Wildfires Rage Across Southern Europe as Heatwave Intensifies
A severe heatwave sweeping across Southern Europe has fueled multiple large-scale wildfires in France, Spain, and Portugal, destroying tens of thousands of hectares of land and forcing the evacuation and lockdown of dozens of communities. A new fire in southern France’s Pyrenees-Orientales department has destroyed 930 hectares in a single night, while authorities in Spain have lifted the lockdown on the Costa Brava after firefighters stabilized the massive Gavarres blaze.
New Fire Erupts in Southern France
A fresh wildfire broke out on Saturday evening at approximately 19:30 local time near the commune of Trévillach in the Pyrenees-Orientales department, about 35 kilometers west of Perpignan. The fire spread rapidly through the night, consuming 930 hectares of difficult-to-access mountainous terrain. By midday Sunday, the area burned had expanded to 1,350 hectares, according to L’Humanité.
More than 580 firefighters have been mobilized to combat the flames. The fire was contained along the D2 road between Trévillach and Ille-sur-Têt but continued spreading southward, reignited by the tramontane wind on Sunday morning. Three departmental roads — D2, D17, and D66 — have been closed.
Pierre Regnault de la Mothe, the prefect of Pyrenees-Orientales, asked mayors of the surrounding communes of Rodès, Ille-sur-Têt, and Montalba-le-Château to “gather in the town hall the residents of dispersed homes.” No general evacuation order has been issued, but residents have been urged to avoid the area to facilitate emergency services.
French Interior Minister Laurent Nunez expressed being “very worried” that the fire season has started “one month early,” raising concerns about preparedness for what could be a long and severe summer. The Pyrenees-Orientales department has been under an orange heatwave alert since Saturday.
Costa Brava Lockdown Lifted
In Spain, the situation has improved significantly. The Gavarres fire, which started on Friday, July 3, near La Bisbal d’Empordà in Catalonia, burned approximately 2,300 hectares — mostly forest — and forced the lockdown of seven municipalities affecting around 50,000 people. On Sunday morning, authorities lifted the lockdown, allowing residents to return home.
According to 3Cat, the fire is stabilized but not yet controlled. Fire Chief David Borrell confirmed that 440 firefighters, 100 soldiers from Spain’s Military Emergency Unit (UME), and 16 aerial support units have been deployed. Approximately 20 buildings were affected, including eight houses completely destroyed and eight partially damaged. Eight people were injured, but no fatalities have been reported.
Catalan President Salvador Illa urged extreme caution, stating: “We continue to ask for extreme caution. No angle grinders, no work that shouldn’t be done, please.” The fire is believed to have been started by a worker using an angle grinder on the roadside — an activity prohibited under Level 3 of the Alfa Fire Risk Plan. A man was arrested on suspicion of starting the fire but was later released by a judge.
Jordi Soler, the mayor of Calonge i Sant Antoni, described the contrast between the two nights: “It was an absolutely calm night. The concern we had the night before, which was Dante-esque, has faded and given way to hope.” However, he added somberly: “These forests are completely lost, absolutely charred. The truth is it’s very sad.”
Portugal Battles Massive Blaze
In Portugal, a fire in the Vouzela municipality in the north has burned approximately 13,000 hectares since it broke out on Wednesday, July 1. Around 1,100 personnel, 366 vehicles, and five aircraft have been deployed. Two people have been seriously injured.
Portugal activated the EU Civil Protection Mechanism and bilateral agreements with Spain and Morocco for assistance. Spain sent one Canadair water bomber, and two more were requested from Morocco. Portuguese Prime Minister Luis Montenegro stated: “The whole area is at very high risk. It is better to get reinforcement from our allies to fight the fires.” Five volunteer firefighters from Belgium have also been deployed to Portugal for the summer.
Climate Context and Concerns
The wildfires are occurring during an intense and early summer heatwave, with temperatures reaching up to 44°C in Portugal. France experienced an estimated 2,000+ excess deaths during the week of June 22 due to heat. A second heatwave is now arriving in Catalonia, with almost half of Catalan municipalities under very high or extreme fire danger.
According to VRT NWS, these extreme conditions are linked to climate change rather than the El Niño phenomenon. The early start to the fire season has reignited debates about forest management, with local officials in Catalonia calling for more proactive measures, including clearing undergrowth, creating firebreaks, and better funding for rural fire prevention.
Josep Xifré, mayor of Santa Cristina d’Aro, described the Gavarres massif — “practically the lung of the Costa Brava” — as a “total and absolute powder keg” due to neglect. The 113th Tour de France, starting in Barcelona, also faces potential disruptions, with Interior Minister Nunez warning that stages could be cancelled under extreme heat conditions.
What to Watch For
Firefighters continue to battle the Trévillach fire in France, which remains active and spreading southward. The second heatwave arriving in Catalonia is expected to keep fire danger extremely high across the region in the coming days. Authorities on both sides of the border are monitoring the situation closely, with international cooperation mechanisms activated to ensure sufficient resources are available.
The fires have already destroyed over 16,000 hectares of forest and vegetation across the three countries combined, and the full ecological and economic toll — particularly for the tourism-dependent Costa Brava region — will take weeks to assess.
