French authorities issued urgent evacuation orders for nearly 4,000 people on Tuesday as a new heat wave threatened to destabilize the containment efforts of a massive wildfire near Bordeaux. The situation remains precarious across southwestern Europe, where fires in France and Spain have already displaced approximately 330,000 residents and tourists. Spain is currently navigating its fourth heat wave of the summer, with several blazes burning out of control, including the largest wildfire in the country's recorded history.
While firefighters in the French region of Gironde managed to hold the perimeter of the blaze steady overnight at 420 square kilometers (162 square miles), officials cautioned that the fire remains stabilized rather than fully contained. The risk of rapid expansion persists as temperatures climb and humidity levels drop. The latest precautionary evacuation order covers campsites, holiday villages, tourist residences, and leisure parks surrounding the resort of Lacanau, including Lacanau Ocean and both shores of Lacanau lake, according to Gironde regional authorities. Eric Brocardi, spokesperson for France's national firefighters federation, described the situation as fragile, telling BFMTV on Tuesday that crews will continue to aggressively combat the flames despite the challenging weather forecast.
The unpredictable nature of this blaze, which has raged since last week, has seen it transform into a self-feeding firestorm. Despite the fire having burned an area four times the size of Paris and forcing 220,000 people from their homes and vacation spots, 93 firefighters have sustained injuries during the operation. Military engineers and fire crews resumed work early Tuesday to construct tactical firebreaks, with 103 kilometers (64 miles) already completed to prevent further spread. Consequently, the A63 highway remains partially closed, and rail traffic south of Bordeaux is suspended, with the exception of routes leading to Toulouse.
In contrast, progress was reported in the neighboring Landes region, where a separate, fixed wildfire allowed authorities to lift evacuation orders for more than 30,000 people. French President Emmanuel Macron confirmed the positive development on Monday evening, noting that the fire's advance had been stopped. Approximately 15,000 individuals in areas like Sanguinet, Parentis-en-Born, and parts of Biscarrosse were authorized to return home, including residents of Biscarrosse's aviation village and a large campground. However, officials warned that the fire is not extinguished and that surveillance and damping-down operations will continue for days or possibly weeks to monitor for potential flare-ups caused by wind, drought, or residual hot spots.
The struggle against the elements is intensifying as France’s national weather service issued a yellow heat warning for the Gironde department, with temperatures expected to reach between 33 and 35 C (91 to 95 F). Interior Ministry data indicates that over 116,000 hectares have burned in France this year, following a record-breaking June across Western Europe. In Spain, Interior Minister Fernando Grande-Marlaska expressed cautious optimism after overnight efforts, though he warned that the arrival of a fourth heat wave, with temperatures predicted to exceed 40 C (104 F), could lead to a rapid deterioration of conditions. Spain has already evacuated roughly 79,000 people and ordered another 30,000 to shelter in place under a national emergency declaration.
The greatest concern in Spain remains two large fires that have at times come close to merging into a single mega-blaze in wooded hills about an hour's drive west of Madrid. Another fire in the eastern province of Castellón has also forced mass evacuations. A fire burning through hilly, rural terrain in Ávila, west of Madrid, has officially become Spain's largest on record, scorching more than 500 square kilometers (193 square miles)—an area five times larger than Barcelona. David Gonzalez, a 48-year-old gardener who used his van to deliver supplies to firefighters in Ávila, described the scene as inhuman, noting the anger and helplessness felt by locals as they look at the burned valley and houses. Ecology Minister Sara Aagesen reported that 1,530 square kilometers (590 square miles) have burned in Spain so far this year, which is six times the total area recorded during the first half of 2025. Prime Minister Pedro Sánchez has called for a national pact to address the escalating threat of wildfires, which are being exacerbated by the effects of climate change.
Ninety-three firefighters have been injured while battling the blaze, the prefecture said.
Hundreds of firefighters backed by military emergency brigades and water-dropping aircraft continued battling several major wildfires in Spain, including the largest ever recorded in the fire-prone country.
