Loug-Chari fire, October 2026 Loug-Chari
Dying down · last detection 4 Nov 2026, 12:18 UTC
The fire started on 21 October 2026 in Loug-Chari, Chad, and satellites saw it burning for 15 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,443 hectares from heat detections, spread across a single municipality.
Number 144 in Chad in 2026, of 214.
GWIS near-real-time perimeter, from the layer that changed in August 2025: this fire is not compared with fires from earlier years, because since then the GWIS layer gives more and larger perimeters.
The power measured by the satellite is low (28.6 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Is it still active?
No detections since 4 Nov 2026, 12:18 UTC. That usually means no flame is visible from space any more, although hotspots may remain. 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.

or tap the mapThis is not an official warning. It is a global model forecast with cells of about 25 km, at the centre of the fire: it cannot see valley winds or the winds the fire itself creates. The fan shows where the wind blows, not where the fire will spread. If in doubt, follow what the authorities say.
Forecast: ECMWF IFS 0.25° (European Centre for Medium-Range Weather Forecasts), served by our own Open-Meteo instance; the chance of rain comes from the ECMWF ensemble. Variables: wind and gusts at 10 m, wind at 850 hPa, relative humidity and temperature at 2 m, rain. Open-Meteo.com (CC BY 4.0).

How it is worked out: wind shift = a change of more than 60° in 6 h or less, with at least 15 km/h before and after; no overnight recovery = peak humidity between 8 pm and 8 am stays below 55 %; useful rain = 2 mm or more in 6 h. The fan opens 18° plus however much the wind varies within ±3 h and reaches 25 km beyond the edge of the fire: one model cell, not a rate of spread. Methodology

Inside the perimeter there was no noticeable built-up land and almost nobody lived there (GHSL 2025, satellite-based estimate).
This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned. The GHSL 2025 epoch is a projection made from 2020 and earlier data.

Frequently asked questions
- How long did the Loug-Chari fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 21 October 2026 to 4 November 2026 (15 days). The perimeter dates it from 21 October 2026 to 28 October 2026.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 2,443 hectares (24.4 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Loug-Chari (2,461 ha, 0.2 %).
- Is the Loug-Chari fire still active?
- No fire detections since 4 Nov 2026, 12:18 UTC. A lack of detections is not an official extinction.
- What was the weather like?
- During the fire the temperature reached 40.4 °C, humidity dropped to 13 % and gusts hit 29 km/h. The fire danger index (FWI) reached 52, class Extreme.
- What weather is expected at the fire over the next 72 hours?
- The wind is blowing from the east and pushing westwards; no sharp shifts are expected until Sun 8, 10:00. No overnight recovery: humidity stays at or below 27 % (Thu 5, 20:00 – Fri 6, 07:00). No overnight recovery: humidity stays at or below 28 % (Fri 6, 20:00 – Sat 7, 07:00). No overnight recovery: humidity stays at or below 22 % (Sat 7, 20:00 – Sun 8, 07:00). Times are local time at the fire. ECMWF IFS forecast (Open-Meteo) computed 5 Nov 2026, 05:53 UTC; this is not an official warning.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Chad (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.
Report an error
How we know this
- Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 21 October 2026 to 28 October 2026. 30 Suomi-NPP VIIRS detections on those dates.
- We have not matched this page with any official record.
- Weather: ECMWF IFS model, provisional until the ERA5 reanalysis arrives.
- Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2025, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.
Where this data comes from
The perimeter comes from the Copernicus Global Wildfire Information System (GWIS), which rebuilds it from MODIS and VIIRS heat detections and publishes it under CC BY 4.0. It is not measured on imagery as in Europe, so it is an estimate. 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 ADM2 (Creative Commons Attribution 3.0 Intergovernmental Organisations (CC BY 3.0 IGO)). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ from each country’s official figure.
