Salah Bouchaour fire, July 2026 صالح بوالشعور · Salah Bouchaour

Out · last detection 20 Jul 2026, 13:06 UTC

The fire started on 19 July 2026 in Salah Bouchaour, Algeria, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 172 hectares from satellite imagery, spread across a single municipality.

It is the 68th largest in Skikda since 2016 (of 102 with a page). Number 154 in Algeria in 2026, of 197.

The power measured by the satellite is low (22.9 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Its twins: fires that started in the same weather

It started with an FWI of 58.3, a minimum humidity of 20% and 33 days without rain. Fires in the area that started in weather like this since 2016: 21.

How a twin is chosen

  • Same area: fires that have already ended, less than 250 km from this one, since 2016.
  • Same start: we compare the FWI on the first day, the minimum humidity that day and the run of days without rain before it. The slider sets how much they may differ.
  • Only pages with final weather data (ERA5 reanalysis) calculated in the same way as this fire’s; agricultural and grass burns and pages with data under review are left out.
  • Fires burning at the same time as this one (a week before or after) are left out: they share the same spell of weather and do not count as a precedent.
  • They are sorted by similarity, and the outlines of the first five are drawn.

On 22 July 2026 the air beside the fire reached 48 µg/m³ of PM2.5. That day averaged 34: 2.3 times the WHO daily guideline (15).

Frequently asked questions

How long did the Salah Bouchaour fire last?
The official perimeter only gives the start date (19 July 2026). The end comes from the heat detections inside the perimeter: it burned until 20 July 2026 (2 days from 19 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 172 hectares (1.7 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Salah Bouchaour (172 ha, 1.8 %).
Did the fire reach a town?
The fire started in Salah Bouchaour and came within 6.8 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 42.2 °C, humidity dropped to 20 % and gusts hit 31 km/h. The fire danger index (FWI) reached 58, class Extreme.
Where does this data come from?
From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Algeria (geoBoundaries). It is not an official report.
How did the fires that started in similar weather in this area end?
Fires less than 250 km away that started since 2016 with a similar FWI, humidity and dry spell: 21. Their median duration was 2 days and their median area 229 ha; 19 % went past 1,000 ha. In 7 of 21, not even 1 mm fell in the ten days after the end: they went out without rain. In the rest, the first rainy day brought a median of 2.0 mm.

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. 7 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 ADM3 (Creative Commons Attribution-ShareAlike 2.0). 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.
