when will bay area air quality improve

The Bay Area air quality is currently impacted by wildfire smoke, specifically from the Pickett Fire in Napa County, with effects expected through Wednesday, August 27, 2025. The Air Quality Management District has extended an air quality advisory through that date due to this smoke, indicating that the air quality is likely to improve once the wildfire smoke clears after Wednesday. In general, the Bay Area has made significant progress in improving air quality over the past decades due to cleaner transportation, stricter regulations, and climate policies, and the longer-term trend is toward improvement. However, short-term air quality fluctuations, especially related to wildfire smoke and seasonal weather patterns, still occur. For the immediate forecast, residents can expect moderate air quality conditions due to wildfire smoke but should see improvement starting after August 27, 2025, as the smoke impact is expected to lessen then.
