Nova Maringá fire, 28 August 2025 Nova Maringá

Out · last detection 5 Sept 2025, 17:10 UTC

The fire started on 28 August 2025 in Nova Maringá, Brazil, and satellites saw it burning for 10 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 5,158 hectares from heat detections, spread across a single municipality.

It is the 1041th largest in Mato Grosso since 2016 (of 1996 with a page). Number 331 in Brazil in 2025, of 714.

It had gone more than two months without rain (1 mm or more) when it started. Rain came after the fire: 3.9 mm on 16 Sept.

This area had burned before

88% of the perimeter overlaps earlier fires recorded since 2016: 98 ha in 2016, 1,477 ha in 2020, 4,398 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 4,526 ha that had burned before.

How big is it?

10 km
It burned the equivalent of 3.3% of the area of London (52 km² against 1,583 km²).

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.

Frequently asked questions

How long did the Nova Maringá fire last?
GWIS (Copernicus) dates it between 28 August 2025 and 6 September 2025: 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 5,158 hectares (51.6 km²). It is an estimate: official national figures may differ.
Which municipalities burned?
The fire only entered Nova Maringá (5,192 ha, 0.4 %).
What was the weather like?
During the fire the temperature reached 38.2 °C, humidity dropped to 19 % and gusts hit 35 km/h. The fire danger index (FWI) reached 48, 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.

We will only use your email to reply about this report. Privacy. This is not an emergency service: if there is a fire now, call 193.

How we know this
  • Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery.
  • Dates from the perimeter: the VIIRS detections inside it did not change them. 313 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.

How we build fire pages: methodology ›

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.
