Polgor fire, August 2026 Polgor, G
The fire started on 20 August 2026 in Polgor, Hungary, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 195 hectares from satellite imagery, spread across 2 municipalities.
It is the 6th largest in Hajdú-Bihar since 2016 (of 10 with a page). Number 3 in Hungary in 2026, of 6.
We have the Copernicus perimeter for this fire, but not yet its hotspots: NASA publishes the yearly hotspot archive only once the year closes. The page picks it up automatically when it is available.

The smoke
CAMS · CopernicusOn 20 August 2026 the air beside the fire reached 15 µg/m³ of PM2.5, but no daily average passed the WHO guideline (15).
Particles from the Copernicus CAMS model at the centre of the perimeter; these are not measurements in each town. The pale bar is the worst hour, the solid one the daily average.

Frequently asked questions
- How long did the Polgor fire last?
- Copernicus dates it between 20 August 2026 and 20 August 2026: 1 day between the first and last image with fire.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 195 hectares (2.0 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Polgor (173 ha, 1.8 %); G (22 ha, 0.3 %).
- What was the weather like?
- During the fire the temperature reached 36.2 °C, humidity dropped to 27 % and gusts hit 38 km/h. The fire danger index (FWI) reached 36, class High.
- Where does this data come from?
- From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Hungary (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.

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 ADM3 (Open Data Commons Open Database License 1.0). 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.
