Barão de Melgaço fire, October 2026 Barão de Melgaço, Poconé

Burning · last detection 14 Nov 2026, 17:26 UTC

The fire started on 31 October 2026 in Barão de Melgaço, Brazil, and satellites saw it burning for 15 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 7,065 hectares from heat detections, spread across 2 municipalities.

Number 209 in Brazil in 2026, of 797.

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.

Is it still active?

Satellites detected fire on 14 Nov 2026, 17:26 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.

This area had burned before

72% of the perimeter overlaps earlier fires recorded since 2016: 2,259 ha in 2016, 2,644 ha in 2017, 966 ha in 2018, 3,193 ha in 2019, 4,916 ha in 2020, 1,875 ha in 2021, 1,718 ha in 2022, 4,083 ha in 2023, 1,531 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 5,054 ha that had burned before.

How big is it?

10 km
It burned the equivalent of 4.5% of the area of London (71 km² against 1,583 km²).

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 area0.13 ha
Residents< 20

Inside the perimeter there were about 0.13 hectares of built-up land and almost nobody lived there (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.

Frequently asked questions

How long did the Barão de Melgaço fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 31 October 2026 to 14 November 2026 (15 days). The perimeter dates it from 31 October 2026 to 12 November 2026.
How much area did it burn?
The perimeter GWIS (Copernicus) rebuilt from heat detections is 7,065 hectares (70.6 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Barão de Melgaço (7,020 ha, 0.6 %); Poconé (95 ha, 0.0 %).
Is the Barão de Melgaço fire still active?
Yes: satellites detected fire on 14 Nov 2026, 17:26 UTC. Check the emergency service for the official status.
What was the weather like?
During the fire the temperature reached 37.8 °C, humidity dropped to 36 % and gusts hit 47 km/h. The fire danger index (FWI) reached 26, class High.
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.

We will only use your email to reply about this report. Privacy. This is not an emergency service: if there is a fire now, call 193.

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 31 October 2026 to 12 November 2026. 257 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 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.
