Air Quality Index Information

The above map reflects the most recent Air Quality Index (AQI) for today at each of the air monitoring stations. Station data is refreshed at the top of every hour, but may not be shown immediately due to data transfer and verification limitations. The AQI represents a weighted rolling average concentration over 24 hours for PM10 and PM2.5; and 8 hours for Ozone.

February 20 - February 24: The chance of lingering showers on Tuesday increases in the late afternoon/evening and tapers off Wednesday. We will have a dry spell mid- to late-week and then beneficial rain this weekend. Temperatures will range from the mid 40s to low 60s at the coast and from the low 40s to upper 60s inland. Cool temperatures keep afternoon ozone levels below State standards and thus air quality for ozone will be GOOD. Low pressure and light winds should make for good ventilation and therefore AQIs for PM2.5 (smoke) and PM10 (dust) will also be GOOD.
