Air Quality Forecast

January 13 – January 16: Seasonally warmer days expected this week due to high pressure stalling over the region. Temperatures will be 8-15 degrees above average for the Central Coast with highs approaching 70 degrees on the coast and mid-70s in communities along the Hwy 101 corridor. Lows will be in the mid-40s in most areas, but  evening temperatures around Big Sur and Ventana will only drop into the mid to upper 50s. Winds will mostly be a gentle offshore flow with gusts topping out at 10 mph. PM2.5 (smoke) AQIs may reach MODERATE, particularly in the San Lorenzo Valley, due to a stable atmosphere, light ventilation, and increased woodsmoke. Calm winds should help maintain PM10 (dust) AQIs at GOOD. Ozone levels should remain below State standards and therefore ozone AQIs will remain GOOD.
