Dobropillia fire, July 2026 Добропільський район · Ukraine
Satellites first detected fire on 31 July 2026 in Dobropillia, Ukraine. It was active for 54 days, with 89 heat detections and an area with fire of about 168 hectares rebuilt from them, spread across a single municipality.

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.

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 3 days without rain (1 mm or more) when it started. Rain came after the fire: 25.5 mm on 23 Sept.
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 19 September 2026 the air beside the fire reached 28 µg/m³ of PM2.5. That day averaged 16: 1.0 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Dobropillia fire last?
- According to the heat detections seen by satellite, it burned from 31 July 2026 to 22 September 2026 (54 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 168 hectares with fire (1.7 km²); Copernicus will publish the measured figure within days.
- What was the weather like?
- During the fire the temperature reached 26.8 °C, humidity dropped to 32 % and gusts hit 35 km/h. The fire danger index (FWI) reached 23, 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.

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.
Report an error
How we know this
- No perimeter yet: the area (≈ 168 ha) is estimated by counting VIIRS pixels with fire, about 14 ha each.
- Dates of the first and last VIIRS detection of the cluster. 89 Suomi-NPP VIIRS detections on those dates.
- 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 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.
