Doboj fire, 1 October 2026 Doboj, Modriča, Odžak
Satellites first detected fire on 1 October 2026 in Doboj, Bosnia & Herzegovina. It has been active for 8 days, with 17 heat detections and an area with fire of about 210 hectares rebuilt from them, spread across 5 municipalities.
The power measured by the satellite is low (5.2 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.
Copernicus has not yet published the burnt perimeter, which takes a few days to measure on satellite imagery. For now the area is the one rebuilt from heat detections (about 14 hectares per pixel). When the perimeter arrives, this page picks it up on its own and keeps the same address.

Area with fire inside each municipality, rebuilt from heat detections (about 14 hectares per VIIRS pixel). An estimate until the official perimeter arrives. The distance is from the town centre to the nearest fire: staying a kilometre away does not mean it reached the houses.
The weather day by day
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.

The smoke
CAMS · CopernicusOn 6 October 2026 the air beside the fire reached 56 µg/m³ of PM2.5. That day averaged 37: 2.5 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Doboj fire last?
- According to the heat detections seen by satellite, it burned from 1 October 2026 to 8 October 2026 (8 days between the first and the last detection). There is no perimeter yet to date it.
- How much area did it burn?
- There is no official perimeter yet. Heat detections rebuild about 210 hectares with fire (2.1 km²); Copernicus will publish the measured figure within days.
- Which municipalities burned?
- The fire entered 5 municipalities: Doboj (98 ha, 0.1 %); Modriča (70 ha, 0.2 %); Odžak (28 ha, 0.2 %); Vukosavlje (28 ha, 0.4 %); Šamac (0 ha, 0.0 %).
- Is the Doboj fire still active?
- No fire detections since 8 Oct 2026, 11:49 UTC. A lack of detections is not an official extinction.
- What was the weather like?
- During the fire the temperature reached 27.9 °C, humidity dropped to 29 % and gusts hit 36 km/h. The fire danger index (FWI) reached 20, class Moderate.
- 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.
