Monguno fire, November 2026 Monguno, Nganzai
Burning · last detection 5 Nov 2026, 11:59 UTC
The fire started on 4 November 2026 in Monguno, Nigeria, and satellites saw it burning for 2 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,102 hectares from heat detections, spread across 2 municipalities.
Number 293 in Nigeria in 2026, of 319.
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?
Satellites detected fire on 5 Nov 2026, 11:59 UTC. Everything suggests it is still burning. 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.

Frequently asked questions
- How long did the Monguno fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 4 November 2026 to 5 November 2026 (2 days). The perimeter dates it from 4 November 2026 to 4 November 2026.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 2,102 hectares (21.0 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Monguno (1,563 ha, 0.7 %); Nganzai (552 ha, 0.3 %).
- Is the Monguno fire still active?
- Yes: satellites detected fire on 5 Nov 2026, 11:59 UTC. Check the emergency service for the official status.
- What was the weather like?
- During the fire the temperature reached 40.0 °C, humidity dropped to 9 % and gusts hit 42 km/h. The fire danger index (FWI) reached 84, class Very extreme.
- 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 4 November 2026 to 4 November 2026. 31 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 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.
