Ibba fire, 1 January 2026 Ibba
The fire started on 1 January 2026 in Ibba, South Sudan, and satellites saw it burning for 9 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 6,149 hectares from heat detections, spread across a single municipality.
It is the 258th largest in Western Equatoria since 2016 (of 361 with a page). Number 121 in South Sudan in 2026, of 183.

Where it burned
How it evolved, day by day
Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
The weather it burned in
It had gone 16 days without rain (1 mm or more) when it started.
This area had burned before
98% of the perimeter overlaps earlier fires recorded since 2016: 4,957 ha in 2016, 1,808 ha in 2017, 1,066 ha in 2018, 512 ha in 2019, 3,046 ha in 2020, 1,638 ha in 2022, 1,058 ha in 2023, 2,366 ha in 2024, 754 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 6,050 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.
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.

The smoke
CAMS · CopernicusOn 5 January 2026 the air beside the fire reached 194 µg/m³ of PM2.5. That day averaged 113: 7.6 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Ibba fire last?
- GWIS (Copernicus) dates it between 1 January 2026 and 9 January 2026: 9 days between the first and last heat detection of the perimeter.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 6,149 hectares (61.5 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Ibba (6,190 ha, 0.6 %).
- What was the weather like?
- During the fire the temperature reached 36.5 °C, humidity dropped to 18 % and gusts hit 36 km/h. The fire danger index (FWI) reached 41, class Very high.
- 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 from the perimeter: the VIIRS detections inside it did not change them. 246 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.
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.
