Ouandja fire, 16 December 2025 Ouandja, Vokouma, Ouandja Kotto

Out · last detection 21 Jan 2026, 12:28 UTC

The fire started on 16 December 2025 in Ouandja, Central African Republic, and satellites saw it burning for 36 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 106,456 hectares from heat detections, spread across 4 municipalities.

This page is probably a fire complex, not a single fire. GWIS merges into one perimeter the fires that touch over weeks, which in large burning seasons can join dozens of separate fires. The total area is reliable; the origin and dates refer to the whole complex.

Number 6 in Central African Republic in 2025, of 72.

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.

This area had burned before

83% of the perimeter overlaps earlier fires recorded since 2016: 55,887 ha in 2016, 14,887 ha in 2017, 2,464 ha in 2018, 16,461 ha in 2019, 27,259 ha in 2020, 23,753 ha in 2021, 22,327 ha in 2022, 12,912 ha in 2023, 19,281 ha in 2024, 1,247 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 88,250 ha that had burned before.

Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. 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.

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 Ouandja fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 16 December 2025 to 20 January 2026 (36 days). The perimeter dates it from 18 December 2025 to 15 January 2026.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 106,456 hectares (1,064.6 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 4 municipalities: Ouandja (36,225 ha, 1.8 %); Vokouma (25,485 ha, 2.8 %); Ouandja Kotto (24,805 ha, 4.1 %); Yalinga (20,336 ha, 0.5 %).
What was the weather like?
During the fire the temperature reached 35.4 °C, humidity dropped to 8 % and gusts hit 48 km/h. The fire danger index (FWI) reached 60, class Extreme.
Where does this data come from?
From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Central African Republic (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
  • Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery; 7 polygons grouped in this page.
  • Dates adjusted with the VIIRS detections inside the perimeter, which said 18 December 2025 to 15 January 2026. 3,816 Suomi-NPP VIIRS detections on those dates.
  • We have not matched this page with any official record.
  • Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
  • 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.

How we build fire pages: methodology

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 ADM3 (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.
