Juara fire, 28 August 2024 Juara
The fire started on 28 August 2024 in Juara, Brazil, and satellites saw it burning for 10 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 24,446 hectares from heat detections, spread across a single municipality.
It is the 146th largest in Mato Grosso since 2016 (of 1996 with a page). Number 119 in Brazil in 2024, of 1301.

Where it burned
How it evolved, day by day
Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
The weather it burned in
It had gone 9 days without rain (1 mm or more) when it started.
This area had burned before
89% of the perimeter overlaps earlier fires recorded since 2016: 1,955 ha in 2016, 11,431 ha in 2017, 1,478 ha in 2018, 16,071 ha in 2019, 5 ha in 2020, 14,503 ha in 2021, 83 ha in 2022, 2,545 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 21,679 ha that had burned before.

What happened to each town
-
24,554 ha reached on 26 Aug1.1 %
Burnt area inside each municipality, from crossing the GWIS perimeter with administrative boundaries. The distance is from the town centre 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 · CopernicusOn 4 September 2024 the air beside the fire reached 274 µg/m³ of PM2.5. That day averaged 202: 13 times the WHO daily guideline (15).
Particles from the Copernicus CAMS model at the centre of the perimeter; these are not measurements in each town. The pale bar is the worst hour, the solid one the daily average.

Frequently asked questions
- How long did the Juara fire last?
- GWIS (Copernicus) dates it between 28 August 2024 and 6 September 2024: 10 days between the first and last heat detection of the perimeter.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 24,446 hectares (244.5 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Juara (24,554 ha, 1.1 %).
- What was the weather like?
- During the fire the temperature reached 38.5 °C, humidity dropped to 12 % and gusts hit 48 km/h. The fire danger index (FWI) reached 54, class Extreme.
- 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.
Emergency number: 193
Satellite cross-check
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
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.
