Portland Fire Map: Wildfires and Smoke Around Portland, Oregon
Last updated 2026-09-22
"Portland fire" means one of two very different things: a structural fire handled by Portland Fire & Rescue, or a wildfire somewhere upwind dumping smoke on the metro area. This guide covers the wildfire-and-smoke case — the maps Portlanders actually need during fire season, and the live air quality that decides whether the day changes. For structure fires and PF&R incident news, the bureau's own channels are authoritative.

The maps Portland should watch
AirNow Fire and Smoke Map (fire.airnow.gov) — the EPA/Forest Service joint map, and the single most important one for Portland. It shows active fire detections, smoke plumes and hourly NowCast AQI; in a smoke event, Portland's monitors light up on this map before anything else affects your plans.
Oregon Department of Forestry (oregon.gov/odf/fire) — active fires on ODF's 16 million protected acres, which include the forestland west of the Cascades that most often sends smoke down the Columbia Gorge into the metro area.
State Fire Marshal dashboard (osfminfo.org) — evacuation levels and wildfire updates, produced with Oregon Emergency Management. Relevant to Portland mainly when fires threaten communities in the metro's wildland-urban fringe, such as the 2020 Riverside Fire era.
InciWeb (inciweb.nifc.gov) — large incidents on federal land, including the Cascade and Gorge districts whose fires push smoke into the Willamette Valley.
Why Portland's smoke can come from three states away
Portland's worst air days usually arrive from fires it cannot see on a local map. The metro area sits at the north end of the Willamette Valley, downwind of the Cascades and the Columbia Gorge — a funnel for smoke from eastern Oregon, Washington and even British Columbia. The 2020 Labor Day fires made this famous: a single weather inversion turned Portland into one of the worst-air cities on Earth for several days. The practical rule: when any large fire is active upwind, watch the AQI, not the perimeter. Our Portland page carries the live reading and what it means.
What to do when the smoke arrives
At Moderate AQI (51-100), unusually sensitive people should take it easy outdoors. From USG (101) onward, the general public starts feeling it — close windows, run filtration, and check our guides on keeping smoke out of your house and building a Corsi-Rosenthal box. At Unhealthy (151+), everyone should limit outdoor exertion; wear a properly fitted N95 mask if you must be out for extended time, and set up a clean room with a MERV-13 filter running.
Alerts worth setting before fire season
Three, set once: your county's emergency-alert system (Multnomah, Clackamas and Washington counties all run their own), the Watch Duty nonprofit app for vetted fire alerts and evacuation zones, and an AQI alert for the Portland monitor on AirNow or our Can I go outside? tool. That combination covers the two distinct risks — fire near you, and smoke on you — without requiring anyone to stare at a map all summer.
FAQ
Where is the smoke in Portland coming from?
Check the AirNow Fire and Smoke Map (fire.airnow.gov): it overlays smoke plumes with fire detections, so you can trace the plume over Portland back to its source fire. Often the answer is the Cascades or eastern Oregon — but smoke also reaches the metro area from Washington and British Columbia.
Is Portland smoky today?
Our live Portland air quality page shows the current AQI and what it means for your day. As of mid-September 2026, Oregon's fires are largely contained after a near-record season, so smoke days are occasional rather than persistent — but when any fire burns upwind, the Willamette Valley can fill fast. The statewide picture is in our Oregon fire map guide.
What is Portland's air quality right now?
Our live Portland page shows the current AQI from the monitoring network, updated continuously, with plain-language guidance for outdoor activity, windows and filtration. During smoke events it is the fastest answer to whether your day needs to change.
Which map shows wildfire evacuations near Portland?
The Oregon State Fire Marshal dashboard (osfminfo.org), produced with Oregon Emergency Management, carries official evacuation levels (Be Ready / Be Set / Go Now). County emergency-management pages issue the alerts themselves; the Watch Duty app is a convenient vetted overlay on top.
Does an N95 mask help with wildfire smoke?
Yes — a properly fitted N95 filters the fine PM2.5 particles that make wildfire smoke harmful, which is why it is the mask public-health agencies recommend when AQI is unhealthy. Cloth and surgical masks do not provide comparable protection.

Where this guidance comes from
We paraphrase published guidance rather than inventing our own. The primary sources for everything on this page:
- AirNow — Air Quality and Health (U.S. EPA): the AQI scale and its activity guidance by level.
- EPA — Particulate Matter (PM) Basics: what PM2.5 is and why it reaches deep into the lungs.
- CDC — Wildfire Smoke Safety: who is at higher risk, and when to seek care.
- EPA — Wildfires and Indoor Air Quality: clean rooms, filtration and what actually works indoors.
- AHAM: the CADR standard and the two-thirds room-sizing rule.
Our own AQI arithmetic is documented on the methodology page.
