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.

Is it still active?

Satellites detected fire on 6 Nov 2026, 16:41 UTC. Everything suggests it is still burning. Satellites pass a few times a day and cloud or smoke can hide the fire: a lack of detections is not an official extinction. Each country’s emergency service declares a fire contained or out.

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.

Its twins: fires that started in the same weather

It started with an FWI of 17.5, a minimum humidity of 62% and 2 days without rain. Fires in the area that started in weather like this since 2023: 3.

What happened to them

Fires in the area that started in similar weather: 3. With fewer than 15 we give no figures: they would be more noise than signal.

This is a bank of analogues: it shows what usually happens, not what will happen. With fewer than 15 twins we give no figures. How we calculate it

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 Macouria fire last?
According to the heat detections seen by satellite, it burned from 28 October 2026 to 6 November 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. Heat detections rebuild about 854 hectares with fire (8.5 km²); Copernicus will publish the measured figure within days.
Which municipalities burned?
The fire entered 3 municipalities: Macouria (462 ha, 1.5 %); Kourou (392 ha, 0.2 %); Montsinéry-Tonnegrande (0 ha, 0.0 %).
Is the Macouria fire still active?
Yes: satellites detected fire on 6 Nov 2026, 16:41 UTC. Check the emergency service for the official status.
Did the fire reach a town?
The fire started in Macouria and came within 0.9 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 32.3 °C, humidity dropped to 53 % and gusts hit 46 km/h. The fire danger index (FWI) reached 25, 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 (≈ 854 ha) is estimated by counting VIIRS pixels with fire, about 14 ha each.
  • Dates of the first and last VIIRS detection of the cluster. 84 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.
