Holo Prystan fire, 15 August 2026 Скадовський район · Holo Prystan

Out · last detection 15 Aug 2026, 11:40 UTC

The fire started on 15 August 2026 in Holo Prystan, Ukraine, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 563 hectares from satellite imagery, spread across a single municipality.

It is the 175th largest in Kherson Oblast since 2016 (of 1102 with a page). Number 107 in Ukraine in 2026, of 984.

The power measured by the satellite is low (15.8 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

The weather it burned in

It had gone 17 days without rain (1 mm or more) when it started. Rain came after the fire: 1.6 mm on 19 Aug.

This area had burned before

26% of the perimeter overlaps earlier fires recorded since 2016: 13 ha in 2022, 116 ha in 2023, 2 ha in 2024, 64 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 145 ha that had burned before.

How big is it?

It burned the equivalent of 0.4% of the area of London (5.6 km² against 1,583 km²).

It was 1.9 times larger than the median of its twins and lasted 1 day, against 2 days.

Only 18 of its 71 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 24 of 71, 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 2.5 mm.

How a twin is chosen

  • Same area: fires that have already ended, less than 250 km from this one, since 2022.
  • 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?
The official perimeter only gives the start date (15 August 2026). The end comes from the heat detections inside the perimeter: it burned until 15 August 2026 (1 day from 15 August 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 563 hectares (5.6 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Holo Prystan (549 ha, 0.2 %).
Did the fire reach a town?
The fire started in Holo Prystan and came within 28.8 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 26.5 °C, humidity dropped to 32 % and gusts hit 28 km/h. The fire danger index (FWI) reached 26, 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 2022 with a similar FWI, humidity and dry spell: 71. Their median duration was 2 days and their median area 303 ha; 18 % went past 1,000 ha. Only 18 of its 71 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 24 of 71, 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 2.5 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.
  • 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. 38 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.

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.
