VISTA, Calif. — Residents across Vista and other North County San Diego communities reported seeing large plumes of smoke on Sunday as firefighters responded to a brush fire burning within Marine Corps Base Camp Pendleton.
Although the wildfire was confined to the military installation, smoke drifted across surrounding communities, prompting air quality concerns and increased public attention.
Brush Fire Breaks Out on Camp Pendleton
According to fire officials, the vegetation fire ignited at approximately 2:10 p.m. inside a training area on Marine Corps Base Camp Pendleton.
Fueled by dry vegetation, the blaze quickly expanded to an estimated 150 acres as firefighters worked to slow its spread and protect nearby infrastructure.
The fire remained within the boundaries of the base, and officials reported no evacuation orders for Vista or other off-base communities.
Firefighters Continue Containment Efforts
Camp Pendleton fire personnel remained the lead agency managing the incident, focusing on containing the blaze before changing weather conditions could increase fire activity.
Fire crews were working to:
- Build and strengthen containment lines.
- Monitor shifting wind conditions.
- Protect military facilities and nearby communities.
- Deploy available firefighting resources to slow the fire’s spread.
- Track smoke movement across North County San Diego.
Officials continued evaluating fire behavior throughout the response.

Smoke Impacts Across North County
While the flames remained inside Camp Pendleton, smoke was visible across much of North County, including Vista.
Fire officials noted that coastal wind patterns frequently carry wildfire smoke from inland fires and military training areas into surrounding cities, even when there is no immediate threat to residential neighborhoods.
Residents with asthma, respiratory illnesses, or other health conditions sensitive to smoke are encouraged to monitor local air quality reports and limit prolonged outdoor activity if smoke becomes heavy.

Emergency personnel emphasized that visible smoke over Vista does not necessarily indicate an active wildfire within the city itself.
