Iracoubo fire, 1 November 2026 Iracoubo

Out · last detection 8 Nov 2026, 05:01 UTC

Satellites first detected fire on 1 November 2026 in Iracoubo, France. It was active for 8 days, with 13 heat detections and an area with fire of about 154 hectares rebuilt from them, spread across a single municipality.

The power measured by the satellite is low (20.0 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Copernicus has not yet published the burnt perimeter, which takes a few days to measure on satellite imagery. 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 municipality, rebuilt from heat detections (about 14 hectares per VIIRS pixel). An estimate until the official perimeter arrives. 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.

How a twin is chosen

  • Same area: fires that have already ended, less than 250 km from this one, since 2023.
  • Same start: we compare the FWI on the first day, the minimum humidity that day and the run of days without rain before it. The slider sets how much they may differ.
  • Only pages with final weather data (ERA5 reanalysis) calculated in the same way as this fire’s; agricultural and grass burns and pages with data under review are left out.
  • Fires burning at the same time as this one (a week before or after) are left out: they share the same spell of weather and do not count as a precedent.
  • They are sorted by similarity, and the outlines of the first five are drawn.

Frequently asked questions

How long did the Iracoubo fire last?
According to the heat detections seen by satellite, it burned from 1 November 2026 to 8 November 2026 (8 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. Heat detections rebuild about 154 hectares with fire (1.5 km²); Copernicus will publish the measured figure within days.
Which municipalities burned?
The fire only entered Iracoubo (154 ha, 0.1 %).
Is the Iracoubo fire still active?
No fire detections since 8 Nov 2026, 05:01 UTC. A lack of detections is not an official extinction.
Did the fire reach a town?
The fire started in Iracoubo and came within 10.7 km of its centre. That is the distance from the perimeter, or the nearest hotspot, to the point marking the centre; it does not mean it entered the houses.
What was the weather like?
During the fire the temperature reached 33.3 °C, humidity dropped to 48 % and gusts hit 50 km/h. The fire danger index (FWI) reached 28, class High.
Where does this data come from?
From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of France (geoBoundaries). 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 (≈ 154 ha) is estimated by counting VIIRS pixels with fire, about 14 ha each.
  • Dates of the first and last VIIRS detection of the cluster. 13 Suomi-NPP VIIRS detections on those dates.
  • Weather: ECMWF IFS model, provisional until the ERA5 reanalysis arrives.

How we build fire pages: methodology

Where this data comes from

The perimeter and land cover come from the Copernicus European Forest Fire Information System (EFFIS), measured on MODIS and Sentinel-2 imagery and published under CC BY 4.0. Heat detections come from the VIIRS sensors aboard Suomi-NPP and NOAA-20, distributed by NASA FIRMS at 375 m resolution. Municipal boundaries come from geoBoundaries ADM5 (Open Data Commons Attribution License 1.0). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ slightly from each country’s official figure.
