Iberia fire, 14 October 2026 Iberia, St. Martin, Vermilion
Satellites first detected fire on 14 October 2026 in Iberia, United States. It was active for 10 days, with 37 heat detections and an area with fire of about 490 hectares rebuilt from them, spread across 3 counties.
The power measured by the satellite is low (26.2 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.

Area with fire inside each county, rebuilt from heat detections (about 14 hectares per VIIRS pixel). An estimate until NIFC publishes the official perimeter. The distance runs from the point marking the centre of each area to the nearest fire: staying a kilometre away does not mean it reached the houses.
The weather day by day
ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

Frequently asked questions
- How long did the Iberia fire last?
- According to the heat detections seen by satellite, it burned from 14 October 2026 to 23 October 2026 (10 days 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 490 hectares with fire (4.9 km²).
- Which counties burned?
- The fire entered 3 counties: Iberia (252 ha, 0.2 %); St. Martin (224 ha, 0.1 %); Vermilion (14 ha, 0.0 %).
- Is the Iberia fire still active?
- No fire detections since 24 Oct 2026, 20:12 UTC. A lack of detections is not an official extinction.
- What was the weather like?
- During the fire the temperature reached 31.7 °C, humidity dropped to 26 % and gusts hit 58 km/h. The fire danger index (FWI) reached 20, 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.
Where to verify it
A satellite detection is not an official report. Final figures and the fire’s status are published by each country’s emergency service.

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.

How we know this
- No perimeter yet: the area (≈ 490 ha) is estimated by counting VIIRS pixels with fire, about 14 ha each.
- Dates of the first and last VIIRS detection of the cluster. 37 Suomi-NPP VIIRS detections on those dates.
- Weather: ECMWF IFS model, provisional until the ERA5 reanalysis arrives.
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.
