In Landiras, in the south of the department, 12,800 hectares were devoured by the flames.

In total, more than 37,000 people, residents or vacationers, had to leave their homes because of the fires in Gironde, which are “still not fixed”. In La Teste, an Ehpad was evacuated as a preventive measure during the night.
About 2,000 firefighters, with reinforcements from all over France, are mobilized.

A shift in the wind pushed the smoke from the two giant fires northwards and since Monday evening they have enveloped the metropolis of Bordeaux, accompanied by an acrid smell.
“There is no risk for the population”, explained the departmental fire and rescue service of Gironde, which assured to have received thousands of calls in the night.
The Department asked not to call the emergency services: “If you are afraid of breathing in the particles, put on a mask that you were using to protect yourself from Covid. You have to wait for the wind to drop”.
Smoke and smells were perceived as far as Charente and Deux-Sèvres, according to the authorities.
In La Teste, the fire notably carried away the five campsites evacuated of their 6,000 occupants on July 13, including that of Dune-Les Flots Bleus, immortalized by the films “Camping”.
