Montalegre fire, July 2026 Cabril

Out · last detection 7 Jul 2026, 13:53 UTC

The fire started on 1 July 2026 in Cabril, Portugal, and satellites saw it burning for 7 days. Copernicus mapped a burnt perimeter of 161 hectares from satellite imagery, spread across a single municipality. According to ICNF, the largest of the 3 recorded fires was detected on 6 July 2026 at 20:58 and declared extinguished on 8 July 2026.

It is the 37th largest in Montalegre since 2016 (of 64 with a page). Number 57 in Portugal in 2026, of 86.

The power measured by the satellite is low (17.7 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Official record

Complex of 3 fires according to ICNF

According to ICNF, 3 fires started inside this perimeter on these dates, totalling 189 ha (the satellite measured 161 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.

On 9 July 2026 the air beside the fire reached 178 µg/m³ of PM2.5. That day averaged 56: 3.7 times the WHO daily guideline (15).

Frequently asked questions

How long did the Montalegre fire last?
The official perimeter only gives the start date (6 July 2026). The end comes from the heat detections inside the perimeter: it burned until 7 July 2026 (7 days from 1 July 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 3 recorded fires was detected on 6 July 2026 at 20:58 and declared extinguished on 8 July 2026.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 161 hectares (1.6 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Cabril (161 ha, 2.1 %).
Did the fire reach a town?
The fire started in Cabril and came within 2.4 km of its centre. 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.
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.

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. 13 Suomi-NPP VIIRS detections on those dates.
  • Compared with ICNF: 189 official ha against 161 ha of perimeter; they agree within 25%.

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.
