Le Porge – 23 July 2026: A large-scale forest fire north of the Bassin d’Arcachon once again highlighted the particular vulnerability of the Gironde on Thursday. According to the AFP news agency, around 2,400 hectares near Le Porge were affected, and more than 20,000 residents and holidaymakers had to leave the area. The fire had not yet been fully brought under control by the evening.
The situation is affecting an area with exceptionally large, contiguous forest tracts. According to the prefecture, forests cover around 520,000 hectares in the Gironde, about half of the department’s area. Many sections belong to the Landes de Gascogne forest massif. Pine forests, sandy soils and, in some cases, difficult-to-access dune areas create conditions in which fires can spread rapidly.
The key factor at present is the drying out of vegetation. On 23 July, Météo-France reported a high to very high wildfire risk across large parts of southwestern and western France. Intense heat, very dry soils and dry northerly to northeasterly winds simultaneously increase the likelihood of ignition and accelerate the spread of fires. Bordeaux recorded 34 degrees on Thursday, with temperatures of up to 34 degrees expected again on Friday.
However, weather conditions do not explain every fire outbreak. According to Météo-France, nine out of ten vegetation and forest fires in France are caused by human activity. These include carelessness, technical defects, flying sparks and open fires. Areas near roads, settlements and heavily visited tourist locations are particularly at risk. According to the weather service, around 80 percent of fires start less than 50 metres from residential development.
The disaster of summer 2022 continues to shape the region. At that time, more than 30,000 hectares of forest burned in the Gironde, particularly near Landiras and La Teste-de-Buch. The damage led to new protective measures, emergency-service drills and an evacuation plan for the Lège-Cap-Ferret peninsula. There, the only road connection, the D106, can become impassable during a major fire; an evacuation by sea is therefore also planned.
The region’s vulnerability is thus the result of several factors: extensive and partly uniform pine stands, summer drought, wind, high visitor numbers and growing pressure from climate change. It does not directly cause fires, but it worsens the conditions for their outbreak and containment. Authorities are therefore relying on the preventive clearing of combustible material, access corridors and restrictions during periods of particularly high risk.
The situation will remain tense in the coming days. Météo-France expects possible relief only with rainfall over the weekend. Until then, it will be important to prevent possible ignition
