Solveira fire, March 2026 Solveira, Vilar de Perdizes e Meixide, Sarraquinhos

Out · last detection 4 Apr 2026, 13:11 UTC

The fire started on 31 March 2026 in Solveira, Portugal, and satellites saw it burning for 6 days. Copernicus mapped a burnt perimeter of 230 hectares from satellite imagery, spread across 3 municipalities.

This entry is most likely a pasture burn or a prescribed winter burn in northern Portugal, not a wildfire. In these hills scrub is burnt to renew grazing, and this fire is not in the ICNF register of rural fires. This is our assumption, based on the time of year and the lack of an official record; it is not confirmed. That is why it is left out of the wildfire rankings.

It had gone 10 days without rain (1 mm or more) when it started. Rain came after the fire: 1.5 mm on 6 Apr.

This area had burned before

42% of the perimeter overlaps earlier fires recorded since 2016: 51 ha in 2017, 12 ha in 2019, 20 ha in 2021, 26 ha in 2023. Part of it burned more than once, so the yearly figures add up to more than the 96 ha that had burned before.

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.

Frequently asked questions

How long did the Solveira fire last?
The official perimeter only gives the start date (31 March 2026). The end comes from the heat detections inside the perimeter: it burned until 5 April 2026 (6 days from 31 March 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 230 hectares (2.3 km²). Official national figures may differ.
Which municipalities burned?
The fire entered 3 municipalities: Solveira (167 ha, 14 %); Vilar de Perdizes e Meixide (61 ha, 1.6 %); Sarraquinhos (2 ha, 0.0 %).
Did the fire reach a town?
The fire started in Solveira and came within 0.8 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 20.0 °C, humidity dropped to 41 % and gusts hit 27 km/h. The fire danger index (FWI) reached 6, class Low.
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.

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.

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.

How we know this
  • 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. 16 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.
  • Probably a vegetation burn: not counted in the totals.

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 (CC0 1.0 Universal (CC0 1.0) Public Domain Dedication). 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.
