How long did the Coconino fire last?

According to the heat detections seen by satellite, it burned from 10 October 2026 to 10 October 2026 (1 day between the first and the last detection). There is no perimeter yet to date it.

How much area did it burn?

There is no official perimeter yet: NIFC has not published it. Heat detections rebuild about 728 hectares with fire (7.3 km²).

Which counties burned?

The fire only entered Coconino (728 ha, 0.0 %).

Is the Coconino fire still active?

No fire detections since 10 Oct 2026, 09:56 UTC. A lack of detections is not an official extinction.

What was the weather like?

During the fire the temperature reached 23.2 °C, humidity dropped to 20 % and gusts hit 67 km/h. The fire danger index (FWI) reached 19, class Moderate.

Where does this data come from?

From the official burnt perimeter of United States agencies (MTBS / NIFC, public domain), NASA FIRMS VIIRS hotspots and the administrative boundaries of United States. It is not an official report.

Coconino fire, 10 October 2026 Coconino

Out · last detection 10 Oct 2026, 09:56 UTC

Satellites first detected fire on 10 October 2026 in Coconino, United States. It has been active for 1 day, with 59 heat detections and an area with fire of about 728 hectares rebuilt from them, spread across a single county.

The power measured by the satellite is low (1.7 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

NIFC has not yet published the perimeter of this fire. For now the area is the one rebuilt from heat detections (about 14 hectares per pixel). When the perimeter arrives, this page picks it up on its own and keeps the same address.

Does something look wrong on this page?

This page is built from satellite data and official records, and it sometimes gets things wrong: the wrong dates, the wrong town, two fires merged into one, or something that was not a wildfire at all. If you know this fire first-hand (you live nearby, saw it, fought it or reported on it), tell us what really happened and we will check it.

Where this data comes from

The perimeter is official and in the public domain. For past years it comes from MTBS (Monitoring Trends in Burn Severity), run by the U.S. Geological Survey and the USDA Forest Service, which map it on Landsat and Sentinel-2 imagery. For the current and last year it comes from WFIGS at the National Interagency Fire Center (NIFC): incident perimeters mapped by fire crews, aircraft and imagery. Heat detections come from the VIIRS sensors aboard Suomi-NPP and NOAA-20, distributed by NASA FIRMS at 375 m resolution. County boundaries come from geoBoundaries ADM2 (Public Domain). The area per county is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ slightly from official figures.
