Air Quality Forecast

 

September 9 – September 13: The low-pressure system continues the recent cooling trend, with inland high temperatures generally in the upper 80s to mid 90s, southern Monterey County and San Benito County approaching 100 degrees, and coastal high temperatures ranging 60s to 70s. The marine layer will continue to deepen early this week, with stratus clouds extending into the inland valleys. Beginning Tuesday, as a deeper low-pressure system approaches, temperatures will drop further to seasonal averages, with gusty winds up to 20-30 mph in the gaps and passes. The cooling trend will help keep ozone air quality GOOD. Air quality for PM2.5 (smoke) will vary between GOOD and MODERATE depending on regional fire activity, and PM10 (dust) should be GOOD with periods of MODERATE in the southern Salinas valley.
