It had gone 0 days without rain (1 mm or more) when it started. Rain came after the fire: 5.3 mm on 6 Sept.

This area had burned before

100% of the perimeter overlaps earlier fires recorded since 2016: 137 ha in 2022, 139 ha in 2024, 72 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 139 ha that had burned before.

Frequently asked questions

How long did the Bakhmut fire last?
Copernicus dates it between 3 July 2026 and 3 July 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 139 hectares (1.4 km²). Official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Bakhmut (138 ha, 0.1 %); Perevalsk (1 ha, 0.0 %).
Did the fire reach a town?
The closest fire to a town centre came within 30.7 km of Perevalsk. That is the distance to the perimeter or nearest hotspot; it does not mean it entered the houses.
What was the weather like?
During the fire the temperature reached 33.8 °C, humidity dropped to 16 % and gusts hit 49 km/h. The fire danger index (FWI) reached 36, class High.
Where does this data come from?
From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Ukraine (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 ADM2 (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.
