" means nothing was reported for the most recent hour. Click BASEMAP to choose a different background map. Refresh your screen periodically to see the most recent data. The map opens in a new tab. To go back, click on the AirNow tab or the AirNow logo.
