Nova Mamoré fire, July 2024 Nova Mamoré, Campo Novo de Rondônia
The fire started on 15 July 2024 in Nova Mamoré, Brazil, and satellites saw it burning for 60 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 96,306 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.
Other fire pages in the same area and on the same dates:
It is the 2th largest in Rondônia since 2016 (of 300 with a page). Number 21 in Brazil in 2024, of 1301.

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. Rain came after the fire: 5.0 mm on 27 Sept.
This area had burned before
79% of the perimeter overlaps earlier fires recorded since 2016: 19,929 ha in 2016, 24,432 ha in 2017, 20,384 ha in 2018, 40,770 ha in 2019, 19,242 ha in 2020, 52,562 ha in 2021, 51,115 ha in 2022, 20,264 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 76,221 ha that had burned before.

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 24 July 2024 the air beside the fire reached 542 µg/m³ of PM2.5. That day averaged 323: 22 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 Nova Mamoré fire last?
- GWIS (Copernicus) dates it between 15 July 2024 and 12 September 2024: 60 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 96,306 hectares (963.1 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Nova Mamoré (96,929 ha, 9.6 %); Campo Novo de Rondônia (9 ha, 0.0 %).
- What was the weather like?
- During the fire the temperature reached 39.6 °C, humidity dropped to 15 % and gusts hit 50 km/h. The fire danger index (FWI) reached 47, 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.
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
How we know this
- Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery; 11 polygons grouped in this page.
- Dates from the perimeter: the VIIRS detections inside it did not change them. 5,711 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.
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.
