More than 366,000 people have been evacuated in France and Spain as firefighters battle unprecedented wildfires ahead of another extreme heatwave expected to push temperatures to 40C this week.

Unprecedented blazes defy containment efforts

In southwestern France, flames have scorched an area four times the size of Paris and now threaten Bordeaux, the country’s sixth-largest city. Authorities describe the fires as "extremely dangerous" and unlike any previously recorded in the region. The Gironde prefect told Le Parisien the blaze "does not follow any known pattern" and generates its own winds, complicating firefighting efforts.

Spain faces a similar crisis, with three active fire fronts burning in the mountains northwest of Madrid across the provinces of Madrid, Toledo, and Ávila. The European Forest Fire Information System reports over 300,000 hectares have burned in both countries since January, surpassing previous records.

Climate emergency fuels extreme fire conditions

Spanish Prime Minister Pedro Sánchez linked the fires directly to climate change, calling them "the most painful expression of a climate emergency" that produces more ferocious wildfires and frequent heatwaves. French President Emmanuel Macron convened an emergency cabinet meeting Monday to coordinate response efforts, while Prime Minister Sébastien Lecornu declared the country is experiencing an "unprecedented fire season."

Météo-France warns the next heatwave will settle over western France Tuesday, with temperatures peaking Wednesday. Similar conditions are forecast for Spain, where meteorological agencies predict 40C temperatures within days. Experts caution some fires may burn for weeks or months under these conditions.

Communities face ash clouds and evacuation orders

Residents near Bordeaux report constant ash clouds that darken skies and leave a burning taste in the air. Emmanuel Cerisier, a father of two, described the atmosphere as one of "tension and anxiety" as families prepare for possible evacuations. Bordeaux Airport evacuated its hotel zone Monday, though flights remain operational.

Firefighters warn some blazes have grown large enough to create their own weather systems, generating rare "fire clouds" that produce thunderstorms and strong winds. Eric Brocardi of France’s National Firefighters Federation called the phenomenon "unprecedented in France," noting it can cause spontaneous combustion of anything in its path.

What happens next

Officials urge continued vigilance as the heatwave approaches. Travelers are advised to avoid affected regions due to poor air quality, while residents should monitor local evacuation orders. The coming days will test whether firefighters can gain control before temperatures spike again.
