Today’s air quality in the Bay Area is significantly better than it has been for the last couple of weeks. This is PurpleAir’s map with the AQ&U conversion applied.
San Francisco is looking particularly good (well “moderate” according to the tables.) Except for people with underlying health issues, the SF air should be breathable. It gets a bit worse as you travel down the Peninsula to the South Bay where it gets into unhealthy for sensitive groups, and it’s even worse further south around Santa Cruz where it’s unhealthy for everyone.
Nevertheless, the winds have been in our favor and the air is much better than it has been in recent days and weeks.
