Guma fire, November 2020 Guma, Logo
The fire started on 30 November 2020 in Guma, Nigeria, and satellites saw it burning for 7 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,468 hectares from heat detections, spread across 2 municipalities.
It is the 51th largest in Benue since 2016 (of 83 with a page). Number 100 in Nigeria in 2020, of 160.

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.

Frequently asked questions
- How long did the Guma fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 30 November 2020 to 6 December 2020 (7 days). The perimeter dates it from 1 December 2020 to 3 December 2020.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 2,468 hectares (24.7 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Guma (2,166 ha, 0.7 %); Logo (317 ha, 0.2 %).
- What was the weather like?
- During the fire the temperature reached 36.1 °C, humidity dropped to 16 % and gusts hit 26 km/h. The fire danger index (FWI) reached 38, class High.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Nigeria (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.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 1 December 2020 to 3 December 2020. 65 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 4.0 International (CC BY 4.0)). 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.
