Today’s Air Quality & Forecasts

Current Air Quality Conditions

Current air quality values and colors correspond with the Air Quality Index (AQI). More information about the AQI is available at the bottom of this webpage.

The grid below shows current AQI conditions for each pollutant that is measured at each of our monitoring stations. By clicking the “Show” button on each monitoring station box, you can see what the AQI conditions were for the past 24 hours, shown in a rolling format.

note: values with * indicate last known reading.

Forecasts

Forecasted air quality values and colors correspond with the Air Quality Index (AQI). More information about the AQI is available at the bottom of this webpage.

EPA AirNow Fire and Smoke Map

The EPA has launched the AirNow Fire and Smoke Map that is designed to provide the public with additional information on levels of fine particle pollution in the air, particularly during wildfires. The Fire and Smoke Map displays AQI data from permanent monitors, temporary monitors, and low-cost sensors.

For additional information about California wildfires and potential smoke impacts, please see the California Smoke Information site.

Historical Data

To check “AQI Summary by Date”, click the link above which will direct you to EPA’s AirNow website. Select the “Archive” header on the new webpage. Then, use the calendar tool at the bottom of the webpage to select the historical date. On the left side of the screen, there are options to focus on specific pollutants using both the “Contours” and “Monitors” layers.

About AQI Values & Recommendations

See the AQI Table below for how to interpret the AQI colors shown in the current air quality grid and forecasts above. The index numbers represent a relative ranking for the pollutant, not the measurement of a pollutant. To see the actual measured concentrations of the pollutant, visit the Station Data webpage. The Index below presents ratings for: ozone; particulate matter smaller than 10 microns in diameter (PM10); and particulate matter smaller than 2.5 microns in diameter (PM2.5).
