Bay Area Issues Air Quality Advisory as Oregon Wildfire Smoke Reaches San Francisco

Officials say onshore flow pulled smoke from Oregon’s Moon Complex into the marine layer over San Francisco.

A smoky haze blankets San Francisco in 2023. People are reporting smoke smells in the city as Oregon wildfires burn.
Wildfire smoke contains tiny particles and other pollutants that are unhealthy even for short exposure.

Overview

  • The Bay Area Air District issued the advisory Saturday evening and said smoky conditions were likely to continue through Sunday.
  • Residents reported hazy skies and a chemical smoke smell in several San Francisco neighborhoods, and PurpleAir readings topped 100 Saturday night.
  • Health guidance urges older adults, children and people with respiratory conditions to limit outdoor exposure, keep windows closed and use recirculated air in cars.
  • The Moon Complex in southwest Oregon, ignited by lightning near the Rogue River in early September, has grown rapidly to roughly 12,000–13,000 acres with new evacuation orders Friday.
  • Forecasts call for south-to-north winds that could improve Bay Area air by Sunday evening, and rain in southwest Oregon that fire crews hope will aid containment.
