Oregon health authorities released updated air quality guidelines for youth outdoor activities this week, providing stricter thresholds and clearer guidance for schools, camps, and youth sports programs as wildfire smoke season gets underway across the Pacific Northwest.

The updated guidelines, released June 10 by the Oregon Health Authority and Oregon DEQ, rely on the Air Quality Index (AQI) — the color-coded system used to communicate health risk levels from air pollution and wildfire smoke — to help program operators make informed decisions about outdoor activity for children, who are more vulnerable to smoke-related health impacts than healthy adults.

AQI Thresholds for Youth Activities

The guidance recommends the following actions based on AQI levels:

  • Green (0-50): Air quality is satisfactory. No restrictions on outdoor activities.
  • Yellow (51-100): Unusually sensitive individuals should consider reducing prolonged outdoor exertion. Normal activities for most youth.
  • Orange (101-150): Unhealthy for sensitive groups. Limit prolonged outdoor activity for children, especially those with asthma or respiratory conditions. Move strenuous activities indoors.
  • Red (151-200): Unhealthy for all. Move outdoor activities inside or reschedule. Avoid extended time outdoors.
  • Purple (201-300) and above: Very unhealthy to hazardous. Cancel all outdoor activities. Keep children indoors with windows closed.

Why the Update Is Needed Now

Oregon DEQ tracks "unhealthy air quality days" from June 1 through October, the period that historically accounts for the vast majority of wildfire smoke impacts in the Pacific Northwest. With above-normal wildfire potential forecast across the region through September and temperatures expected to run above normal all summer, smoke events are likely to be more frequent and more intense than recent years.

The Washington Smoke Blog has noted that most of Washington and Oregon are "strongly favored" for above-normal temperatures this summer — a pattern that directly correlates with larger, more active wildfires and wider smoke plumes affecting populated areas west of the Cascades.

How to Monitor Air Quality

Several free tools help residents stay informed about current and forecast air quality:

  • AirNow Fire & Smoke Map (fire.airnow.gov) — Real-time smoke and air quality data from monitoring networks and satellite.
  • OregonAIR app — Free smartphone app from Oregon DEQ with notifications for air quality alerts.
  • Oregon Smoke Blog (oregonsmoke.org) — Daily smoke forecasts for specific areas and links to temporary monitors near active fires.
  • Washington Smoke Blog (wasmoke.blogspot.com) — Regional smoke forecasting and monitoring resources.

Oregon DEQ also offers email and text message air quality advisories. Residents in smoke-prone communities are encouraged to sign up now, before conditions deteriorate.

Health officials remind parents and program operators that when in doubt, moving activities indoors is always the right call. Smoke exposure in children can cause both short-term respiratory distress and contribute to longer-term health impacts.
