We have the Copernicus perimeter for this fire, but the VIIRS sensors did not capture it in enough detail: no day-by-day evolution, but the split by municipality is there.

According to EGIF (MITECO), this fire started on 24 June 2017 and burned 607 ha (the satellite measured 931 ha). The two figures differ a lot, so these may not be exactly the same fire: take them as nearby records.

First rain (1 mm or more) after it ended: 1.8 mm on 12 Jul.
It was 3.2 times larger than the median of its twins and lasted 1 day, against 2 days.
Only 8 of its 28 twins burned more. The weather on the first day does not explain everything: the wind in the following days, the fuel and the firefighting also count. In 13 of 28, 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 3.5 mm.

It was considered over on 24 Jun, and on 28 Jun 1.2 mm fell. We do not know whether the rain or the firefighters put it out. Twins with rain when they ended: 15 of 28, with a median of 3.5 mm.

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 June 2017 the air beside the fire reached 28 µg/m³ of PM2.5. That day averaged 19: 1.3 times the WHO daily guideline (15).

Copernicus dates it between 24 June 2017 and 24 June 2017: 1 day between the first and last image with fire.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 931 hectares (9.3 km²). Official national figures may differ.
Which municipalities burned?
The fire entered 2 municipalities: Guijo de Coria (611 ha, 8.2 %); Calzadilla (321 ha, 4.2 %).
Did the fire reach a town?
The fire came within 0.5 km of the centre of Calzadilla, the closest of the areas it touched. 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 32.9 °C, humidity dropped to 22 % and gusts hit 38 km/h. The fire danger index (FWI) reached 35, 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.
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: 28. Their median duration was 2 days and their median area 288 ha; 29 % went past 1,000 ha. Only 8 of its 28 twins burned more. The weather on the first day does not explain everything: the wind in the following days, the fuel and the firefighting also count. In 13 of 28, 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 3.5 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.
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.

Perimeter: EFFIS (Copernicus), mapped on satellite imagery.
Dates from the perimeter: the VIIRS detections inside it did not change them. No Suomi-NPP VIIRS detections on those dates.
Compared with EGIF (MITECO): 607 official ha against 931 ha of perimeter; similar, but with reservations.
Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
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.
