The smoke
CAMS · CopernicusOn 18 August 2025 the air beside the fire reached 93 µg/m³ of PM2.5. That day averaged 55: 3.6 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Aliseda fire last?
- Copernicus dates it between 15 August 2025 and 18 August 2025: 4 days between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 3,739 hectares (37.4 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Cáceres (3,727 ha, 2.1 %); Aliseda (16 ha, 0.2 %).
- Did the fire reach a town?
- The fire started in Aliseda and came within 6.4 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.
- What was the weather like?
- During the fire the temperature reached 40.9 °C, humidity dropped to 11 % and gusts hit 36 km/h. The fire danger index (FWI) reached 51, class Extreme.
- Where does this data come from?
- From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Spain (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.
Report an error
How we know this
- Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
- Dates from the perimeter: the VIIRS detections inside it did not change them. 96 Suomi-NPP VIIRS detections on those dates.
- We have not matched this page with any official record.
- Checked against news and agencies: 4 confirmed sources.
- Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
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 (Creative Commons Attribution 4.0 International (CC BY 4.0)). 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.
