Deadly Heatwave Grips Europe As Temperatures Shatter Records

by Stefan J. Bos, Worthy News Europe Bureau Chief

PARIS/AMSTERDAM/BUDAPEST (Worthy News) – A deadly heatwave tightened its grip on Europe Wednesday, sending temperatures soaring to record levels, straining power grids, disrupting transport, and raising fears of additional casualties across the continent.

French authorities said at least 40 people have drowned since last week, many while attempting to cool off in unsupervised swimming areas. Prime Minister Sébastien Lecornu warned the deaths highlighted the dangers posed by the extreme weather.

Temperatures exceeded 40 degrees Celsius (104 degrees Fahrenheit) in parts of France, while the western city of Nantes recorded 41 degrees Celsius (105.8 degrees Fahrenheit). Spain also broke its June temperature record, with forecasters warning of highs near 40 degrees Celsius (104 degrees Fahrenheit) in several regions.

Britain provisionally recorded its hottest June day on record, with temperatures reaching 35.7 degrees Celsius (96.3 degrees Fahrenheit), while Scotland experienced its hottest day of the year at 29.4 degrees Celsius (84.9 degrees Fahrenheit).

In Germany, forecasters warned temperatures could climb to 41 degrees Celsius (105.8 degrees Fahrenheit) later this week, potentially breaking the country’s June heat record.

RECORD TEMPERATURES ACROSS EUROPE

The heatwave stretched from the Iberian Peninsula to Eastern Europe, prompting high-level warnings in more than a dozen countries, including France, Germany, Hungary, Italy, Spain, and the United Kingdom.

Extreme heat also reduced French nuclear power production, as warmer rivers limited the availability of cooling water for reactors.

The tropical temperatures exposed a problem shared by much of Europe: many homes, schools, hospitals, and public transport systems were built for a cooler climate and lack air conditioning.

Among those struggling was Anna, a freelance translator who said the heat had become so intense that she was forced to spend hundreds of euros on taxis and alternative workspaces to escape stifling indoor temperatures.

“We’ve had temperatures over 40 degrees Celsius for three days in a row, which never happened before,” she said. “Your brain is not working properly in that heat, and I need my brain. That’s what I work with.”

LACK OF AIR CONDITIONING ADDS TO CHALLENGES

Anna also expressed concern about the lack of air conditioning in some healthcare facilities where vulnerable patients are receiving treatment.

In the Netherlands, authorities activated a national heat plan as temperatures were forecast to reach 37 to 38 degrees Celsius (98.6 to 100.4 degrees Fahrenheit) in some areas.

The heatwave follows a weekend of violent storms that killed at least one person and unleashed nearly 190,000 lightning strikes across the country, one of the most intense thunderstorm outbreaks in recent Dutch history.

Health officials urged residents to protect vulnerable people and advised households to block sunlight from entering homes, including by hanging curtains or sheets outside windows.

Researchers warned that rising temperatures pose growing health risks in a country where many buildings were designed to retain warmth during colder months.

DUTCH AUTHORITIES ISSUE HEAT WARNING

The prolonged heatwave also raised concerns about large outdoor gatherings planned across Europe, including the planned Budapest Pride march in Hungary’s capital, where tens of thousands of people are expected to attend despite forecasts showing temperatures could reach at least 36 degrees Celsius (96.8 degrees Fahrenheit).

Under former Prime Minister Viktor Orbán, authorities banned last year’s Pride event, though hundreds of thousands of people still turned out in defiance of the restrictions, drawing international attention.

Environmental campaigners said the heatwave underscored the need for governments to prepare for more frequent periods of extreme weather.

“The summer of ’76 may be seared into the nation’s memory, but it’s quickly being overtaken by even more terrifying heatwaves,” said Greenpeace UK political campaigner Angharad Hopkinson. “The only way off this treadmill is to reduce our dependence on fossil fuels.”

Numerous climate scientists link the increasing frequency and intensity of heatwaves to human-driven climate change. However, other experts and researchers argue that climate fluctuations and extreme weather events have also occurred naturally throughout history.

HEALTH EXPERTS URGE CAUTION

Researchers estimate that tens of thousands of people die from heat-related causes across Europe each year, highlighting the dangers posed by prolonged periods of extreme heat.

Forecasters expect temperatures in parts of Western Europe to ease gradually from Friday, though several countries in Central and Eastern Europe are expected to face another scorching weekend, with temperatures approaching the upper 30s Celsius in some areas.

Health experts urged people to drink plenty of water, avoid prolonged exposure to the sun during the hottest hours of the day, seek shade whenever possible, and regularly check on elderly and vulnerable relatives and neighbors.

Even Pope Leo XIV appeared to lead by example, drinking a glass of water after his weekly general audience as much of Europe sweltered under record-breaking temperatures.
