Nyirol fire, 28 October 2026 Nyirol, Uror
Dying down · last detection 13 Nov 2026, 12:04 UTC
The fire started on 28 October 2026 in Nyirol, South Sudan, and satellites saw it burning for 17 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 7,515 hectares from heat detections, spread across 2 municipalities.
Number 107 in South Sudan in 2026, of 246.
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.

Is it still active?
No detections since 13 Nov 2026, 12:04 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.

35% of the perimeter overlaps earlier fires recorded since 2016: 1,099 ha in 2017, 880 ha in 2021, 1,113 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 2,609 ha that had burned before.

Frequently asked questions
- How long did the Nyirol fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 28 October 2026 to 13 November 2026 (17 days). The perimeter dates it from 4 November 2026 to 12 November 2026.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 7,515 hectares (75.2 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Nyirol (7,436 ha, 1.0 %); Uror (125 ha, 0.0 %).
- Is the Nyirol fire still active?
- No fire detections since 13 Nov 2026, 12:04 UTC. A lack of detections is not an official extinction.
- What was the weather like?
- During the fire the temperature reached 40.5 °C, humidity dropped to 11 % and gusts hit 45 km/h. The fire danger index (FWI) reached 82, class Very extreme.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of South Sudan (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 4 November 2026 to 12 November 2026. 170 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.
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.
