Bileća fire, 4 March 2025 Bileća

Out · last detection 8 Mar 2025, 12:13 UTC

The fire started on 4 March 2025 in Bileća, Bosnia & Herzegovina, and satellites saw it burning for 4 days. Copernicus mapped a burnt perimeter of 1,092 hectares from satellite imagery, spread across a single municipality.

It is the 47th largest in Republika Srpska since 2016 (of 391 with a page). Number 8 in Bosnia & Herzegovina in 2025, of 65.

The power measured by the satellite is low (15.4 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

It had gone one day without rain (1 mm or more) when it started. Rain came after the fire: 16.3 mm on 10 Mar.

This area had burned before

72% of the perimeter overlaps earlier fires recorded since 2016: 380 ha in 2017, 343 ha in 2019, 148 ha in 2020, 72 ha in 2021, 189 ha in 2022, 66 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 787 ha that had burned before.

Frequently asked questions

How long did the Bileća fire last?
Copernicus dates it between 4 March 2025 and 7 March 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 1,092 hectares (10.9 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Bileća (1,094 ha, 1.7 %).
What was the weather like?
During the fire the temperature reached 17.0 °C, humidity dropped to 24 % and gusts hit 26 km/h. The fire danger index (FWI) reached 4, class Very low.
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.

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.
