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.

Sept 22-25 After a brief cool down, the next few days will see a return to warmer conditions followed by a couple more days of cooler temperatures. A low pressure trough moves in from the NW bringing a marine layer along the coast, which will keep the warmer temperatures along the coast moderate while inland temperatures will increase for the remainder of the week. Coastal temperatures will be in the mid 60s-70s while inland areas will range from low 80s to upper 90s. Overnight lows in the 50s along the coast and low 60s inland. AQIs for PM2.5, PM10 and OZONE are expected to be GOOD overall. However, Salinas Valley and Hollister may see MODERATE conditions during periods of afternoon gusts and AQI for Ozone may bump up to MODERATE in the inland areas during afternoon peak temperatures.
