Air Quality Forecast

January 20 – January 23: Weather conditions will be dry, pleasant and seasonal this week with a mix of sunny and partly cloudy days. Temperatures will consistently range between upper 40s to low 60 for most of the region, but certain areas in the Ventana Wilderness and along Highway 101 will peek into the 70s. Although there’s a near-zero chance of precipitation, relative humidity will remain between 80-100% in Santa Cruz and northern Monterey County. Winds will be calm this week and gusts will only reach 10 mph at most. Therefore, PM10 (dust) AQI will remain GOOD. However, the stable atmosphere will do little to aide with ventilation so PM2.5 (smoke) AQIs may reach MODERATE. Ozone levels should remain below State standards and therefore ozone AQIs will remain GOOD.
