Altamira fire, 5 August 2024 Altamira, Novo Progresso
The fire started on 5 August 2024 in Altamira, Brazil, and satellites saw it burning for 49 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 79,088 hectares from heat detections, spread across 2 municipalities.
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.

The weather it burned in
It had gone more than two months without rain (1 mm or more) when it started. Rain came after the fire: 5.1 mm on 25 Sept.
This area had burned before
81% of the perimeter overlaps earlier fires recorded since 2016: 12,860 ha in 2016, 28,878 ha in 2017, 3,278 ha in 2018, 18,922 ha in 2019, 26,167 ha in 2020, 2,313 ha in 2021, 52,700 ha in 2022, 1,033 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 64,003 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.
People and buildings inside the perimeter
GHSL 2025Inside the perimeter there were about 4.5 hectares of built-up land and about 300 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 · CopernicusOn 4 September 2024 the air beside the fire reached 1,289 µg/m³ of PM2.5. That day averaged 819: 55 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Altamira fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 5 August 2024 to 22 September 2024 (49 days). The perimeter dates it from 7 August 2024 to 16 September 2024.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 79,088 hectares (790.9 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Altamira (40,090 ha, 0.2 %); Novo Progresso (39,526 ha, 1.0 %).
- What was the weather like?
- During the fire the temperature reached 38.2 °C, humidity dropped to 20 % and gusts hit 40 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; 4 polygons grouped in this page.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 7 August 2024 to 16 September 2024. 5,376 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.
