Sanski Most fire, August 2026 Oštra Luka, Sanski Most
The fire started on 14 August 2026 in Sanski Most, Bosnia & Herzegovina, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 271 hectares from satellite imagery, spread across 2 municipalities.
It is the 226th largest in Federation of Bosnia and Herzegovina since 2016 (of 520 with a page). Number 40 in Bosnia & Herzegovina in 2026, of 94.
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.

The smoke
CAMS · CopernicusOn 19 August 2026 the air beside the fire reached 23 µg/m³ of PM2.5. That day averaged 17: 1.1 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Sanski Most fire last?
- Copernicus dates it between 14 August 2026 and 14 August 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 271 hectares (2.7 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Oštra Luka (147 ha, 0.6 %); Sanski Most (125 ha, 0.2 %).
- What was the weather like?
- During the fire the temperature reached 38.7 °C, humidity dropped to 20 % and gusts hit 45 km/h. The fire danger index (FWI) reached 41, class Very 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.

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.
