Trebinje fire, 6 July 2025 Trebinje
The fire started on 6 July 2025 in Trebinje, Bosnia & Herzegovina, and satellites saw it burning for 4 days. Copernicus mapped a burnt perimeter of 1,866 hectares from satellite imagery, spread across a single municipality.
It is the 22th largest in Republika Srpska since 2016 (of 391 with a page). Number 5 in Bosnia & Herzegovina in 2025, of 65.
The power measured by the satellite is low (17.1 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Where it burned
How it evolved, day by day
Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
The weather it burned in
It had gone 15 days without rain (1 mm or more) when it started.
This area had burned before
83% of the perimeter overlaps earlier fires recorded since 2016: 1,540 ha in 2016, 3 ha in 2020, 249 ha in 2022. Part of it burned more than once, so the yearly figures add up to more than the 1,543 ha that had burned before.

The smoke
CAMS · CopernicusOn 12 July 2025 the air beside the fire reached 21 µg/m³ of PM2.5, but no daily average passed the WHO guideline (15).

Frequently asked questions
- How long did the Trebinje fire last?
- Copernicus dates it between 6 July 2025 and 9 July 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 1,866 hectares (18.7 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Trebinje (1,867 ha, 2.1 %).
- What was the weather like?
- During the fire the temperature reached 29.1 °C, humidity dropped to 46 % and gusts hit 59 km/h. The fire danger index (FWI) reached 23, class High.
- Where does this data come from?
- From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Bosnia & Herzegovina (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.
Report an error
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 (Public Domain). 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.
