Current Air Quality & Forecast
Air Quality Forecast
January 6 – January 9: Light to moderate rain will continue to fall throughout the region into Tuesday evening, but the rest of this week will be dry as a cut-off low is replaced by a high-pressure system on Wednesday. However, the grey overcast and cool weather will persist. Temperatures will range from the low-40s to upper 50s in areas along the Monterey Bay coast, and a little warmer as highs reach the mid-60s a little further inland. A Cold Weather Advisory has been issued for Thursday evening because temperatures are expected to drop into the 30s. Winds are expected to be mostly calm at a steady 2-6 mph and gusts of only 10-14 mph in most areas. The light breezes and moisture should help keep PM10 (dust) AQIs at GOOD. The impending high pressure may stabilize atmospheric conditions later in the week, reducing ventilation of woodsmoke in the San Lorenzo Valley and other valleys in the region. Therefore, PM2.5 (smoke) AQIs may be elevated to MODERATE. Ozone levels should also remain below State standards, and therefore ozone AQIs will remain GOOD.
