Firefighters battled wildfires in Türkiye and France on Monday and more than 50,000 people were evacuated as an early summer heatwave hit Europe.

Health alerts were issued in France, Spain, Italy, Portugal and Germany. Even the Netherlands, used to a milder climate, issued a warning for high temperatures in the coming days, coupled with high humidity, Reuters reported.

"Large parts of Western Europe are experiencing extreme heat and heatwave conditions that are normally observed in July or August, rather than June," said Samantha Burgess, Strategic Lead for Climate at the EU's Copernicus Climate Change Service.

Temperatures were in some locations 5-10 degrees Celsius warmer than they otherwise should have been at this time of the year, she said.

In Türkiye, wildfires raged for a second day in the western province of Izmir, fanned by strong winds, Forestry Minister Ibrahim Yumakli said. More than 50,000 people have been evacuated from five regions, including more than 42,000 in Izmir, Türkiye's AFAD emergency management authority said.

Türkiye's coastal regions have in recent years been ravaged by wildfires as summers have become hotter and drier, which scientists say is a result of human-induced climate change.

In France, where temperatures are expected to peak on Tuesday and Wednesday, wildfires broke out on Sunday in the southwestern Aude department, where temperatures topped 40 degrees Celsius (104 degrees Fahrenheit), burning 400 hectares and forcing the evacuation of a campsite and an abbey, authorities said.

The fires were under control but not yet extinguished, authorities said on Monday. Weather service Meteo France put a record 84 of the country's 101 departments on an orange heatwave alert from Monday until midweek.
