Smoke can be local even when the fire is far away
The AirNow Fire and Smoke Map shows PM2.5 smoke and air-quality information from wildfires and other sources, which can help with outdoor plans.
Smoke is one of those California details that can be confusing from the window. The sky may look hazy, the fire may be far away, and the air may still feel different from one valley or coast basin to the next.
The AirNow Fire and Smoke Map is a practical check for those days. It shows fine particle pollution, also called PM2.5, from wildfires and other sources. It can show monitor readings, smoke information, and nearby fire-related layers in one place.
Use it before a long outdoor day, a youth sports event, a hike, or a drive through a smoky area. Pair it with local health or school guidance when those are posted. A smoke map is not a personal medical answer, but it is a good way to see whether the day calls for a lighter plan, a different location, or a wait-and-see morning.
