It had gone 8 days without rain (1 mm or more) when it started. Rain came after the fire: 2.1 mm on 10 Sept.

This area had burned before

53% of the perimeter overlaps earlier fires recorded since 2016: 675 ha in 2016, 283 ha in 2020, 67 ha in 2021, 582 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 1,020 ha that had burned before.

How big is it?

Frequently asked questions

How long did the Glamoč fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 5 September 2026 to 9 September 2026 (5 days). The perimeter dates it from 5 September 2026 to 5 September 2026.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 1,928 hectares (19.3 km²). Official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Glamoč (1,262 ha, 1.2 %); Drvar (668 ha, 1.3 %).
What was the weather like?
During the fire the temperature reached 28.9 °C, humidity dropped to 27 % and gusts hit 40 km/h. The fire danger index (FWI) reached 27, class 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.

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.

How we know this
  • Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
  • Dates adjusted with the VIIRS detections inside the perimeter, which said 5 September 2026 to 5 September 2026. 92 Suomi-NPP VIIRS detections on those dates.
  • We have not matched this page with any official record.
  • Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.

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.
