Air Quality Forecast

October 26 – October 30: An ongoing upper-level troughing pattern will sustain unseasonably cool conditions and high atmospheric mixing across the North Central Coast Air Basin this week. Daytime temperatures are expected to reach the upper 50s to lower 60s along the coast and the mid-60s to lower 70s further inland, while nighttime lows will dip into the upper 40s to lower 50s. There’s a moderate chance of rain Friday and going into the weekend, but chance of precipitation during the week is below 10%. Onshore north to northwesterly breezes will average between 5 and 14 mph, though localized afternoon gusts may exceed 25 mph along the Big Sur Coast and southern Monterey County. Good atmospheric mixing should keep PM2.5 (smoke) AQIs at GOOD while the cool, moist onshore airflow will trap airborne dust particles and help keep PM10 AQIs at GOOD despite breezy conditions. Ozone production will be normal and within State standards. Therefore, ozone AQIs should remain GOOD.
