Air Quality Forecast

November 24 – November 28: High pressure will bring favorable conditions to the region this week. Temperatures will range from low 50s to mid-60s along the coast while inland areas in the southern parts of Monterey and San Benito Counties will see highs reaching into the upper 60s or even low 70s. Wednesday and Thursday (Happy Thanksgiving) are expected to be warmest days, and temperatures will begin to cool going into the weekend as another system moves in. As for winds, expect gentle onshore flows for most of the week and shift to gustier offshore winds at the weekend. Low level clouds or fog will blanket much of the forecast area each evening but will mix out by the late morning. Ozone levels should remain below State standards, therefore ozone AQIs will remain GOOD. Calm winds should help PM10 (dust) remain GOOD. Reduced ventilation and increased smoke impacts from home heating may raise PM2.5 (smoke) AQIs to MODERATE.
