Salemi fire, August 2026 Salemi
The fire started on 24 August 2026 in Salemi, Italy, and satellites saw it burning for 4 days. Copernicus mapped a burnt perimeter of 293 hectares from satellite imagery, spread across a single municipality.
It is the 24th largest in Trapani since 2016 (of 68 with a page). Number 73 in Italy in 2026, of 231.
The power measured by the satellite is low (25.6 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Where it burned
How it evolved, day by day
Fire radiative power detected each day, in megawatts, and number of hotspots. The magenta bar marks the peak day.
The weather it burned in
It had gone 25 days without rain (1 mm or more) when it started.
This area had burned before
80% of the perimeter overlaps earlier fires recorded since 2016: 36 ha in 2017, 82 ha in 2019, 7 ha in 2021, 220 ha in 2022, 130 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 235 ha that had burned before.

The smoke
CAMS · CopernicusOn 26 August 2026 the air beside the fire reached 28 µg/m³ of PM2.5. That day averaged 19: 1.3 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Salemi fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 24 August 2026 to 27 August 2026 (4 days). The perimeter dates it from 24 August 2026 to 24 August 2026.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 293 hectares (2.9 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Salemi (294 ha, 1.6 %).
- Did the fire reach a town?
- The closest fire to a town centre came within 4.9 km of Salemi. That is the distance to the perimeter or nearest hotspot; it does not mean it entered the houses.
- What was the weather like?
- During the fire the temperature reached 34.5 °C, humidity dropped to 37 % and gusts hit 42 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 Italy (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 ADM4 (Creative Commons Attribution 3.0 License). 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.
