Over 1,100 firefighters battle northern Portugal wildfire as heatwave fuels 10,000-hectare blaze

Fire progression and response

The wildfire began in the municipality of Vouzela, in the district of Viseu, during the night of Wednesday to Thursday, July 2. By Friday evening, the national commander of civil protection, Mario Silvestre, reported that the blaze had consumed an estimated 10,000 hectares of forest and scrubland. The fire front advanced into neighboring communes in the Aveiro region, making containment difficult. On Saturday, more than 1,100 firefighters were still deployed, backed by around 380 vehicles and eight water-dropping aircraft and helicopters. A Spanish military unit arrived to assist after Portugal activated the European Union's civil protection mechanism on Friday. Despite the scale of the operation, the fire remained uncontained as of Saturday afternoon.

Casualties and evacuations

The civil protection authority confirmed at least nine injuries. Two civilians were listed in serious condition: one with burns and another injured in a fall. No deaths have been reported. While the Vouzela fire was the only large active blaze on Saturday, smaller fires were burning in Setúbal (south), Arouca (north) and Barcelos (north). Across the border in Spain, a separate fire near the Costa Brava forced authorities to confine around ten municipalities in Catalonia, a popular summer tourist area.

International assistance

Facing extreme fire weather, the Portuguese government activated the EU civil protection mechanism and its bilateral agreements with Spain and Morocco. Lisbon requested two Canadair water-bomber aircraft from Spain and two from Morocco. By Saturday, one Spanish Canadair had already been deployed, and a Spanish military unit was on the ground. The interior ministry confirmed the requests, emphasizing that the European mechanism enables rapid cross-border support during large-scale emergencies. The activation came as temperatures soared and firefighting resources were stretched.

Weather and climate context

The fires are being fueled by an intense heatwave. Portugal's meteorological agency placed 13 of the 18 mainland districts under red alert on Saturday, with temperatures forecast to reach 44°C locally. The maximum alert level will remain in effect for seven central and southern districts on Sunday. The Iberian Peninsula is highly exposed to the effects of climate change, which is making heatwaves more frequent and droughts more prolonged. Portugal recorded its hottest summer since 1931 last year, and the country remains marked by the memory of the 2017 fires that killed more than 100 people. The Vouzela fire is the first large wildfire of the summer season, which authorities fear could be severe given the prolonged dry spell and early heatwave.
