Smelled smoke in Campbell on Wednesday? It came from a planned burn on Angel Island
If you smelled smoke in Campbell on Wednesday afternoon, or noticed a haze to the north, there was no wildfire. It came from a prescribed burn on Angel Island — the largest island in San Francisco Bay, nearly 50 miles north of Campbell — where fire crews were deliberately clearing dry grass and brush.
What happened
Fire crews resumed a planned burn on Angel Island on Wednesday, two weeks after it was paused. CAL FIRE, the Marin County Fire Department and California State Parks began the operation on September 8 with a goal of treating 260 acres, but stopped after about 62 acres following discussions with the Bay Area Air Quality Management District.
Wednesday brought a new weather window. Crews treated another 85 acres before stopping at about 2:15 p.m., Bay City News reported, and no more burning is planned for the rest of this week. Roughly 100 acres remain, to be finished on a later day with favorable conditions.
How far the smoke travelled
The smoke was heaviest in San Francisco and the East Bay. KALW reported elevated air-quality readings in parts of central and eastern San Francisco, and the cities of Richmond and San Pablo sent alerts to residents. Hindustan Times reported that residents as far south as San Jose and Santa Clara also noticed smoke. State Parks says smoke from a burn day can stay visible for up to three days.
Why burn on purpose
The burns target grassland and coastal scrub — dry fuel that builds up when an area goes years without the small, low-intensity fires it once had. CAL FIRE Division Chief Sean Jerry described the goal of the first phase as "reducing the chance of a catastrophic fire on the island." Marin County Fire has made the practical case too: clearing dry vegetation now means a future fire there would take far fewer engines to control. Each burn day is scheduled with the Bay Area Air Quality Management District and depends on weather that will carry smoke up and away.
If you see smoke from a planned burn
- Don't call 911 about Angel Island smoke. State Parks asks residents not to, so emergency lines stay clear for real emergencies.
- If the smell bothers you, KALW's advice was to stay indoors, close windows and run an air purifier if you have one.
- For updates, State Parks points to the Angel Island State Park website and social accounts, and the Watch Duty app.
Why this is a Campbell homeowner's question too
Wildfire risk shows up in real estate as paperwork before it ever shows up as smoke. Every California home sale comes with a Natural Hazard Disclosure, which states whether the property sits in a state-mapped very high fire hazard severity zone or a wildland area. Across Campbell that answer varies by address, and it is in the report a seller provides — worth reading before an offer, not after.
