It had gone 16 days without rain (1 mm or more) when it started. Rain came after the fire: 1.6 mm on 13 Aug.

This area had burned before

39% of the perimeter overlaps earlier fires recorded since 2016: 120 ha in 2017, 73 ha in 2019, 228 ha in 2020, 242 ha in 2021, 286 ha in 2022, 741 ha in 2023, 9 ha in 2024, 634 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 1,390 ha that had burned before.

How big is it?

Frequently asked questions

How long did the Butera fire last?
The official perimeter only gives the start date (18 July 2026). The end comes from the heat detections inside the perimeter: it burned until 7 August 2026 (21 days from 18 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 3,558 hectares (35.6 km²). Official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Butera (3,533 ha, 12 %); Gela (31 ha, 0.1 %).
Did the fire reach a town?
The fire started in Butera and reached its centre: the point marking it was inside the burnt area or less than 500 metres from it. That does not mean houses burned.
What was the weather like?
During the fire the temperature reached 42.7 °C, humidity dropped to 18 % and gusts hit 46 km/h. The fire danger index (FWI) reached 52, class Extreme.
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.

How we know this
  • Perimeter: EFFIS (Copernicus), mapped on satellite imagery; 2 polygons grouped in this page.
  • 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. 112 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.

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.
