It had gone 31 days without rain (1 mm or more) when it started.

This area had burned before

99% of the perimeter overlaps earlier fires recorded since 2016: 368 ha in 2016, 141 ha in 2017, 467 ha in 2019, 629 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 629 ha that had burned before.

How big is it?

Burnt area inside each municipality, from crossing the official perimeter with administrative boundaries. The distance runs from the point marking the centre of each area to the nearest fire: staying a kilometre away does not mean it reached the houses.

Frequently asked questions

How long did the Cherven Bryag fire last?
The official perimeter only gives the start date (23 August 2026). The end comes from the heat detections inside the perimeter: it burned until 24 August 2026 (2 days from 23 August 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 637 hectares (6.4 km²). Official national figures may differ.
Which municipalities burned?
The fire entered 3 municipalities: Cherven Bryag (418 ha, 1.0 %); Roman (161 ha, 0.5 %); Byala Slatina (57 ha, 0.1 %).
Did the fire reach a town?
The fire came within 9.2 km of the centre of Roman, the closest of the areas it touched. 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 33.7 °C, humidity dropped to 25 % and gusts hit 30 km/h. The fire danger index (FWI) reached 42, class Very high.
Where does this data come from?
From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Bulgaria (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.

What do you think is wrong?

We will only use your email to reply about this report. Privacy. This is not an emergency service: if there is a fire now, call 112.

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. 16 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.
