Bilozerka fire, 1 July 2025 Білозерський район · Bilozerka, Oleshky
The fire started on 1 July 2025 in Bilozerka, Ukraine, and satellites saw it burning for 3 days. Copernicus mapped a burnt perimeter of 115 hectares from satellite imagery, spread across 2 municipalities.
It is the 991th largest in Kherson Oblast since 2016 (of 1103 with a page). Number 1170 in Ukraine in 2025, of 1359.
The power measured by the satellite is low (17.0 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 2 days without rain (1 mm or more) when it started. Rain came after the fire: 1.1 mm on 5 Jul.
This area had burned before
36% of the perimeter overlaps earlier fires recorded since 2016: 41 ha in 2024.

The smoke
CAMS · CopernicusOn 6 July 2025 the air beside the fire reached 26 µg/m³ of PM2.5, but no daily average passed the WHO guideline (15).

Frequently asked questions
- How long did the Bilozerka fire last?
- Copernicus dates it between 1 July 2025 and 3 July 2025: 3 days between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 115 hectares (1.2 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Bilozerka (102 ha, 0.1 %); Oleshky (13 ha, 0.0 %).
- Did the fire reach a town?
- The closest fire to a town centre came within 19.1 km of Oleshky. 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 29.6 °C, humidity dropped to 25 % and gusts hit 44 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.

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
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.
