The mayor of Bordeaux is preparing for all eventualities as a massive wildfire burning in the Gironde region has advanced to within 15 kilometers (nine miles) of the southwestern French city. Thomas Cazenave stated his administration is ready to accommodate a large number of people should further evacuations be ordered.

This blaze is part of an unprecedented fire season in France, described by President Emmanuel Macron as the toughest since World War Two. The scale of the crisis has led to over 220,000 people being evacuated across France and more than 100,000 in Spain, where fires also rage uncontrolled west of Madrid. An intense heatwave forecast for Tuesday could further complicate firefighting efforts.

While firefighters had reported making progress on Monday, improving the situation compared to the previous day, President Macron cautioned against complacency. He noted that rising temperatures and persistent winds mean "we must remain humble." Interior Minister Laurent Nuñez had earlier warned that the fire "has a life of its own."

The mayor of Cestas, a town south of Bordeaux, described the situation as "catastrophic" and "the fire of the century." He recounted the evacuation of 17,000 residents from his town during the night when the fire rapidly advanced. So far, the region has seen 42,000 hectares (103,000 acres) of land burned and 240 houses destroyed.

Despite some containment efforts and the creation of firebreaks, the risk remains significant due to flying embers and the potential for sudden wind changes. "We put all our energy into creating protective firebreaks, but we are all scared in front of this situation," the Cestas mayor admitted.

French Prime Minister Sébastien Lecornu highlighted the severity of the season, reporting that since January, 116,085 hectares (286,852 acres) have burned and 13,566 fire starts have been recorded. He also revealed that nine out of 10 fires are human-caused, often due to carelessness such as discarded cigarette butts or barbecues, though some fires are deliberately set, leading to 162 arrests since July 6.

Wildfires continue to affect multiple other French regions, including Var, Landes, and Haute-Corse on the island of Corsica. Meanwhile, neighboring Spain is in its fifth day of a national emergency due to raging wildfires west of Madrid, which satellite imagery shows have spread significantly over recent days.

Authorities are grappling with the immense challenge of controlling these widespread fires, exacerbated by extreme weather conditions. The ongoing crisis underscores the growing threat of wildfires in Europe, driven by climate change and human activity.
