Out · last detection 7 Aug 2026, 14:12 UTC
The fire started on 7 August 2026 in Carrapichana, Portugal, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 311 hectares from satellite imagery, spread across 3 freguesias. According to ICNF, it was detected on 7 August 2026 at 13:40 and declared extinguished on 8 August 2026.

32.6°C · 29% RH
High of 32.6 °C and minimum humidity of 29% on 7 August 2026; gusts of 35 km/h on 7 August 2026.
These are model values for a cell of about 25 km, not from a weather station: they may differ from what was measured on the ground.

It had gone 31 days without rain (1 mm or more) when it started. Rain came after the fire: 1.0 mm on 8 Aug.
This area had burned before
63% of the perimeter overlaps earlier fires recorded since 2016: 168 ha in 2017, 24 ha in 2019, 24 ha in 2024. Part of it burned more than once, so the yearly figures add up to more than the 196 ha that had burned before.
Burnt area inside each freguesia, 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.

Residents< 20
Inside the perimeter there were about 0.18 hectares of built-up land and almost nobody lived there (GHSL 2025, satellite-based estimate).
This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned. The GHSL 2025 epoch is a projection made from 2020 and earlier data.
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.

First rain (1 mm or more) after it ended: none in the following ten days.
It burned an area similar to its twins (311 ha against a median of 383 ha) and lasted 1 day, against 2 days.
In 23 of 61, 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 2.3 mm.

It was considered over on 7 Aug, and on 8 Aug 1.0 mm fell. We do not know whether the rain or the firefighters put it out. Twins with rain when they ended: 38 of 61, with a median of 2.3 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.

Sentinel-2 did not pass over on that day. Try another date, or use false colour, which is daily.
If the day is cloudy, change the date: each satellite passes once a day. In false colour the burnt ground looks brown or red.

The official perimeter only gives the start date (7 August 2026). The end comes from the heat detections inside the perimeter: it burned until 7 August 2026 (1 day from 7 August 2026), the last day with detections before more than 10 days in a row without any, so it is approximate. According to ICNF, it was detected on 7 August 2026 at 13:40 and declared extinguished on 8 August 2026.
How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 311 hectares (3.1 km²). Official national figures may differ.
Which freguesias burned?
The fire entered 3 freguesias: Mesquitela (131 ha, 7.8 %); Carrapichana (120 ha, 21 %); Juncais, Vila Ruiva e Vila Soeiro do Chão (60 ha, 3.0 %).
Did the fire reach a town?
The fire started in Carrapichana 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 32.6 °C, humidity dropped to 29 % and gusts hit 35 km/h. The fire danger index (FWI) reached 39, class Very high.
Where does this data come from?
From the EFFIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of Portugal (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: 61. Their median duration was 2 days and their median area 383 ha; 25 % went past 1,000 ha. In 23 of 61, 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 2.3 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.
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. 8 Suomi-NPP VIIRS detections on those dates.
Compared with ICNF: 300 official ha against 311 ha of perimeter; they agree within 25%.
Weather: Copernicus ERA5 reanalysis at the fire location, in cells of about 25 km.
Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2025, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.
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. Freguesia boundaries come from geoBoundaries ADM3 (CC0 1.0 Universal (CC0 1.0) Public Domain Dedication). The area per freguesia is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ slightly from each country’s official figure.
