Hermisende fire, September 2025 Hermisende
The fire started on 6 September 2025 in Hermisende, Spain, and satellites saw it burning for 3 days. Copernicus mapped a burnt perimeter of 470 hectares from satellite imagery, spread across a single municipality.
It is the 15th largest in Zamora since 2016 (of 45 with a page). Number 64 in Spain in 2025, of 158.
We have the Copernicus perimeter for this fire, but not yet its hotspots: NASA publishes the yearly hotspot archive only once the year closes. The page picks it up automatically when it is available.

Burnt area inside each municipality, from crossing the official perimeter with administrative boundaries. The distance is from the town centre to the nearest fire: staying a kilometre away does not mean it reached the houses.

The smoke
CAMS · CopernicusOn 8 September 2025 the air beside the fire reached 55 µg/m³ of PM2.5, but no daily average passed the WHO guideline (15).
Particles from the Copernicus CAMS model at the centre of the perimeter; these are not measurements in each town. The pale bar is the worst hour, the solid one the daily average.

Frequently asked questions
- How long did the Hermisende fire last?
- Copernicus dates it between 6 September 2025 and 8 September 2025: 3 days between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 470 hectares (4.7 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Hermisende (435 ha, 4.0 %).
- Did the fire reach a town?
- The closest fire to a town centre came within 7.0 km of Hermisende. 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 27.1 °C, humidity dropped to 28 % and gusts hit 58 km/h. The fire danger index (FWI) reached 36, class High.
- 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.
Emergency number: 112

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 (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.
