Nganzai fire, 14 October 2026 Mafa, Nganzai

Dying down · last detection 25 Oct 2026, 12:42 UTC

The fire started on 14 October 2026 in Nganzai, Nigeria, and satellites saw it burning for 12 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 7,602 hectares from heat detections, spread across 2 municipalities.

It is the 31th largest in Borno since 2016 (of 462 with a page). Number 29 in Nigeria in 2026, of 264.

Is it still active?

No detections since 25 Oct 2026, 12:42 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.

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 · Copernicus

On 17 October 2026 the air beside the fire reached 64 µg/m³ of PM2.5. That day averaged 44: 3.0 times the WHO daily guideline (15).

Frequently asked questions

How long did the Nganzai fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 14 October 2026 to 25 October 2026 (12 days). The perimeter dates it from 17 October 2026 to 22 October 2026.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 7,602 hectares (76.0 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Mafa (7,003 ha, 2.0 %); Nganzai (651 ha, 0.3 %).
Is the Nganzai fire still active?
No fire detections since 25 Oct 2026, 12:42 UTC. A lack of detections is not an official extinction.
What was the weather like?
During the fire the temperature reached 37.2 °C, humidity dropped to 15 % and gusts hit 34 km/h. The fire danger index (FWI) reached 43, 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.

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 17 October 2026 to 22 October 2026. 121 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.
