Bay Area Marks Five Years Since 2020’s Orange Skies

Meteorologists traced the eerie daylight to northeast winds that ferried wildfire smoke over the region.

Overview

  • On Sept. 9, 2020, smoke from Northern California wildfires turned Bay Area skies a deep orange and made midday resemble night.
  • KRON4’s Lawrence Karnow said offshore winds from the northeast pushed the smoke long distances into the Bay Area.
  • The August Complex, ignited by lightning, burned more than 1 million acres across seven counties and ranked as California’s largest fire at the time.
  • Air quality stayed unhealthy after the event and took nearly a week to return to safer levels.
  • Photos and videos widely documented the scenes as pandemic-era commuters kept their headlights on.
