Chyhyryn fire, April 2025 Чигиринський район · Chyhyryn, Hlobyne
The fire started on 25 April 2025 in Chyhyryn, Ukraine, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 151 hectares from satellite imagery, spread across 2 municipalities.
It is the 24th largest in Cherkasy Oblast since 2016 (of 28 with a page). Number 891 in Ukraine in 2025, of 1359.
The power measured by the satellite is low (4.0 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

The smoke
CAMS · CopernicusOn 24 April 2025 the air beside the fire reached 13 µg/m³ of PM2.5, but no daily average passed the WHO guideline (15).

Frequently asked questions
- How long did the Chyhyryn fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 25 April 2025 to 26 April 2025 (2 days). The perimeter dates it from 26 April 2025 to 26 April 2025.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 151 hectares (1.5 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Chyhyryn (149 ha, 0.1 %); Hlobyne (3 ha, 0.0 %).
- Did the fire reach a town?
- The fire came within 19.8 km of the centre of Hlobyne, the closest of the areas it touched. 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 16.7 °C, humidity dropped to 45 % and gusts hit 50 km/h. The fire danger index (FWI) reached 12, class Moderate.
- 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.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 26 April 2025 to 26 April 2025. 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.
