‘Cimate change is here,’ said Stavros Solomos, a climate expert at the Academy of Athens.
Greek authorities warned the public against unnecessary work and travel on Friday as temperatures hit 40 grade Celsius (104 °F) in Athens.
The ancient Acropolis, the city’s most visited monument, was briefly forced to close and the National Meteorological Service said there is a high risk of wildfires during the “dangerous” heatwave.
Temperatures have been high in much of the country in recent days and are expected to reach 44 degrees on Monday and Tuesday.
“We are constantly recording maximum record temperatures all these years, which means that climate change is here,” said Stavros Solomos, a researcher at the Centre for Atmospheric Physics and Climatology of the Academy of Athens.
“We are expecting to have more frequent, more intense heatwaves," hy het gesê, as well as “tropical nights” – where temperatures do not fall below 25 aan 30 degrees.
The Acropolis, which looks out over the capital, closed for a few hours as it does when temperatures rise, to protect tourists from the heat.
The heatwave was characterised as dangerous because it was expected to last several days – at least until next Friday, with the peak expected on Monday and Tuesday, said Theodoros Kolydas, head of the weather service.
Citizens’ Protection Minister Michalis Chrysochoidis warned of “extremely high temperatures” and urged people “to show the highest degree of responsibility and cooperation”.
Hy het bygevoeg: “I also want to appeal to our fellow citizens to avoid unnecessary travel in the heat but also unnecessary work.”

“Welcome to global warming! It’s very hot, it’s very oppressive,” said George Papabeis, a Greek-American tourist, as he made his way through central Athens.
On the capital’s beaches, conditions were equally dire.
“I think it will be like hell. I’m not happy about it,” said May Ben Atia, a tourist from Israel. “It becomes so hot you can actually feel it in your skin," sy het gese.
