The town of Saumos has been evacuated while around 1,000 hectares of land have been destroyed.
ADVERTISEMENTHundreds of people have been evacuated in southwestern France as new wildfires rage amid record September temperatures.
Around 1,840 people in the Gironde region have been moved from their homes since blazes broke out on Monday.
The flames have destroyed four houses, several other buildings and 3,700 hectares of land, authorities say.
The largest fire occurred near the town of Saumos, while a smaller blaze broke out south of Bordeaux, near Dax, where temperatures reached 39°C.
Local authorities reported on Thursday that the fires had been brought under control.
"The fire has not progressed. No new areas burned. No new evacuations," the local prefecture said on Twitter.
Strong winds initially hampered the overnight efforts of more than 900 firefighters from across France to extinguish the flames. Three Canadair aircraft were deployed to help, alongside firefighting helicopters and two Dash planes.
An investigation has also been launched to establish the cause of the fires.
French weather agency Meteo France announced on Monday that it had recorded record temperatures for September -- 39.1°C in the southwestern Landes region.
The area was hit by heatwaves, drought, and devastating wildfires over the summer. So far, more than 60,000 hectares of land have been ravaged in France this year.
