Abrantes fire, July 2020 Fontes, Carvalhal
The fire started on 22 July 2020 in Fontes, Portugal, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 212 hectares from satellite imagery, spread across 2 municipalities. According to ICNF, it was detected on 22 July 2020 at 13:27 and declared extinguished on 22 July 2020.
Number 39 in Portugal in 2020, of 67.
The power measured by the satellite is low (10.3 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

The smoke
CAMS · CopernicusOn 23 July 2020 the air beside the fire reached 23 µg/m³ of PM2.5, but no daily average passed the WHO guideline (15).

Frequently asked questions
- How long did the Abrantes fire last?
- Copernicus dates it between 22 July 2020 and 22 July 2020: 1 day between the first and last image with fire. According to ICNF, it was detected on 22 July 2020 at 13:27 and declared extinguished on 22 July 2020.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 212 hectares (2.1 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Fontes (137 ha, 4.8 %); Carvalhal (75 ha, 4.3 %).
- Did the fire reach a town?
- The closest fire to a town centre came within 0.5 km of Fontes. That is the distance to the perimeter or nearest hotspot; it does not mean it entered the houses.
- What was the weather like?
- During the fire the temperature reached 34.0 °C, humidity dropped to 31 % and gusts hit 41 km/h. The fire danger index (FWI) reached 37, 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.

Satellite cross-check
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.

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.
