Current Air Quality & Forecast
Air Quality Forecast
March 16 – March 20: A strong high-pressure ridge is continuing to build just off the coast, and it will bring record breaking heat to the region by Tuesday. High temperatures will climb well into the 90s for all areas away from the coast. The marine layer will keep temperatures a little cooler with low and high temperatures in the range of 50-80 degrees. An offshore flow and heavier winds will die down by Tuesday to just 1-4 mph as the high pressure settles in. Gusts will vary between 7-10 mph. The stable atmosphere and calm winds will help keep PM10 (dust) AQIs at good, but reduced ventilation may increase PM2.5 (smoke) AQIs to MODERATE-UNHEALTHY FOR SENSITIVE GROUPS, particularly in the San Lorenzo Valley and other communities where wood smoke from home heating tends to accumulate overnight. Ozone levels should remain below State standards and therefore ozone AQIs will remain GOOD.
