Air Quality Forecast

July 7 – July 11: Cooler, slightly below normal temperatures may be expected in beginning of the week. Temperatures across the interior will only reach the mid 70s and 80s while coastal areas will see upper 50s to 60s. A warming trend is on track to begin Wednesday with most sites to see near seasonal temperatures as highs warm back into the 80s across most of the interior. Although winds will be light and onshore, localized fire weather concerns will be elevated as potential fuels dry out with warmer temperatures, particularly above the marine layer. Ozone levels should remain below State standards, and ozone AQIs should remain GOOD. As conditions remain dry and calm, expect PM10 (dust) AQIs to be GOOD to MODERATE. Although the Madre Fire is presently burning to the south in San Luis Obispo County, the northwesterly winds should help dissipate PM2.5 wildfire smoke out of the area resulting in GOOD to MODERATE AQIs.
