Europe is enduring a historic, intense heatwave causing infrastructure failures due to unpreparedness for extreme heat. In France, electrical transformers have malfunctioned from the heat, leaving over 106,000 buildings and homes without power amid temperatures exceeding 41 degrees Celsius. Meanwhile, fan and air conditioner sales have surged to a record high of 1,000 times normal levels.
The severe heatwave continues to blanket Europe, with France's average daytime and nighttime temperature reaching 29.8 degrees Celsius this week—the highest recorded since records began in 1947. French authorities have upgraded the weather alert to the highest level, red, adding four more provinces. Currently, around 44 million people—over 90% of the population—face a critical heat emergency, with temperatures ranging from 39 to 41 degrees Celsius across regions from Brittany to Paris.
The prolonged intense heat has severely damaged infrastructure. French officials recently reported a major power outage in the northwestern Finistère province after an electrical transformer failed due to excessive temperatures. This left up to 106,000 residents without power. Rescue teams and engineers worked overnight to provide backup power and install emergency generators for medical centers and nursing homes as a priority.
This climate crisis has drastically altered consumer behavior in France. Since most European homes are built to retain warmth during winter and lack cooling systems, demand for cooling appliances has surged unprecedentedly.
Alexandre Bonpart, CEO of the major supermarket chain Carrefour, revealed that on Monday alone, the company sold up to 30,000 fans and portable air conditioners within hours—1,000 times the usual daily sales. Amazon's platform also reported nearly double sales compared to last year. Local electricians said they are overwhelmed with emergency air conditioner installation requests, with many residents foregoing formal permissions from building management due to intolerable heat.
"Visiting Paris in this weather is terrible. We feel like we’re about to suffocate—on the streets, in the subway stations, and even inside our rented rooms," said John Biller, a 45-year-old American engineer traveling in the city. He added that he had to move to a hotel with air conditioning.
A tragic incident occurred in southeastern France where two young children, aged 2 and 4, died after succumbing to heat while trapped inside a car parked outside their home. The mother reported that the children had secretly climbed into the vehicle without her knowledge.
Meteorologists attribute this heatwave to a weather phenomenon called the 'Omega block,' characterized by air masses that trap and intensify heat day by day. Global warming acts as an accelerator, with experts noting that without human-driven climate change, current temperatures would be 2 to 4 degrees Celsius cooler.
Neighboring countries face similar crises. In the United Kingdom, the public health agency issued its second-ever red-level heat warning as temperatures approach 30 degrees Celsius, posing life-threatening risks even to healthy individuals. Rail operators have imposed speed restrictions and advised travel only when necessary due to heat-related track issues. The National Association of Head Teachers reported that nearly all schools have adjusted schedules because English buildings are ill-equipped for such heat.
In Italy, the Ministry of Health declared a red alert in 16 major cities, including Rome and Milan. Coastal areas are expected to worsen due to high humidity, with heat indices reaching up to 45 degrees Celsius.
The Netherlands issued an orange-level warning; national rail services reduced trips on many routes, and Amsterdam’s city council offered free access to outdoor swimming pools for city pass holders to help people cool down.
This heatwave is expected to move into Eastern Europe within days. Poland anticipates temperatures may break its previous record of 40.2 degrees Celsius set in 1921. Croatia and Hungary have prepared to raise their heat warnings to the highest levels. Only Spain shows early signs of temperature decreases in some areas.
