Current Air Quality & Forecast
Air Quality Forecast
March 30 – April 3: Cooler temperatures and light rain is expected this week. Temperatures will range from the low to mid 40s up to the mid-60s throughout the forecast area. Winds will be mostly calm with gusts of only 9-12 mph but may increase to gusts of around 20 mph as a low-pressure system moves in on Tuesday. There’s a slight chance of rain on Tuesday evening, but Wednesday going into Thursday is more likely. Only between 0.25” - .5” of precipitation is expected, and it will mostly be concentrated along the Big Sur coast and in the Santa Cruz mountains. The lower pressure system and unstable atmosphere will help ventilation and keep PM2.5 (smoke) AQIs at GOOD in most areas, but it may reach MODERATE-UNHEALTHY FOR SENSITIVE GROUPS in the San Lorenzo Valley and other communities where wood smoke from home heating tends to accumulate overnight. Calm winds and moist conditions will help keep PM10 (dust) AQIs at GOOD. Ozone levels should remain below State standards and therefore ozone AQIs will remain GOOD.
