Utah Fire Map: Tracking Wildfires and Smoke Across Utah
Last updated 2026-09-22
Utah's wildfire information is coordinated through the state-federal Utah Fire Info interagency program, supplemented by a public wildfire dashboard, the national InciWeb system for large incidents, and the EPA/Forest Service smoke map. This guide maps which source answers which question — and pairs the fire picture with live smoke readings for Salt Lake City, Provo and Ogden.

Utah's official fire sources
Utah Fire Info (utahfireinfo.gov) is the state's official interagency wildfire site — a joint operation of the Utah Division of Forestry, Fire and State Lands with the federal land agencies. It is the starting point for active-incident listings and fire restrictions.
The public Utah wildfire dashboard (an ArcGIS dashboard linked from Utah Fire Info) shows near-real-time incident data — locations, sizes and status — compiled from agency reporting.
InciWeb (inciweb.nifc.gov) carries the large incidents on Forest Service and BLM land, which in Utah includes much of the central and southern terrain; each incident page has official updates and closures.
The AirNow Fire and Smoke Map (fire.airnow.gov) is the EPA/USFS joint map of fire detections, smoke plumes and hourly AQI — the authoritative view of where Utah's smoke is sitting right now.
Why Utah's geography makes smoke a valley problem
Utah's population sits in valley basins — Salt Lake, Utah and Cache — ringed by mountains. Wildfire smoke drains into those basins at night and, like winter inversions, can sit under a lid of stable air for days. A fire burning on the Wasatch Plateau or in the western desert can degrade air in Salt Lake City with no fire within a hundred miles of the city. That is why the fire maps answer "where is the fire" but the smoke map — or our live city pages — answers the question that changes your plans.
When the AQI climbs: close windows early (valley smoke arrives overnight), run a Corsi-Rosenthal box or HEPA purifier, and keep N95 masks on hand for outdoor time when the index is unhealthy.
Utah fire season and restrictions
Utah's main fire season runs June through September, with human-caused starts spiking around the July 4 holiday and lightning starts peaking in the monsoon-window thunderstorms of July and August. Fire restrictions — campfire bans, target-shooting restrictions, off-highway-vehicle limits — are set fire-by-fire and area-by-area; the authoritative listing is Utah Fire Info and the land agency managing the area you plan to visit. Check before any summer trip into the backcountry.
September 2026: how Utah's season ended
Utah's 2026 fire season peaked early. In the first days of September, wildfire trackers counted roughly seven active fires totaling about 142,000 acres across six counties. The largest by far was the Widemouth 2 Fire, which reached 129,742 acres and 98% containment by mid-September according to the WFCA fire map. By September 15, KUER reported no large active fires burning anywhere in Utah — the season effectively wrapped weeks ahead of the historical October close.
Containment does not mean smoke risk is zero: smoldering fire interiors and new starts can still degrade valley air on stagnant days. The live picture for the Wasatch Front is on our Salt Lake City and Provo pages; for the neighboring near-record season, see our Oregon fire map guide.
FAQ
What is the official Utah fire map?
Start with Utah Fire Info (utahfireinfo.gov), the state-federal interagency site, and the public wildfire dashboard it links for near-real-time incident data. For large fires on federal land, InciWeb (inciweb.nifc.gov) carries official incident pages. For smoke, use the AirNow Fire and Smoke Map (fire.airnow.gov).
Why is Salt Lake City smoky when there are no fires nearby?
Smoke travels hundreds of miles and pools in valley basins overnight. Wildfire smoke from fires anywhere upwind — central Utah, Nevada, even California — settles into the Salt Lake Valley under stable air, the same mechanism behind winter inversions. Check the AirNow smoke map to trace the plume back to its source fire.
Where can I check Salt Lake City's air quality right now?
Our live Salt Lake City page shows the current AQI with plain-language guidance, alongside pages for Provo and Ogden. For the plume view, the AirNow Fire and Smoke Map overlays smoke across the whole Wasatch Front.
Are there active fires in Utah right now (September 2026)?
As of mid-September 2026, no large active fires were burning in Utah — the early-September burst, led by the 129,742-acre Widemouth 2 Fire, reached 98% containment and KUER reported the season largely wrapped. Conditions change with new starts, so for the live picture check Utah Fire Info and the state wildfire dashboard; our Salt Lake City and Provo pages carry current air quality.
What was Utah's biggest wildfire in 2026?
The Widemouth 2 Fire in western Utah — about 129,742 acres, roughly 98% contained by mid-September per the WFCA fire map. It was the dominant incident of Utah's early-September burst, when trackers counted about seven active fires across six counties.
Does an N95 mask help with wildfire smoke in Utah?
A properly fitted N95 filters the fine PM2.5 that dominates wildfire smoke, and it is what health agencies recommend when AQI reaches unhealthy levels. It is especially relevant in Utah valleys, where multi-day smoke events are common during active fire season.

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.
