Monguno fire, 28 October 2025 Monguno, Nganzai
The fire started on 28 October 2025 in Monguno, Nigeria, and satellites saw it burning for 4 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 5,361 hectares from heat detections, spread across 2 municipalities.
It is the 67th largest in Borno since 2016 (of 457 with a page). Number 68 in Nigeria in 2025, of 294.

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 32 days without rain (1 mm or more) when it started.
This area had burned before
82% of the perimeter overlaps earlier fires recorded since 2016: 607 ha in 2016, 1,098 ha in 2017, 1,668 ha in 2018, 266 ha in 2019, 1,356 ha in 2020, 855 ha in 2021, 1,110 ha in 2022, 1,563 ha in 2023, 358 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 4,394 ha that had burned before.

Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance is from the town centre 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 28 October 2025 the air beside the fire reached 62 µg/m³ of PM2.5. That day averaged 31: 2.1 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Monguno fire last?
- GWIS (Copernicus) dates it between 28 October 2025 and 31 October 2025: 4 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 5,361 hectares (53.6 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Monguno (3,208 ha, 1.4 %); Nganzai (2,184 ha, 1.0 %).
- What was the weather like?
- During the fire the temperature reached 37.2 °C, humidity dropped to 17 % and gusts hit 31 km/h. The fire danger index (FWI) reached 46, class Very 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.
Emergency number: 112
Satellite cross-check
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.

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.
