Washington Smoke Map

*The map above is not able to display all state air quality monitors. Click here to see all monitors in Washington: WA Ecology Air Monitors

Note: Some users might notice intermittent discrepancies in colors shown on the map of air quality monitors above, and those reported on the Department of Ecology's official page. This is because Ecology believes their method of calculating the air quality category (i.e. “Good”, “Moderate”, Unhealthy” etc) is more protective of public health in Washington. 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).

Burn Ban Information Page

Cold weather and stagnant air can lead to an unhealthy build-up of wood smoke pollution.  Find out if there is a burn ban in your area by visiting the Washington state burn ban page:

Now that was a bad wildfire year!

Wildfires in 2015 burned more acres in Washington State than the last 5 years combined, according to data from the Northwest Interagency Coordination Center. Abnormally warm temperatures, a snow drought last winter, early snow melt this spring and a mostly dry summer were among the reasons.

Acres burned by Washington wildfires
2010
56,820

17,480
2012
259,526
2013
152,603
2014

2015
1,005,423 (as of September 30th)

In addition to the tragic loss of lives and property, many people were forced to breathe heavily polluted air for several days. Eastern Washingtonians were exposed to an average of about 11 days where air quality was either Unhealthy or worse, compared to an average of about 7 days in recent years with bad wildfires.

As can be expected, air quality varied widely from place to place. Omak for instance saw air quality degrade much more than it did in past years, while Wenatchee did not see air that was as bad as they did in 2012. Not all smoke plumes are measured by the network of air quality monitoring sites. Several temporary monitors placed in smoke impacted communities at different times recorded poor air quality, but their data have not been considered in the above analysis.

While the human body can recover from short term exposure to wildfire smoke, it is well known that smoke inhalation causes breathing difficulties among people with prior respiratory or cardiovascular diseases. Elderly people, pregnant women, infants and children can be susceptible at lower pollution levels. Extreme smoke levels can trigger heart attacks or strokes, even among healthy people. 

As we transition from wildfire season to home heating season, the public is encouraged to observe any burn bans that might be imposed in case of stagnant air and take necessary precautions to limit exposure to impaired air. If you are a wood burner, make sure you only burn dry, seasoned firewood in small, hot fires. A low-polluting woodstove or pellet stove would make an excellent Christmas gift. Your family and neighbors will thank you for it.
