Isa fire, November 2026 Isa, Sabon Birni

Dying down · last detection 4 Nov 2026, 01:11 UTC

The fire started on 3 November 2026 in Isa, Nigeria, and satellites saw it burning for 2 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 2,278 hectares from heat detections, spread across 2 municipalities.

It is the 40th largest in Sokoto since 2016 (of 53 with a page). Number 258 in Nigeria in 2026, of 319.

Is it still active?

No detections since 4 Nov 2026, 01:11 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.

People and buildings inside the perimeter

GHSL 2025
Built-up area0.19 ha
Residents≈ 40

Inside the perimeter there were about 0.19 hectares of built-up land and about 40 residents (GHSL 2025, satellite-based estimate).

This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned. The GHSL 2025 epoch is a projection made from 2020 and earlier data.

The smoke

CAMS · Copernicus

On 2 November 2026 the air beside the fire reached 81 µg/m³ of PM2.5. That day averaged 49: 3.3 times the WHO daily guideline (15).

Frequently asked questions

How long did the Isa fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 3 November 2026 to 4 November 2026 (2 days). The perimeter dates it from 3 November 2026 to 3 November 2026.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 2,278 hectares (22.8 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Isa (1,248 ha, 0.6 %); Sabon Birni (1,044 ha, 0.4 %).
Is the Isa fire still active?
No fire detections since 4 Nov 2026, 01:11 UTC. A lack of detections is not an official extinction.
What was the weather like?
During the fire the temperature reached 38.1 °C, humidity dropped to 13 % and gusts hit 37 km/h. The fire danger index (FWI) reached 53, class 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 3 November 2026 to 3 November 2026. No 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.
  • Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2025, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.

How we build fire pages: methodology ›

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.
