Stolac fire, June 2026 Mostar, Stolac, Berkovići
The fire started on 17 June 2026 in Stolac, Bosnia & Herzegovina, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 823 hectares from satellite imagery, spread across 3 municipalities.
It is the 73th largest in Federation of Bosnia and Herzegovina since 2016 (of 520 with a page). Number 16 in Bosnia & Herzegovina in 2026, of 94.
The power measured by the satellite is low (11.5 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: 3.2 mm on 22 Jun.
This area had burned before
85% of the perimeter overlaps earlier fires recorded since 2016: 287 ha in 2016, 253 ha in 2017, 170 ha in 2020, 530 ha in 2021, 2 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 701 ha that had burned before.

Frequently asked questions
- How long did the Stolac fire last?
- Copernicus dates it between 17 June 2026 and 17 June 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 823 hectares (8.2 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 3 municipalities: Mostar (316 ha, 0.3 %); Stolac (301 ha, 1.3 %); Berkovići (208 ha, 0.7 %).
- What was the weather like?
- During the fire the temperature reached 31.1 °C, humidity dropped to 34 % and gusts hit 29 km/h. The fire danger index (FWI) reached 17, 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.
