How long did the Bilozerka fire last?

According to the heat detections seen by satellite inside the perimeter, it burned from 16 July 2025 to 23 July 2025 (8 days). The perimeter dates it from 17 July 2025 to 20 July 2025.

How much area did it burn?

The perimeter Copernicus measured from satellite imagery is 961 hectares (9.6 km²). Official national figures may differ.

Which municipalities burned?

The fire only entered Bilozerka (961 ha, 0.6 %).

Did the fire reach a town?

The fire started in Bilozerka and came within 12.4 km of its centre. That is the distance from the perimeter, or the nearest hotspot, to the point marking the centre; it does not mean it entered the houses.

What was the weather like?

During the fire the temperature reached 34.7 °C, humidity dropped to 22 % and gusts hit 52 km/h. The fire danger index (FWI) reached 45, class Very 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.

Out · last detection 23 Jul 2025, 23:21 UTC

The fire started on 16 July 2025 in Bilozerka, Ukraine, and satellites saw it burning for 8 days. Copernicus mapped a burnt perimeter of 961 hectares from satellite imagery, spread across a single municipality.

It is the 96th largest in Kherson Oblast since 2016 (of 1103 with a page). Number 64 in Ukraine in 2025, of 1359.

The power measured by the satellite is low (7.5 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Inside the perimeter there were about 1.5 hectares of built-up land and almost nobody lived there (GHSL 2025, satellite-based estimate).

This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned. The GHSL 2025 epoch is a projection made from 2020 and earlier data.

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.

How we know this

Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
Dates adjusted with the VIIRS detections inside the perimeter, which said 17 July 2025 to 20 July 2025. 8 Suomi-NPP VIIRS detections on those dates.
We have not matched this page with any official record.
Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2025, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.

How we build fire pages: methodology ›

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.
