California Clean Air Day is Wednesday, October 5!
The goal of California Clean Air Day is to spread the message throughout California about air pollution and how it directly impacts all Californians’ health. By joining together for a unified day of action we can create new habits to clear the air for all members of California’s diverse communities.

When it comes to air pollution, we can all do our part. Whether you’re an individual, business, government agency or nonprofit organization, there are things we all can do to improve air quality and protect public health.

Take the Clean Air Day Pledge here by October 5.

Air Quality Forecast and Weather Discussion
Thursday through Saturday, an upper-level ridge of high pressure will reduce mixing and produce sunny skies with temperatures in the low-90s, promoting ozone development each day. Additionally, periods of calm to light westerly to northwesterly winds will hinder dispersion, allowing pollutants to accumulate in the Sacramento region. Furthermore, light smoke originating from agricultural fires in the northern Sacramento Valley will enhance ozone production. These conditions will yield Unhealthy for Sensitive Groups ozone levels on all three days.
