Wildfires in south-west France flare up as region braces for new 40C heatwave
Firefighters in France's Gironde region are battling flare-ups from wildfires that have already forced more than 70,000 evacuations, with a fourth heatwave bringing 40C temperatures by Wednesday.

France's Gironde region faces renewed wildfire flare-ups as a fourth summer heatwave pushes temperatures to 40C. Over 2,000 firefighters are deployed, four colleagues have died, and the region braces for worsening conditions while Spain and Portugal also battle major blazes.
Big fires are burning in the forests near Bordeaux, France, and the firefighters are working day and night to stop them. A new super-hot heatwave is coming, which will make the fires even harder to fight, like trying to blow out a birthday candle inside a hot oven.
Analysis
Gironde's Second Front
The Gironde region has emerged as the epicentre of France's worst wildfire season in recent memory, with regional prefect Sophie Brocas warning on Tuesday that 14 already-burned areas saw fresh flare-ups. Eric Brocardi of the national firefighters' federation described the battle as "David against Goliath" — a striking image given that 2,000 personnel are now committed to the front. Yet despite this mobilisation, four firefighters have died across France in recent weeks, underscoring the human toll of an intensifying fire season. The Gironde fire came within 15 kilometres of Bordeaux on Monday, and Commander Rémi Lassoureille's fears about the metropolitan area are far from abstract: air quality has deteriorated sharply, with residents and tourists donning masks and restaurants closing due to airborne ash.
A Heatwave Stacking on a Heatwave
What makes the current situation particularly alarming is the convergence of active fires with an incoming fourth heatwave forecast to push temperatures to 40C by Wednesday — conditions that typically accelerate fire spread and complicate containment. Spain faces similar extremes, though Prime Minister Pedro Sánchez struck a cautiously hopeful tone, suggesting that "light is beginning to appear at the end of the tunnel" as around 44,000 evacuees were allowed to return home. Portugal has deployed 400 firefighters to a large blaze in the eastern Guarda area, demonstrating that the Iberian Peninsula is bearing parallel strain. The simultaneous pressure on multiple national fire services raises questions about whether European mutual-aid mechanisms can keep pace when heat domes and tinder-dry forests align.
Beyond the Blaze: Economic and Social Ripples
The fires are reshaping local economies beyond the immediate loss of property. An estimated 240 homes and houses have been destroyed, and Peggy Plouhinec of Château Picque Caillou told the BBC that tourists had "deserted" the Bordeaux wine region, warning the hospitality sector will suffer this summer despite improving air quality. The interior ministry reports 184 arrests since 6 July in connection with the fires — including a 23-year-old man in the Var region now facing 15 years' imprisonment — a sign that authorities are treating arson as a significant driver of the crisis. With 220,000 already evacuated around France and 4,000 more tourists ordered to leave Lacanau's coastal campsites, the logistical burden on emergency planners and the tourism industry alike is reaching unprecedented levels, raising longer-term questions about regional resilience in a warming Mediterranean climate.
Key points
- 2,000 firefighters are deployed in France's Gironde region, with four colleagues having died across the country in recent weeks
- Fourteen previously burned areas saw new flare-ups on Tuesday as a fourth heatwave bringing 40C temperatures approaches by Wednesday
- More than 70,000 people have been evacuated over the past week, with an additional 4,000 tourists ordered to leave Lacanau campsites on Tuesday
- Spain has lifted some evacuation orders allowing 44,000 people to return home, while Portugal battles a separate major fire in the Guarda region with 400 firefighters
- French authorities have arrested 184 people since 6 July in connection with the fires, including a 23-year-old man in the Var region now facing 15 years' imprisonment
Sunday night's rainfall offered temporary relief to the Gironde vineyards, and Bordeaux's city centre remains outside the immediate fire perimeter. Spanish authorities have begun lifting evacuation orders for 44,000 residents, and the mobilisation of 2,000 firefighters suggests national capacity is being marshalled effectively to contain the current blaze front before Wednesday's peak heat.
With a fourth heatwave forecast to bring 40C temperatures and 14 areas already experiencing renewed flare-ups, containment could quickly collapse, especially if winds shift toward Bordeaux's metropolitan area. The loss of four firefighters, 184 arson-related arrests since early July, and the destruction of 240 homes point to a summer crisis that may overwhelm regional response capacity if conditions worsen as forecast.
