The air quality in San Francisco is officially the worst that it’s ever been. 

Friday afternoon, San Francisco’s air quality index hit 271. That’s the highest AQI ever recorded in the city. 

Most of the Bay Area is under code Purple, which means “very unhealthy.” 

Residents are urged to stay indoors and avoid any outdoor activities. If you must go outside, it’s advised to wear a respirator mask.

It’s been over a week now that the Bay Area is experiencing these unhealthy air quality conditions due to smoke from the Camp Fire in Butte County. 

Many schools are closed and events canceled due to the hazardous conditions. 

Pets are also encouraged to stay indoors until the air quality gets better. 

Right now, it’s predicted that air quality issues will persist until the day before Thanksgiving.
