Air Quality Forecast

April 14 – April 18: Monday morning begins with a marine layer of about 1500 feet extending into the Salinas Valley, clearing into a beautiful afternoon. Tuesday morning’s marine layer should be only 500 feet deep and therefore less extensive. The minor heat risk of Monday and Tuesday (highs in the upper 60’s at the coast and upper 80’s inland) will reverse to cooler than normal temperatures late this week (highs in the upper 50’s at the coast and the mid-60’s inland). Expect gusty winds and the possibility of rain on Friday. The short-lived minor heat risk early this week will not raise ozone levels above State standards, therefore ozone AQIs will remain GOOD. The AQI for PM2.5 (smoke) will vary between GOOD and MODERATE. Relatively calm conditions will keep AQI for PM10 (dust) GOOD.
