More than 10,000 residents have been evacuated from 26 communes near Trévillach and Perpignan in southwestern France since a wildfire broke out Saturday night, burning approximately 4,600 hectares across the Pyrénées-Orientales department [1]. Seven hundred firefighters are working the French blaze. It remains uncontrolled.

When this paper reported Monday on the EU's record civil-protection air fleet assembled for 2026, the story was capacity: the fleet existed, it was the largest ever assembled, and it was ready for the summer fire season. The fleet is now deployed. The Perpignan fire is today's test of whether that capacity is sufficient against the conditions driving southern Europe's 2026 fire environment.

The European Commission has sent four Bombardier water-bombing aircraft from contributing nations including Cyprus and Sweden [1]. Across four countries — France, Spain, Portugal, and Greece — active fires have scorched more than 19,000 hectares since Friday, an area exceeding 190 square kilometers [2]. That figure is still growing.

Country by country

In France, the Perpignan blaze is the country's largest wildfire of the summer. The fire broke out in terrain described as remote and hard to access — the kind of topography that limits the effectiveness of ground crews and makes aerial assets more critical and less precise. Rail service between Perpignan and Villefranche-Vernet-les-Bains was suspended Tuesday. The Tour de France Stage 3 route passed through the affected region; spectators were barred from the French section of the course [3].

In Spain, authorities in the Girona region ordered nearly 50,000 people to shelter in place or evacuate as multiple fires moved across the Catalan interior [1]. The Girona fires are geographically adjacent to the Perpignan blaze — the Franco-Spanish border is ecological, not a firebreak.

In Portugal, a major blaze in the north has reached 80 percent containment on approximately 13,000 hectares burned — the relative success story in this event cluster [1]. Portuguese authorities deployed significant national and European aerial assets early in the event, and favorable wind shifts helped consolidate containment lines.

In Greece, the Thessaloniki area has received a toxic-smoke advisory as fires in the region push particulate matter toward the city's 1.1 million residents [2]. The Thessaloniki advisory is a distinct category from the Perpignan and Girona evacuations: it is an urban-fringe air-quality event driven by fire perimeters that are not directly threatening residential structures.

The tourist-season dimension

The fires have arrived during peak summer occupancy across Catalonia, Languedoc, and the Côte Vermeille — the coastal zone directly south of Perpignan. Irish travelers who had booked summer holidays in the region were photographed leaving belongings behind in evacuated gîtes [3]. Spanish border-zone accommodation in Girona province faces parallel disruption. The economic and logistical cost of disrupting peak summer tourism in a region heavily dependent on it is substantial and not yet quantified [3].

What the fleet test shows so far

The EU's record air fleet represents a genuine increase in collective capacity over prior summers. The Perpignan blaze is the first major event at which that capacity has been actively committed since the season began. The preliminary finding is that four aircraft against a fire in remote terrain, under summer heat conditions, with favorable topography for fire spread, has not yet produced containment.

That is not a verdict on the fleet. Aircraft are most effective at slowing fire advance and protecting specific assets; they do not extinguish large fires in rough terrain. Ground crews must close the lines. Seven hundred firefighters working a hard-to-access blaze in southern France is a significant deployment. It has not, as of Tuesday morning, been sufficient to stop the fire's spread [1].

Portugal's 80 percent containment figure provides a reference point: early aerial commitment plus favorable wind conditions can contain a 13,000-hectare fire in four to five days [1]. France's Perpignan blaze began Saturday night. Tuesday is day three. Containment has not been announced [1].

The fires are burning in areas where a "virtually impossible without climate change" heatwave passed in June, leaving vegetation desiccated by the time July brought the fire season's peak wind and temperature conditions [2]. The record fleet is a response to a fire environment that the previous decade's fleet was not built for.
