Athens Struggles to Stay Cool as Tourism and Heatwaves Collide

Athens Caught Between Soaring Temperatures and Surging Tourism

Climate Crisis Closes Iconic Landmarks

The Acropolis of Athens, one of the world’s most historic sites, has faced repeated midday closures in recent summers as temperatures soar past 40°C (104°F). In 2024 alone, the city recorded record heat, forcing emergency measures to protect both tourists and staff.

Greece’s national weather service warns that July and August could bring even more dangerous conditions, just as Athens expects a record 10 million tourists. The combination of extreme heat and mass tourism is pushing the city’s infrastructure and ecosystem to the brink.

“Standing under the sun at the Parthenon can feel like an endurance test,” says local tour guide Iris Plaitakis.

Urban Heat Island and Infrastructure Collapse

Athens is Europe’s hottest mainland capital, with concrete-heavy neighborhoods and limited green cover. Its dense urban sprawl amplifies the urban heat island effect, worsening conditions for residents and tourists alike.

“Heatwaves cause over 80% of weather-related deaths in Europe,” notes Ine Vandecasteele from the European Environment Agency. Elderly citizens, a large part of Athens’ population, are especially vulnerable.

The City’s Response: Cooling Centers, Forests, and Water Innovation

Mayor Haris Doukas has placed climate resilience at the top of the city’s priorities. Athens is implementing solutions like:

• Air-conditioned cooling centers in tourist zones and neighborhoods

• 7,000+ trees planted, with a goal of 28,000 in 4 years

• Greece’s first microforest in Kypseli, Europe’s most densely populated district

• Reviving a Roman aqueduct in Chalandri to irrigate green areas and cool public zones

These efforts aim to reduce perceived temperatures by 5°C over the next five years.

Tourist Economy vs Sustainability

Tourism is a double-edged sword. It brought Greece back from economic ruin during the 2010s, yet today contributes to water shortages, real estate inflation, and infrastructure stress.

Athens’ coastal stretch, dubbed the Athens Riviera, is seeing massive luxury development including the Ellinikon project—Europe’s largest urban park under construction. But critics argue such projects displace locals and consume essential resources.

A Call to Adapt: Shifting Tourism and Climate Practices

With water reservoirs shrinking and wildfires increasing, authorities are encouraging off-peak tourism in spring and fall. New initiatives aim to educate visitors at arrival points on staying cool and minimizing energy use.

Athens is not alone—global destinations from Barcelona to Bangkok are also battling overtourism under worsening climate conditions.
