Novovorontsovka fire, 13 June 2026 Нововоронцовський район · Novovorontsovka

Out · last detection 3 Jul 2026, 00:20 UTC

The fire started on 13 June 2026 in Novovorontsovka, Ukraine, and satellites saw it burning for 21 days. Copernicus mapped a burnt perimeter of 821 hectares from satellite imagery, spread across a single municipality.

It is the 117th largest in Kherson Oblast since 2016 (of 1103 with a page). Number 62 in Ukraine in 2026, of 984.

The power measured by the satellite is low (13.0 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Built-up area9.6 ha
Residents≈ 350

Inside the perimeter there were about 9.6 hectares of built-up land and about 350 residents (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.

It was 3.8 times larger than the median of its twins and lasted 21 days, against 1 day.

Only 3 of its 34 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 8 of 34, 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 3.3 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 Novovorontsovka fire last?
The official perimeter only gives the start date (13 June 2026). The end comes from the heat detections inside the perimeter: it burned until 3 July 2026 (21 days from 13 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 821 hectares (8.2 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Novovorontsovka (819 ha, 0.7 %).
Did the fire reach a town?
The fire started in Novovorontsovka and came within 9.6 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 35.4 °C, humidity dropped to 24 % and gusts hit 51 km/h. The fire danger index (FWI) reached 34, 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: 34. Their median duration was 1 day and their median area 218 ha; 9 % went past 1,000 ha. Only 3 of its 34 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 8 of 34, 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 3.3 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. 22 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.
