Air Quality Forecast

June 1 – June 5: Conditions throughout the North Central Coast Air Basin will feature persistent onshore winds around 5-12 mph and periodic gusts reaching up to 20 mph. There will be a slight cooling trend midweek, but temperatures will remain seasonal. The diurnal marine layer fog will help keep coastal highs in the 50s and it will reach into the upper 70s to mid-80s further inland. Lows across the region will be in the 50s. Residual moisture from a recent low-pressure system remains in the region, but chances of precipitation are low at around 0-5% on most days. The coast may see light overnight drizzle, if any. Atmospheric conditions indicate PM2.5 (smoke) AQIs should remain GOOD, but smoke impacts from active wildfires around the state may elevate PM2.5 AQIs to MODERATE later in week. Stable conditions will help keep PM10 (dust) AQIs at GOOD. Ozone levels should remain below State standards and therefore ozone AQIs will remain GOOD.
