In the SF Bay Area, there are a lot of parts (like the entire South Bay) that have frequent inversions and usually no off-shore breezes, due to the coastal mountains. In fact we've had a big run of bad air quality days.
With a few of the recent fires to the north of SF we've also had the charming situation in the South Bay of ocean breezes blowing the smoke from the fires over us... it was blowing down the cost offshore of SF, and then inland.

- annywhey 8y agoWe've had runs spanning a week plus this season where the AQI never gets under 50...SF is not really safe when it's wildfire smoke from the north because it ends up recirculating. In fact we're in that kind of scenario right this minute.
