Smoke continues to affect the Sacramento region due to various fires burning in northern California, plus smoke is being transported from offshore caused by fires burning in the Pacific Northwest. If you see or smell smoke in your area you should stay indoors and avoid outdoor activities. Check the fire page to see the latest PM2.5 readings at monitoring sites in the region and to get local air district information.


Smoke Still Lingers
The Sacramento region is still getting smoke from offshore. While most of it is aloft, there may be some areas of the region where it's seen at ground-level.

Remember to check current conditions before outdoor activities since air pollution levels can vary from one place to another. It's always a good idea to check. If you haven't already, download the free Sacramento Region Air Quality app to know what you're breathing.

Please continue to drive less when you can to help reduce pollution that contributes to the region's air quality problem.

Air Quality Forecast and Weather Discussion
Tuesday through Thursday, slightly cooler temperatures will limit ozone formation in the Sacramento region, and moderate onshore winds will increase pollutant dispersion. However, these winds will transport smoke from offshore into the Sacramento area, increasing particle concentrations and enhancing ozone formation. As a result, ozone levels will be Unhealthy for Sensitive Groups on all three days.
