Wildfires are 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 each year is increasing as climate change reduces winter snowpack, and produces hotter and drier summer weather.
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 Washington communities.

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.
