Dianópolis fire, October 2026 Dianópolis, Novo Jardim
The fire started on 7 October 2026 in Dianópolis, Brazil, and satellites saw it burning for 5 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 3,036 hectares from heat detections, spread across 2 municipalities.
It is the 1224th largest in Tocantins since 2016 (of 1242 with a page). Number 738 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 2 days without rain (1 mm or more) when it started. Rain came after the fire: 18.5 mm on 15 Oct.
This area had burned before
31% of the perimeter overlaps earlier fires recorded since 2016: 19 ha in 2016, 740 ha in 2017, 762 ha in 2019, 211 ha in 2020, 73 ha in 2022, 335 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 930 ha that had burned before.

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 11 October 2026 the air beside the fire reached 42 µg/m³ of PM2.5. That day averaged 25: 1.7 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 Dianópolis fire last?
- GWIS (Copernicus) dates it between 7 October 2026 and 11 October 2026: 5 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 3,036 hectares (30.4 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Dianópolis (2,947 ha, 0.9 %); Novo Jardim (107 ha, 0.1 %).
- Is the Dianópolis fire still active?
- No fire detections since 11 Oct 2026, 16:26 UTC. A lack of detections is not an official extinction.
- What was the weather like?
- During the fire the temperature reached 38.5 °C, humidity dropped to 11 % and gusts hit 44 km/h. The fire danger index (FWI) reached 50, 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.

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.
