Ourém fire, 15 August 2022 União das Freguesias de Rio de Couros e Casal dos Bernardos, Sabacheira, Seiça

Out · last measured on 15 Aug 2022

The fire started on 15 August 2022 in União das Freguesias de Rio de Couros e Casal dos Bernardos, Portugal, and satellites saw it burning for 1 day. Copernicus mapped a burnt perimeter of 164 hectares from satellite imagery, spread across 3 municipalities. According to ICNF, it was detected on 15 August 2022 at 15:32 and declared extinguished on 16 August 2022.

Number 80 in Portugal in 2022, of 107.

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.

Frequently asked questions

How long did the Ourém fire last?

How much area did it burn?
The perimeter Copernicus measured from satellite imagery is 164 hectares (1.6 km²). Official national figures may differ.
Which municipalities burned?
The fire entered 3 municipalities: União das Freguesias de Rio de Couros e Casal dos Bernardos (129 ha, 2.9 %); Sabacheira (35 ha, 1.0 %); Seiça (0 ha, 0.0 %).
Did the fire reach a town?
The closest fire to a town centre came within 1.3 km of União das Freguesias de Rio de Couros e Casal dos Bernardos. 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 27.1 °C, humidity dropped to 42 % and gusts hit 41 km/h. The fire danger index (FWI) reached 32, class 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.

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 (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.
