Colniza fire, 6 July 2024 Colniza
The fire started on 6 July 2024 in Colniza, Brazil, and satellites saw it burning for 73 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 45,354 hectares from heat detections, spread across a single municipality.
This page is probably a fire complex, not a single fire. GWIS merges into one perimeter the fires that touch over weeks, which in large burning seasons can join dozens of separate fires. The total area is reliable; the origin and dates refer to the whole complex.
Other fire pages in the same area and on the same dates:
It is the 54th largest in Mato Grosso since 2016 (of 1996 with a page). Number 53 in Brazil in 2024, of 1301.

The weather it burned in
It had gone 44 days without rain (1 mm or more) when it started. Rain came after the fire: 2.8 mm on 19 Sept.
This area had burned before
89% of the perimeter overlaps earlier fires recorded since 2016: 2,853 ha in 2016, 3,697 ha in 2017, 280 ha in 2018, 3,304 ha in 2019, 3,080 ha in 2020, 1,946 ha in 2021, 44,004 ha in 2022, 21,543 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 40,276 ha that had burned before.

What happened to each town

Colniza where it started45,612 ha reached on 6 Jul1.6 %
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 2025Inside the perimeter there were about 0.30 hectares of built-up land and about 50 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.

CAMS · CopernicusOn 25 July 2024 the air beside the fire reached 853 µg/m³ of PM2.5. That day averaged 435: 29 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Colniza fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 6 July 2024 to 16 September 2024 (73 days). The perimeter dates it from 11 July 2024 to 14 September 2024.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 45,354 hectares (453.5 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Colniza (45,612 ha, 1.6 %).
- What was the weather like?
- During the fire the temperature reached 38.7 °C, humidity dropped to 21 % and gusts hit 37 km/h. The fire danger index (FWI) reached 44, class Very 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.

How we know this
- Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery; 3 polygons grouped in this page.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 11 July 2024 to 14 September 2024. 4,440 Suomi-NPP VIIRS detections on those dates.
- We have not matched this page with any official record.
- Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
- 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.
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.
