The smoke
CAMS · CopernicusOn 4 August 2026 the air beside the fire reached 57 µg/m³ of PM2.5. That day averaged 33: 2.2 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Trebinje fire last?
- Copernicus dates it between 31 July 2026 and 31 July 2026: 1 day between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 1,298 hectares (13.0 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Trebinje (1,120 ha, 1.3 %); Ravno (176 ha, 0.6 %).
- What was the weather like?
- During the fire the temperature reached 31.9 °C, humidity dropped to 43 % and gusts hit 17 km/h. The fire danger index (FWI) reached 12, class Moderate.
- 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.

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 (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.
