How long did the Yasynuvata fire last?

The official perimeter only gives the start date (16 July 2026). The end comes from the heat detections inside the perimeter: it burned until 23 August 2026 (39 days from 16 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 245 hectares (2.4 km²). Official national figures may differ.

Which municipalities burned?

The fire only entered Yasynuvata (245 ha, 0.2 %).

What was the weather like?

During the fire the temperature reached 35.2 °C, humidity dropped to 15 % and gusts hit 48 km/h. The fire danger index (FWI) reached 47, 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.

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. 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.

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.
