Cualedro fire, July 2025 Cualedro

Out · last detection 24 Jul 2025, 02:45 UTC

The fire started on 23 July 2025 in Cualedro, Spain, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 145 hectares from satellite imagery, spread across a single municipality.

We are reviewing this page: some of its data look inconsistent (the place, the dates or the area), so treat them with caution.

The power measured by the satellite is low (1.2 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

It had gone 2 days without rain (1 mm or more) when it started.

This area had burned before

52% of the perimeter overlaps earlier fires recorded since 2016: 28 ha in 2016, 18 ha in 2019, 41 ha in 2022, 1 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 76 ha that had burned before.

Frequently asked questions

How long did the Cualedro fire last?
Copernicus dates it between 23 July 2025 and 24 July 2025: 2 days between the first and last image with fire.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 145 hectares (1.4 km²). Official national figures may differ.
Which municipalities burned?
The fire only entered Cualedro (5 ha, 0.0 %).
Did the fire reach a town?
The closest fire to a town centre came within 9.9 km of Cualedro. 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 26.6 °C, humidity dropped to 35 % and gusts hit 49 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 Spain (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.

Emergency number: 112

Satellite cross-check

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.

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.

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 4.0 International (CC BY 4.0)). 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.
