Almonaster la Real fire, August 2018 Almonaster la Real
The fire started on 5 August 2018 in Almonaster la Real, Spain, and satellites saw it burning for 2 days. Copernicus mapped a burnt perimeter of 300 hectares from satellite imagery, spread across a single municipality. According to EGIF (MITECO), it was detected on 5 August 2018 at 18:05 and declared extinguished on 9 August 2018.
It is the 22th largest in Huelva since 2016 (of 36 with a page). Number 6 in Spain in 2018, of 23.
The power measured by the satellite is low (15.9 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

What happened to each town
-
300 ha reached on 6 Aug0.9 %
Burnt area inside each municipality, from crossing the official perimeter with administrative boundaries. The distance runs from the point marking the centre of each area to the nearest fire: staying a kilometre away does not mean it reached the houses.
What burned
- Scrub and transitional woodland98 %
- Other land cover1.3 %
Land cover inside the perimeter according to Corine Land Cover, as reported by Copernicus.
Official record
According to EGIF (MITECO), this fire started on 5 August 2018 and burned 316 ha (the satellite measured 300 ha).

The weather day by day
ECMWF ERA5 reanalysis at the fire location, the standard reference for past weather, and the Canadian Fire Weather Index (the same system Copernicus uses), computed by WorldFires from that data. Days after the fire run until the first rain.

The smoke
CAMS · CopernicusOn 4 August 2018 the air beside the fire reached 34 µg/m³ of PM2.5. That day averaged 23: 1.5 times the WHO daily guideline (15).

Frequently asked questions
- How long did the Almonaster la Real fire last?
- Copernicus dates it between 5 August 2018 and 6 August 2018: 2 days between the first and last image with fire. According to EGIF (MITECO), it was detected on 5 August 2018 at 18:05 and declared extinguished on 9 August 2018.
- How much area did it burn?
- The perimeter Copernicus measured from satellite imagery is 300 hectares (3.0 km²). Official national figures may differ.
- Which municipalities burned?
- The fire only entered Almonaster la Real (300 ha, 0.9 %).
- Did the fire reach a town?
- The fire started in Almonaster la Real and came within 10.6 km of its centre. 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 42.5 °C, humidity dropped to 10 % and gusts hit 32 km/h. The fire danger index (FWI) reached 49, class Very 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.

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.
- Dates from the perimeter: the VIIRS detections inside it did not change them. 7 Suomi-NPP VIIRS detections on those dates.
- Compared with EGIF (MITECO): 316 official ha against 300 ha of perimeter; they agree within 25%.
- 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 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.
