Burnt area inside each municipality, from crossing the official 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.

Inside the perimeter there was no noticeable 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.

Official record

Complex of 2 fires according to ICNF

According to ICNF, 2 fires started inside this perimeter on these dates, totalling 2,135 ha (the satellite measured 2,042 ha).

ICNF records each fire that started at a different time or place separately; the satellite sees a single burned area, so this page groups them together. The numbers on the map show where each one started.

Frequently asked questions

How long did the Vinhais fire last?
The official perimeter only gives the start date (15 August 2026). The end comes from the heat detections inside the perimeter: it burned until 24 August 2026 (10 days from 15 August 2026), the last day with detections before more than 10 days in a row without any, so it is approximate. According to ICNF, the largest of the 2 recorded fires was detected on 15 August 2026 at 04:36 and declared extinguished on 15 August 2026.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 2,042 hectares (20.4 km²). Official national figures may differ.
Which municipalities burned?
The fire entered 5 municipalities: Soeira, Fresulfe e Mofreita (841 ha, 18 %); Travanca e Santa Cruz (650 ha, 28 %); Moimenta e Montouto (462 ha, 11 %); Tuizelo (77 ha, 2.5 %); Vilar de Ossos (1 ha, 0.0 %).
Did the fire reach a town?
The fire came within 1.4 km of the centre of Travanca e Santa Cruz, 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 33.1 °C, humidity dropped to 23 % and gusts hit 59 km/h. The fire danger index (FWI) reached 31, 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. 31 Suomi-NPP VIIRS detections on those dates.
  • Compared with ICNF: 2,135 official ha against 2,042 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.
