Bilozerka fire, 21 June 2026 Білозерський район · Ukraine
The fire started on 21 June 2026 in Bilozerka, Ukraine, and satellites saw it burning for 3 days. Copernicus mapped a burnt perimeter of 619 hectares from satellite imagery, spread across a single municipality.
It is the 153th largest in Kherson Oblast since 2016 (of 1103 with a page). Number 90 in Ukraine in 2026, of 984.
The power measured by the satellite is low (9.6 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 9 days without rain (1 mm or more) when it started.
This area had burned before
61% of the perimeter overlaps earlier fires recorded since 2016: 201 ha in 2022, 291 ha in 2023, 105 ha in 2024, 9 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 377 ha that had burned before.

People and buildings inside the perimeter
GHSL 2025Inside the perimeter there were about 1.0 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.

The smoke
CAMS · CopernicusOn 24 June 2026 the air beside the fire reached 7 µg/m³ of PM2.5, but no daily average passed the WHO guideline (15).
Particles from the Copernicus CAMS model at the centre of the perimeter; these are not measurements in each town. The pale bar is the worst hour, the solid one the daily average.

Frequently asked questions
- How long did the Bilozerka fire last?
- The official perimeter only gives the start date (21 June 2026). The end comes from the heat detections inside the perimeter: it burned until 23 June 2026 (3 days from 21 June 2026), the last day with detections before more than 10 days in a row without any, so it is approximate.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 619 hectares (6.2 km²). Official national figures may differ.
- What was the weather like?
- During the fire the temperature reached 31.5 °C, humidity dropped to 33 % and gusts hit 38 km/h. The fire danger index (FWI) reached 27, 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.

How we know this
- Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
- The official perimeter has no end date: the end is the last day with VIIRS detections inside the perimeter before a gap of more than 10 days (150 days at most), so it is approximate. 14 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.
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.
