How long did the Chaplynka fire last?

The official perimeter only gives the start date (11 July 2026). The end comes from the heat detections inside the perimeter: it burned until 16 August 2026 (37 days from 11 July 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 391 hectares (3.9 km²). Official national figures may differ.

Which municipalities burned?

The fire only entered Chaplynka (392 ha, 0.2 %).

Did the fire reach a town?

The fire started in Chaplynka and came within 33.8 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 36.7 °C, humidity dropped to 24 % and gusts hit 56 km/h. The fire danger index (FWI) reached 45, class Very 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.

Out · last detection 16 Aug 2026, 11:21 UTC

The fire started on 11 July 2026 in Chaplynka, Ukraine, and satellites saw it burning for 37 days. Copernicus mapped a burnt perimeter of 391 hectares from satellite imagery, spread across a single municipality.

It is the 287th largest in Kherson Oblast since 2016 (of 1103 with a page). Number 202 in Ukraine in 2026, of 984.

The power measured by the satellite is low (21.9 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

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. 5 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.
