Air Quality Alert
Issued: 9:11 PM Dec. 21, 2025 – National Weather Service
111 PM PST Sun Dec 21 2025

...AIR QUALITY ALERT: MANDATORY WOOD-BURNING BAN IN EFFECT...

* WHAT...The South Coast AQMD has extended a mandatory wood-burning
ban for residents in the South Coast Air Basin. The No-Burn rule
bans burning wood, pellets, and manufactured fire logs in any indoor
or outdoor wood-burning device.

* WHERE...The South Coast Air Basin, which includes Orange County
and non-desert portions of Los Angeles, Riverside, and San
Bernardino counties. No-Burn Day alerts do not apply to areas above
3,000 feet in elevation, the Coachella Valley, or the High Desert.
Homes that rely on wood as a sole source of heat, low-income
households and those without natural gas service also are exempt
from the requirement.

* WHEN...Sunday and Monday.

* IMPACTS...Particles in smoke can get deep into the lungs and cause
health problems (including asthma attacks), increases in emergency
room visits, and hospitalizations. No-Burn Days are needed to
protect public health when fine particle pollution levels are
expected to be high anywhere in the South Coast Air Basin. No-Burn
Days are based on fine particle pollution levels that are forecasted
for an entire 24-hour period, which may not be reflected in
real-time air quality maps.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

To protect your health, check current and forecasted air quality
levels at www.aqmd.gov or download the mobile app at
www.aqmd.gov/mobileapp. When air quality is poor in your area,
limited extended or intense outdoor activity and remain inside with
windows and doors closed. Run your air conditioner and/or an air
purifier and avoid using devices that bring in outside air like a
swamp cooler or whole house fan if you have other ways to stay cool.
