Sanski Most fire, March 2025 Sanski Most
The fire started on 7 March 2025 in Sanski Most, Bosnia & Herzegovina, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 158 hectares from satellite imagery, spread across a single municipality.
It is the 372th largest in Federation of Bosnia and Herzegovina since 2016 (of 520 with a page). Number 44 in Bosnia & Herzegovina in 2025, of 65.
The power measured by the satellite is low (7.7 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 5 days without rain (1 mm or more) when it started. Rain came after the fire: 13.3 mm on 11 Mar.
This area had burned before
68% of the perimeter overlaps earlier fires recorded since 2016: 87 ha in 2020, 100 ha in 2022. Part of it burned more than once, so the yearly figures add up to more than the 107 ha that had burned before.

ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

CAMS · CopernicusOn 8 March 2025 the air beside the fire reached 45 µg/m³ of PM2.5. That day averaged 31: 2.1 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Sanski Most fire last?
- Copernicus dates it between 7 March 2025 and 8 March 2025: 2 days between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 158 hectares (1.6 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Sanski Most (158 ha, 0.2 %).
- What was the weather like?
- During the fire the temperature reached 20.4 °C, humidity dropped to 24 % and gusts hit 19 km/h. The fire danger index (FWI) reached 5, class 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.

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.
