Air Quality Forecast

For September 18-23: This weekend will heat up again, but with less hours of sun in September, little smog is expected to form and air quality should remain mostly GOOD. Smog season has officially "sunset" for the year. Could still see some MODERATE air quality at times due to residual wildfire smoke coming up from Oregon. Erik Saganic, Agency Forecaster
