Severe heatwaves across southern Europe have fueled extensive wildfires in France and Spain, forcing tens of thousands of people to evacuate their homes as firefighting efforts continue amid record-breaking temperatures.
In France, a large and rapidly spreading wildfire near the village of Saumos, about 40 kilometers west of Bordeaux along the Atlantic coast, has compelled authorities to evacuate more than 18,800 individuals, including many tourists from campsites and vacation homes. The blaze, which erupted in a dense pine forest north of the Bay of Arcachon, has consumed over 3,700 hectares since it began, with flames towering up to 10 meters high in tinder-dry conditions. Despite the destruction of several houses, no casualties have been reported.
Firefighters are deploying around 800 personnel supported by four water-bombing aircraft to contain the fire, but officials described the situation as unfavorable and unstable. Marc Vermeulen, the regional fire service chief, emphasized the unpredictable nature of the fire, which is advancing aggressively and threatening semi-urban areas. Emergency teams are working to defend homes "house by house."
Authorities have opened reception centers across nine municipalities, housing more than 2,500 evacuees. Road closures restrict access to some of the region’s most popular tourist destinations, including the Cap Ferret peninsula, known for its exclusive holiday resorts. An investigation into the fire’s cause is underway, with local officials suspecting it was sparked by a machine clearing undergrowth.
Residents and visitors described the evacuations as swift and alarming. Patrick Martineau, a resident of Le Porge, recounted police urgent warnings to leave, expressing shock at the unexpected fire risk in his community. Holidaymakers reported hurried preparations and immediate departures as the fire encroached.
The wildfires come amid an unprecedented heatwave gripping southern Europe, with temperatures reaching 44.7°C in Cieza, Spain, and several Spanish cities breaking July temperature records recently. The Mediterranean Sea is experiencing a marine heatwave affecting 80% of its surface, with sea temperatures significantly above the 1991–2020 average, according to regional monitoring agencies.
Data from the European Forest Fire Information System indicate that by July 22, nearly twice the average land area burned in the European Union for this time of year had been affected by wildfires. Both France and Spain have set new records for the number of fires and the extent of areas affected.
In neighboring Spain, authorities ordered the evacuation of 3,500 residents from a town west of Madrid due to an uncontrolled forest fire. The ongoing heat and dry conditions have contributed to a more severe and widespread fire season across the continent.
France has endured several major heatwaves since May, with rising temperatures linked to climate change leading to increased risks of drought, wildfires, and related health hazards. This year alone, more than 12,500 wildfires have been reported in the country, according to Interior Minister Laurent Nuñez. In 2022, a wildfire in the same region burned over 30,000 hectares and required the evacuation of roughly 50,000 people.
As emergency crews battle the flames, officials warn that worsening conditions could lead to even more severe fire events in the coming weeks.
