Corumbá fire, 20 January 2026 Corumbá
The fire started on 20 January 2026 in Corumbá, Brazil, and satellites saw it burning for 8 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 7,499 hectares from heat detections, spread across a single municipality.
It is the 184th largest in Mato Grosso do Sul since 2016 (of 506 with a page). Number 183 in Brazil in 2026, of 747.

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 0 days without rain (1 mm or more) when it started. Rain came after the fire: 4.0 mm on 28 Jan.
This area had burned before
96% of the perimeter overlaps earlier fires recorded since 2016: 2,536 ha in 2016, 3,730 ha in 2019, 2,156 ha in 2020, 4,992 ha in 2021, 1,695 ha in 2023, 618 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 7,162 ha that had burned before.

What happened to each town

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 20 January 2026 the air beside the fire reached 27 µg/m³ of PM2.5. That day averaged 19: 1.2 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Corumbá fire last?
- GWIS (Copernicus) dates it between 20 January 2026 and 27 January 2026: 8 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 7,499 hectares (75.0 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire only entered Corumbá (7,598 ha, 0.1 %).
- What was the weather like?
- During the fire the temperature reached 37.4 °C, humidity dropped to 27 % and gusts hit 40 km/h. The fire danger index (FWI) reached 17, class Moderate.
- 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.

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.
