Fires near South San Francisco right now
NASA's VIIRS sensors detected 10 thermal hotspots in 5 separate clusters within 80 km of South San Francisco, California, United States in the last 48 h. The closest is 33 km N of the city centre (5 km WNW of Richmond), with 2 detections and a peak fire radiative power of 1 MW, which is low-intensity for a single 375 m pixel.
None of the clusters is within 25 km of the centre, so the city itself is not in the immediate fire area, but smoke can travel hundreds of kilometres.
Every nearby cluster is low intensity (peak under 10 MW), which is typical of agricultural or garden burning, industrial heat sources such as steel works or flares, or small fires rather than a spreading wildfire.
The largest nearby cluster by detections is 48 km NNE (at Martinez) with 4 detections; first seen Sat 3 am and last seen Sun 2 am local time.
Across United States there are 573 fire clusters in the same window, 44 of them in California.
| Fire cluster | From city | Detections | Peak FRP | First seen | Last seen |
|---|---|---|---|---|---|
| 5 km WNW of Richmond | 33 km N | 2 | 1 MW | Sat 3:13 am | Sun 2:56 am |
| 4 km NW of Milpitas | 47 km ESE | 2 | 1 MW | Sat 3:15 am | Sun 2:56 am |
| at Martinez | 48 km NNE | 4 | 1 MW | Sat 3:13 am | Sun 2:56 am |
| 6 km SE of Fairfield | 72 km NNE | 1 | 0 MW | Sat 3:13 am | Sat 3:13 am |

Smoke and wind
Wind at South San Francisco is from the ENE at 5 km/h (gusts 5 km/h), so smoke near the city drifts toward the WSW. Relative humidity is 45% and the temperature 21°C.
South San Francisco is not directly downwind of the nearest fire at the moment, though winds shift and plumes from larger fires can still reach the city.
Smoke shows up first as PM2.5 on air-quality monitors; the South San Francisco air quality page has the live reading.
Evacuations and official information
GodsView shows satellite detections only. It does not know fire perimeters, containment or evacuation zones. Always follow evacuation orders from local authorities.
InciWeb (inciweb.wildfire.gov) lists federal wildfire incidents; in this state also check CAL FIRE (fire.ca.gov/incidents). Evacuation orders come from county sheriffs and emergency management, often via Genasys Protect (protect.genasys.com) or local alert apps.
About satellite fire detections
Satellite thermal hotspots are not all wildfires: gas flares, steel works, volcanoes and planned agricultural or prescribed burns show up too. VIIRS passes over most places about twice a day, so a fire can start or grow between passes, and thick smoke or cloud can hide one.
Fire radiative power (FRP) is the heat a fire gives off, in megawatts per pixel: under 10 MW is usually a small or smouldering fire, over 100 MW an intense flaming front.
