NO-BURN DAYS

Check Before You Burn season: From November through the end of February, residents are asked to check before burning wood in their fireplaces to limit emissions of fine particulate matter (PM2.5).

A No-Burn day is a 24-hour ban on wood-burning in residential fireplaces, stoves or outdoor fire pits in the South Coast Air Basin. South Coast AQMD forecasters call for residential No-Burn Days when PM2.5 is expected to reach Unhealthy levels due to air emissions and stagnant weather conditions.

South Coast AQMD’s No-Burn Day alerts do not apply to mountain communities above 3,000 feet in elevation, the Coachella Valley or High Desert, homes that rely on wood as a sole source of heat, low income households and those without natural gas service. Gas fireplaces are also exempt.

What is the AQI?

The U.S. Air Quality Index (AQI) is a tool for communicating air quality. It uses color-coded categories and provides statements for each category that tell you about air quality in your area, which groups of people may be affected, and steps you can take to reduce your exposure to air pollution.
Each category tells you about air quality in your area and the groups of people that may be affected. It also tells you steps you can take to reduce your exposure to air pollution and protect your health.
Higher values indicate worse air quality. EPA issues an AQI for five pollutants, including fine particle pollution (PM2.5 and PM10), carbon monoxide, nitrogen dioxide, and ozone (smog).
