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 26 ?Çô March 1: On Monday expect cool temperatures and scattered light showers in the afternoon/evening with rain totals generally under 1/10th of an inch, followed by breezy northwest winds. Beginning Tuesday a high-pressure system will bring dry conditions and more cool temperatures. Late this week and into the weekend expect unsettled weather as a stronger storm system slowly moves south into our region from the Gulf of Alaska. Temperatures this week: mid 40s to low 60s at the coast and upper 30s to upper 60s inland. Cool temperatures will keep afternoon ozone levels below State standards and thus air quality for ozone will be GOOD. The high-pressure system midweek may reduce air mixing, meaning AQIs for PM2.5 (smoke) should be generally GOOD but likely MODERATE in the San Lorenzo Valley, and PM10 (dust) will be GOOD.
