Laborers were pausing outdoor work and tourists looked for some shade on Tuesday as Greece sweltered under its third heat wave this summer, with soaring temperatures gripping the wider Balkan region and fueling wildfires in Albania.
Situated at Europe's southernmost tip, Greece, which attracts dozens of millions of tourists every year, has always had hot and dry summers.
But in recent years, climate change has led to longer and more severe heat waves, as well as destructive floods and wildfires.
Couriers, food delivery riders and builders in the wider area of the Greek capital, Athens, and other regions were among those ordered to pause work from midday until 5 p.m., as the mercury was expected to climb as high as 43 degrees Celsius (109.4 degrees Fahrenheit), the labor ministry said.
Workers with underlying health issues were advised to work remotely to avoid heat stress.
Outside the parliament building in central Athens, a soldier used a towel to wipe the sweat from the face of a presidential guard.
Tourists in Athens, one of the most densely populated capitals in Europe, sitting on a plain flanked by mountains, sought out air-conditioned restaurants and stores, and some said they were staying inside in the middle of the day.
Authorities announced that the Acropolis, which sits on a rocky hill offering barely any shade and is Greece's most visited ancient site, would be closed for five hours from midday on Tuesday and Wednesday, a common step when temperatures soar.
The heatwave will continue until Sunday, the Greek meteorological service said.
Scorching heat also gripped neighboring Bulgaria on Tuesday, with authorities urging businesses to give away water and cut physical labour during high-risk hours.
In Montenegro, major roads were congested as many rushed to the beaches to find relief from the heat. In Albania, firefighters assisted by four aircraft from Italy and Greece battled two wildfires at a national park in the north and near the southwestern village of Dukat.
Last month, large parts of Western Europe sweltered in another severe heat wave that left many dead and triggered forest fires and health alerts across the region.
Across the globe, 2024 was the warmest year on record, with temperatures exceeding 1.5 Celsius above the pre-industrial era for the first time.
Research published last week showed that the soil surface temperature around Athens rose in some places by as much as 10 degrees Celsius since July 2024 after fires destroyed vegetation.
