Wildfire smoke is a major threat to human health. Smoke from wildfires is the largest source of particle pollution in Washington. Breathing in smoke causes wheezing and coughing, heart and lung disease, and death. The number of acres burned by wildfires is increasing as climate change reduces winter snowpack, and produces hotter and drier summers.
We monitor air quality conditions and forecast smoke levels. We also work with the Washington Departments of Natural Resources and Health, the U.S. Forest Service, and the National Weather Service to track wildfire smoke and protect people who live in Washington.

Current air quality conditions
We track air quality using air monitors around the state. Our network of monitors continuously measures air pollution year-round. During wildfires, we may also add temporary monitors.

Learn how to make a low-cost clean air fan. This simple fan-filter combination can reduce tiny, harmful particles in bad air — like wildfire smoke, wood smoke, dust, vehicle exhaust, and pesticide spray. Use it in a small room, with the windows and doors closed.
This map shows a five-day forecast for smoke levels across Washington. The forecast can help you plan outdoor activities and reduce your exposure to air pollution. Colors on the map refer to levels of air pollution and related health warnings.
