Air Quality Forecast

August 7 – August 11: High pressure over the weekend will keep things warm for the Central Coast with inland areas receiving HEAT ADVISORIES though 8/9.  At the coast, expect the usual buildup of early morning marine stratus that should help moderate temperatures. Beginning on Monday, low-pressure moving in off the coast should cool things down a bit. Temperatures will range from the mid-50s to the mid-70s at the coast and low-60s to high-100s inland. Despite elevated temperatures inland, ozone production will be at normal levels; therefore, ozone AQIs will remain GOOD.  20 mph wind speeds with 30 mph gusts in the Salinas Valley along with dry conditions could bring PM10 AQIs to MODERATE.  As high pressure remains over the region, atmospheric stagnation will promote the accumulation of PM2.5 (smoke) thus PM2.5 AQIs may become MODERATE.  Additionally, smoke from wildfires in Northern California and the PNW could be transported to the Central Coast. However, as long as southwesterly flow is maintained, the smoke should be transported away from the region.
