Bilopillia fire, 27 September 2024 Білопільський район · Bilopillia
Out · last detection 1 Oct 2024, 09:56 UTC
The fire started on 27 September 2024 in Bilopillia, Ukraine, and satellites saw it burning for 5 days. Copernicus mapped a burnt perimeter of 101 hectares from satellite imagery, spread across a single municipality.
It is the 124th largest in Sumy Oblast since 2016 (of 129 with a page). Number 2045 in Ukraine in 2024, of 2092.
The power measured by the satellite is low (10.8 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

How a twin is chosen
- Same area: fires that have already ended, less than 250 km from this one, since 2020.
- Same start: we compare the FWI on the first day, the minimum humidity that day and the run of days without rain before it. The slider sets how much they may differ.
- Only pages with final weather data (ERA5 reanalysis) calculated in the same way as this fire’s; agricultural and grass burns and pages with data under review are left out.
- Fires burning at the same time as this one (a week before or after) are left out: they share the same spell of weather and do not count as a precedent.
- They are sorted by similarity, and the outlines of the first five are drawn.

Frequently asked questions
- How long did the Bilopillia fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 27 September 2024 to 1 October 2024 (5 days). The perimeter dates it from 27 September 2024 to 28 September 2024.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 101 hectares (1.0 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Bilopillia (101 ha, 0.1 %).
- Did the fire reach a town?
- The fire started in Bilopillia and came within 29.0 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 28.2 °C, humidity dropped to 23 % and gusts hit 56 km/h. The fire danger index (FWI) reached 64, class Extreme.
- 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
- Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 27 September 2024 to 28 September 2024. 4 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.
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.
