Kalanchak fire, 3 July 2026 Каланчацький район · Kalanchak
The fire started on 3 July 2026 in Kalanchak, Ukraine, and satellites saw it burning for 5 days. Copernicus mapped a burnt perimeter of 1,279 hectares from satellite imagery, spread across a single municipality.
It is the 64th largest in Kherson Oblast since 2016 (of 1103 with a page). Number 33 in Ukraine in 2026, of 984.

This area had burned before
38% of the perimeter overlaps earlier fires recorded since 2016: 405 ha in 2023, 142 ha in 2024, 20 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 491 ha that had burned before.

The smoke
CAMS · CopernicusOn 4 July 2026 the air beside the fire reached 12 µg/m³ of PM2.5, but no daily average passed the WHO guideline (15).

Frequently asked questions
- How long did the Kalanchak fire last?
- The official perimeter only gives the start date (3 July 2026). The end comes from the heat detections inside the perimeter: it burned until 7 July 2026 (5 days from 3 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 1,279 hectares (12.8 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Kalanchak (1,279 ha, 1.2 %).
- Did the fire reach a town?
- The fire started in Kalanchak and came within 19.1 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.
- 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.
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. 42 Suomi-NPP VIIRS detections on those dates.
- We have not matched this page with any official record.
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.
