It had gone 8 days without rain (1 mm or more) when it started. Rain came after the fire: 4.0 mm on 15 Jun.

This area had burned before

56% of the perimeter overlaps earlier fires recorded since 2016: 48 ha in 2021, 1,774 ha in 2023, 535 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 2,035 ha that had burned before.

Inside the perimeter there was no noticeable 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.

Its twins: fires that started in the same weather

It started with an FWI of 15.5, a minimum humidity of 38% and 8 days without rain. Fires in the area that started in weather like this since 2017: 67.

It was 19.2 times larger than the median of its twins and lasted 6 days, against 5 days.

None of its 67 twins burned more. The weather on the first day does not explain everything: the wind in the following days, the fuel and the firefighting also count. In 11 of 67, not even 1 mm fell in the ten days after the end: they went out without rain. In the rest, the first rainy day brought a median of 3.7 mm.

How a twin is chosen

  • Same area: fires that have already ended, less than 250 km from this one, since 2017.
  • 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 Holo Prystan fire last?
According to the heat detections seen by satellite inside the perimeter, it burned from 6 June 2025 to 11 June 2025 (6 days). The perimeter dates it from 10 June 2025 to 11 June 2025.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 3,629 hectares (36.3 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Holo Prystan (55 ha, 0.0 %).
Did the fire reach a town?
The fire started in Holo Prystan and came within 52.8 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 30.9 °C, humidity dropped to 29 % and gusts hit 47 km/h. The fire danger index (FWI) reached 28, 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.
How did the fires that started in similar weather in this area end?
Fires less than 250 km away that started since 2017 with a similar FWI, humidity and dry spell: 67. Their median duration was 5 days and their median area 189 ha; 7 % went past 1,000 ha. None of its 67 twins burned more. The weather on the first day does not explain everything: the wind in the following days, the fuel and the firefighting also count. In 11 of 67, not even 1 mm fell in the ten days after the end: they went out without rain. In the rest, the first rainy day brought a median of 3.7 mm.

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 10 June 2025 to 11 June 2025. 84 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.
