As the Pacific Northwest moves toward a fire season that forecasters are calling potentially severe, air quality officials and public health agencies are urging residents to prepare for smoke exposure months in advance — not just when fires are actively burning nearby.

May is both Wildfire Awareness Month and, coincidentally, National Air Quality Awareness Week (May 4-8), providing agencies a window to underscore the connection between wildfire activity and regional air quality degradation.

Why Smoke Is a Public Health Crisis

The U.S. Forest Service has described wildfire smoke as "the largest source of air pollution faced by the American public." During major Pacific Northwest fire seasons — 2017, 2018, 2020, and 2021 in particular — smoke from regional and even California fires drove Air Quality Index readings in cities like Bend, Medford, Boise, and Spokane to hazardous levels for days or weeks at a time.

Fine particulate matter (PM2.5) from smoke penetrates deep into the lungs and bloodstream, posing the greatest risk to children, the elderly, pregnant women, and those with cardiovascular or respiratory conditions. Even healthy adults experience symptoms including eye irritation, coughing, headaches, and reduced lung function during prolonged smoke exposure.

Resources for Staying Informed

Multiple agencies provide real-time and forecast air quality data for Northwest residents:

  • AirNow.gov — EPA's centralized platform provides real-time AQI maps, current conditions by zip code, and health guidance for all air quality categories.
  • Oregon DEQ Air Quality Today — oregon.gov/deq/aq tracks PM2.5, ozone, and nitrogen dioxide with station-level detail across Oregon.
  • NWS Boise Smoke Forecast — weather.gov/boi/smoke provides an experimental regional smoke dispersion forecast model for the Pacific Northwest.
  • Central Oregon Fire Information — centraloregonfire.org provides community-specific updates on prescribed fire smoke and wildfire conditions for Bend and surrounding areas.

Prescribed Fire Smoke: Short-Term Pain, Long-Term Gain

Residents across Central Oregon have already experienced smoke from spring prescribed burns on the Deschutes National Forest, with operations near Pine Mountain and Sisters generating visible smoke plumes visible from Bend and Highway 20. Officials remind the public that prescribed fire smoke — while temporarily unpleasant — represents a calculated trade-off: short-term, manageable smoke exposure now versus potentially catastrophic, weeks-long smoke events if fuels are left to accumulate and ignite under extreme summer conditions.

Preparing Your Home for Smoke Season

Health officials recommend residents take the following steps before fire and smoke season intensifies:

  • Identify a "clean room" in your home with minimal air leakage where you can shelter during heavy smoke events
  • Purchase MERV-13 or higher-rated HVAC filters and consider a portable HEPA air purifier
  • Have N95 respirators on hand (standard surgical masks provide minimal protection against PM2.5)
  • Sign up for local air quality alerts through AirNow or your county emergency management system
  • Plan ahead for outdoor workers, pets, and livestock who cannot easily retreat indoors

With above-normal fire potential forecast across the Northwest from June through August, public health officials say the window to prepare is now — before the smoke arrives.
