A severe heatwave has struck parts of Europe, pushing temperatures up to 43°C in southern France and heightening wildfire risks in key wine regions.
Bulgaria faced wildfires along its southern borders, while Hungary recorded its highest-ever weekend temperatures. Europe is now the fastest-warming continent globally, with land temperatures rising approximately 2.3°C above pre-industrial levels—nearly double the global average. This acceleration intensifies heatwaves, with 2025 projected to be among the warmest years on record.
The EU’s Copernicus climate service reports that this summer’s burned areas are well above average, with significant fires in Spain, Portugal, and fatal blazes in Greece since June.
In the UK, the Met Office predicts the fourth heatwave of the season will peak near 33°C in London by Tuesday. The UK Health Security Agency issued a yellow alert advising caution for older adults and people with health conditions.
France’s Aude department remains vigilant as firefighters contain a massive wildfire that consumed 16,000 hectares last week in its wine-growing and Mediterranean scrubland areas. While under control, hotspots still pose a reignition threat, and full extinguishment could take weeks.
Météo-France issued red heat alerts—the country’s highest warning—in 12 departments, covering areas from the Atlantic coast to the Mediterranean plains, with 41 other departments under orange alerts. The nearby microstate Andorra is also affected.
Agricultural climatologist Serge Zaka described the situation as “a nightmare,” warning that this extreme heat is far from normal summer weather. Residents adapted by closing shutters and seeking shade indoors as public outdoor spaces emptied under the intense sun.
Since its introduction in 2004 following a deadly heatwave, France’s red alert is rare and reserved for prolonged extreme heat posing significant health risks and societal disruption. The alert grants local authorities powers to cancel outdoor activities, close venues, and modify school and camp schedules to protect public health.
