Bonfim fire, 6 November 2026 Bonfim
Dying down · last detection 8 Nov 2026, 17:43 UTC
The fire started on 6 November 2026 in Bonfim, Brazil, and satellites saw it burning for 3 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 3,250 hectares from heat detections, spread across a single municipality.
Number 708 in Brazil in 2026, of 788.
GWIS near-real-time perimeter, from the layer that changed in October 2025: this fire is not compared with fires from earlier years, because since then the GWIS layer gives more and larger perimeters.

Fire radiative power (FRP) measures the energy the fire gives off when the satellite passes. Added up by day, it compares intensity, not area.

Is it still active?
No detections since 8 Nov 2026, 17:43 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.

This area had burned before
7% of the perimeter overlaps earlier fires recorded since 2016: 65 ha in 2016, 177 ha in 2020, 65 ha in 2022. Part of it burned more than once, so the yearly figures add up to more than the 213 ha that had burned before.

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.

Frequently asked questions
- How long did the Bonfim fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 6 November 2026 to 8 November 2026 (3 days). The perimeter dates it from 7 November 2026 to 8 November 2026.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 3,250 hectares (32.5 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Bonfim (3,272 ha, 0.4 %).
- Is the Bonfim fire still active?
- No fire detections since 8 Nov 2026, 17:43 UTC. A lack of detections is not an official extinction.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Brazil (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.
Report an error
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 7 November 2026 to 8 November 2026. 39 Suomi-NPP VIIRS detections on those dates.
- We have not matched this page with any official record.
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 3.0 Intergovernmental Organisations (CC BY 3.0 IGO)). 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.
