The fire started on 6 August 2026 in Santiago de Cassurrães e Póvoa de Cervães, Portugal, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 105 hectares from satellite imagery, spread across 2 municipalities. According to ICNF, it was detected on 6 August 2026 at 15:06 and declared extinguished on 6 August 2026.

It is the 11th largest in Mangualde since 2016 (of 13 with a page). Number 77 in Portugal in 2026, of 78.

This area had burned before

100% of the perimeter overlaps earlier fires recorded since 2016: 106 ha in 2017, 28 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 106 ha that had burned before.

Land cover inside the perimeter according to Corine Land Cover, as reported by Copernicus.

GHSL 2025
Built-up area0.32 ha
Residents< 20

Inside the perimeter there were about 0.32 hectares of built-up land and almost nobody lived there (GHSL 2025, satellite-based estimate).

This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned. The GHSL 2025 epoch is a projection made from 2020 and earlier data.

Frequently asked questions

How long did the Mangualde fire last?
The official perimeter only gives the start date (6 August 2026). The end comes from the heat detections inside the perimeter: it burned until 6 August 2026 (1 day from 6 August 2026), the last day with detections before more than 10 days in a row without any, so it is approximate. According to ICNF, it was detected on 6 August 2026 at 15:06 and declared extinguished on 6 August 2026.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 105 hectares (1.0 km²). Official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Santiago de Cassurrães e Póvoa de Cervães (90 ha, 3.0 %); Abrunhosa-a-Velha (15 ha, 0.9 %).
Did the fire reach a town?
The fire came within 1.1 km of the centre of Abrunhosa-a-Velha, the closest of the areas it touched. That is the distance from the perimeter, or the nearest hotspot, to the point marking the centre; it does not mean it entered the houses.
What was the weather like?
During the fire the temperature reached 32.4 °C, humidity dropped to 27 % and gusts hit 35 km/h. The fire danger index (FWI) reached 34, class High.
Where does this data come from?
From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Portugal (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 112.

How we know this
  • Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
  • The official perimeter has no end date: the end is the last day with VIIRS detections inside the perimeter before a gap of more than 10 days (150 days at most), so it is approximate. 2 Suomi-NPP VIIRS detections on those dates.
  • Compared with ICNF: 100 official ha against 105 ha of perimeter; they agree within 25%.
  • Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
  • Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2025, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.

How we build fire pages: methodology ›

Where this data comes from

The perimeter and land cover come from the Copernicus European Forest Fire Information System (EFFIS), measured on MODIS and Sentinel-2 imagery and published under CC BY 4.0. 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 ADM3 (CC0 1.0 Universal (CC0 1.0) Public Domain Dedication). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ slightly from each country’s official figure.
