Afuá fire, October 2026 Afuá

Burning · last detection 3 Nov 2026, 04:55 UTC

The fire started on 7 October 2026 in Afuá, Brazil, and satellites saw it burning for 28 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 3,789 hectares from heat detections, spread across a single municipality.

It is the 778th largest in Pará since 2016 (of 1112 with a page). Number 559 in Brazil in 2026, of 780.

Is it still active?

Satellites detected fire on 3 Nov 2026, 04:55 UTC. Everything suggests it is still burning. Satellites pass a few times a day and cloud or smoke can hide the fire: a lack of detections is not an official extinction. Each country’s emergency service declares a fire contained or out.

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.
Dates adjusted with the VIIRS detections inside the perimeter, which said 7 October 2026 to 2 November 2026. 108 Suomi-NPP VIIRS detections on those dates.
We have not matched this page with any official record.
Weather: ECMWF IFS model, provisional until the ERA5 reanalysis arrives.

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.
