Wildfire information

Wildfires are a major threat to human health. Smoke from wildfires is the largest source of particle pollution in our state. Smoke inhalation causes breathing difficulties, 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 measures air pollution year-round. During wildfires, we may also add temporary monitors. For more information about wildfire smoke conditions and smoke forecasts, go to the Washington Smoke Information Blog. The colored dots on the map refer to the levels of air pollution and related health warnings.

This map uses EPA's Air Quality Index (AQI). There may be differences in the colors on this map and those on Washington's Air Monitoring Network. This is because Washington uses the Washington Air Quality Advisory (WAQA) index that is more protective of human health than the AQI. If the maps show different colors, use the map that shows more air pollution.

Smoke forecast

This map shows a forecast for smoke levels in areas across Washington. You can look at today's forecast or tomorrow's forecast to plan outdoor activities and reduce your exposure to air pollution. Colors on the map refer to the levels of air pollution and related health warnings.
