Current Air Quality & Forecast
Air Quality Forecast
September 25 – September 29: Expect a cooling trend beginning Friday as low-pressure swings into the PNW and portions of Northern California. Immediately after the initial low, a second trough will swing further south and provide additional cooling to the Central Coast. Do not expect too much in the way of moisture as global ensembles indicate drier mid-latitudinal wind flow. Behind the second low, building high-pressure will resume and return temperatures to seasonal levels by Tuesday. Temperatures will range from the low-50s to the high-70s at the coast and low-50s to low-90s inland. Due to below seasonal temperatures inland, ozone production will be at normal levels; therefore, ozone AQIs will remain GOOD. As low-pressure influences conditions, expect an increase in atmospheric mixing. As a result, PM2.5 (smoke) AQIs will remain GOOD. By mid-week next week as high-pressure builds, expect MODERATE AQIs as atmospheric mixing decreases. 20 mph wind speeds with up to 30 mph gusts in the Salinas Valley could bring PM10 (dust) AQIs to MODERATE. However, moisture from a robust marine layer will more than likely keep PM10 AQIs to a minimum.
