With continuing smoke from the Camp Fire (and any other Northern CA fires), the EPA has a small scale air quality map of the greater Bay Area. The Bay Area air quality district (BAAQMD) provides a table, updated hourly, of estimated air quality for a number of specific locations.

The critical concern is small particles which make up the smoke by the time it gets here (larger ones fall out closer to the source). They're many times smaller than the width of a human hair. They find their way deep into our lungs and into our blood stream. Air quality and health folks recommend against vigorous activity and advise staying indoors as much as is practical.
