Check Before You Burn Season Starts November 1

Beginning November 1 through the end of February 2021, local residents are asked to “Check Before You Burn” and refrain from burning wood in residential fireplaces, backyard fire pits and wood stoves on days when unhealthy air quality is forecast.

During this time, South Coast AQMD issues periodic mandatory no-burn alerts for days when emissions and stagnant weather conditions are expected to raise fine particulate pollution to unhealthy levels.

There are three ways you can Check Before You Burn:

  • E-mail Notification Program – sign up at to receive Air Alerts on air quality and to be notified when a mandatory no-burn alert has been issued for your neighborhood.

  • Check Before You Burn Map - visit our Check Before You Burn Map for daily forecast information.

  • Toll-Free Phone Number – call 866-966-3293 for daily Check Before You Burn information.

The Check Before You Burn program was created to reduce pollution and protect public health from the harmful emissions of wood burning. Despite steady progress toward improved air quality, the South Coast Air Basin still has the worst pollution in the country.

Smoke from wood can emit fine particulate matter, otherwise known as PM2.5. Long-term exposure to PM2.5 can lead to reduced lung function and chronic bronchitis. In some cases, prolonged exposure to this harmful substance may even lead to premature death. Short-term exposure can make existing respiratory conditions such as asthma or lung disease worse. Young children and the elderly are especially vulnerable to the effects of PM2.5.
