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 16 days without rain (1 mm or more) when it started. Rain came after the fire: 2.4 mm on 18 Aug.
This area had burned before
69% of the perimeter overlaps earlier fires recorded since 2016: 668 ha in 2017, 46 ha in 2019, 550 ha in 2020. Part of it burned more than once, so the yearly figures add up to more than the 850 ha that had burned before.

Frequently asked questions
- How long did the Bileća fire last?
- Copernicus dates it between 5 August 2021 and 11 August 2021: 7 days between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 1,239 hectares (12.4 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Nevesinje (1,118 ha, 1.2 %); Bileća (118 ha, 0.2 %).

- 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.
