Welcome to the Washington Smoke blog, a partnership between state, county, and federal agencies, and Indian Tribes. We coordinate to collectively share info for Washington communities affected by wildfire smoke.
If the air monitoring map doesn't display here, links to additional monitoring maps can be found at the Air Quality Now tab.
You may notice small differences in colors shown on the map on this website, and those reported on the Washington's Air Monitoring Network. The map on this website uses the national air quality reporting system called the Air Quality Index (AQI) for calculating the air quality health category. However, the state uses the Washington Air Quality Advisory (WAQA) system of calculating air quality. Both use color-coded categories to show when air quality is good, moderate, or unhealthy. The difference is that the state's WAQA is based on lower levels of fine particle pollution than the federal AQI, providing an earlier alert of potential air quality risks. If in doubt as to which better represents public health risk, use the more stringent of the two (i.e. the map showing worse air quality). See the WAQA color guidance, also en Español.
