Current Air Quality & Forecast

 

Air Quality Forecast

 

May 9 – May 13: As a high-pressure ridge sets up, expect a warm and dry trend likely through mid-May. Temperatures will peak Friday, with highs at the coast in the low-70s and inland in the low-90s. The National Weather Service has issued a minor Heat Advisory for inland areas. Winds will move offshore and begin to dry out vegetation. The current level of fuel moisture is above average, however, and likely to keep fire weather concerns low. Once the offshore wind pattern ends this weekend, we will experience the typical summer pattern of coastal stratus in the evening/early mornings. Ozone air quality levels should remain GOOD despite the warmup. Breezy conditions will keep air well mixed, so AQIs for PM2.5 (smoke) will be generally GOOD with occasional periods of MODERATE readings in the valleys during late-night/early-morning hours. The AQI for PM10 (dust) should also remain GOOD.
