Salemi fire, June 2026 Trapani, Salemi, Calatafimi-Segesta
The fire started on 13 June 2026 in Salemi, Italy, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 1,226 hectares from satellite imagery, spread across 3 municipalities.
It is the 6th largest in Trapani since 2016 (of 68 with a page). Number 18 in Italy in 2026, of 231.

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 13 days without rain (1 mm or more) when it started.
This area had burned before
83% of the perimeter overlaps earlier fires recorded since 2016: 802 ha in 2020, 351 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 1,020 ha that had burned before.

Frequently asked questions
- How long did the Salemi fire last?
- Copernicus dates it between 13 June 2026 and 13 June 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 1,226 hectares (12.3 km²). Official national figures may differ.
- Which municipalities burned?
- The fire entered 3 municipalities: Trapani (673 ha, 3.7 %); Salemi (522 ha, 2.9 %); Calatafimi-Segesta (32 ha, 0.2 %).
- Did the fire reach a town?
- The closest fire to a town centre came within 4.2 km of Calatafimi-Segesta. 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 25.3 °C, humidity dropped to 38 % and gusts hit 40 km/h. The fire danger index (FWI) reached 26, 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.
