France Records Hottest Day Ever as Europe Heatwave Intensifies
France logged its hottest day since records began in 1947 as a North African heat mass smothered western Europe, prompting red alerts across multiple countries.

Workers sweated in choking heat and pupils stayed home on Tuesday as an early-summer heatwave smothered much of Europe, with France suffering its hottest day on record.
Schools and tourist sites closed early, and railways canceled journeys as several countries issued red alerts for much of their territory in the record-breaking heat.
“It’s getting a bit more unbearable, it’s hot,” said Vadim Bobu, a 31-year-old building worker laboring on a construction site in Paris. “We don’t have a choice, we have to pay the bills,” he said.

France, the worst hit, on Tuesday had its hottest day since measurements began in 1947, the national weather agency said, after sweating through its hottest night ever recorded. The national temperature indicator — an average of daytime and nighttime temperatures across 30 stations — reached 29.8 °C, Meteo-France said, citing provisional data.
Scientists have shown that recurring heatwaves are a clear marker of global warming, and warn they are set to become more frequent, longer and more intense, driven by humans’ burning of fossil fuels.
In Spain’s capital Madrid, Carmen Loayza, a 50-year-old homemaker, said the heat brought on headaches and she tried not to shout at her children. “But the heat gets to me, it overwhelms me,” she said.

Heat Health Danger
Nearly all of Spain was under a heat alert, with parts of the south and north on the highest warning level for “extraordinary danger”, national weather agency AEMET said.
As in various countries, authorities urged citizens to take extra care of vulnerable people, drink water and avoid exertion at the hottest hours. But some workers said they had no choice but to sweat in the sun.
Removal man Valentin Fernandez told AFP he was having a “rotten time” trucking furniture and boxes in Madrid, where the temperature reached 38 °C. “When the sun starts to hit you, you feel like dying. And inside the truck it’s twice as bad… it’s horrendous,” he said, sweat soaking his shirt and running off his nose.
A lack of air conditioning at some of Spain’s hospitals prompted the SATSE nurses union to issue a statement denouncing conditions that put workers and patients at risk. Temperatures “reach and exceed 30 °C in areas” of hospital facilities, it said, while noting authorities had only recommended that staff “close the windows and lower the blinds as much as possible.”
Italy’s health ministry declared a red heatwave alert in 15 cities including Milan and Rome. Blackouts struck Milan and Turin because of the spike in air conditioning use.
UK Schools Close
A massive front of hot air from North Africa was smothering western Europe, Sebastien Leas, a forecaster at Meteo-France, told AFP. A cold front off Portugal was “acting like a heat pump, drawing up warm air,” he said. “At altitude, high-pressure systems exert pressure on this warm air mass, and when we compress a warm air mass, we actually make it even hotter.”
In England, dozens of schools closed early on Tuesday and were to remain shut for two more days. “Most of our buildings cannot be cooled adequately, and there is little shade outside,” one school in the southeastern county of Buckinghamshire said.
The UK’s Met Office issued a rare red heat warning — only the second time it has done so — for parts of central and south England on Wednesday and Thursday. Temperatures could soar to 40 °C, unprecedented for the time of year — a “sobering” prospect, according to Met Office chief scientist Stephen Belcher. The railway line connecting northeast England to London issued a “do not travel” advisory.
‘Suffocating’
Speaking at a crisis meeting, France’s Prime Minister Sebastien Lecornu said 40 mostly young people had drowned since the heatwave started on June 18. In Germany on Monday, police said five people had died in fatal swimming accidents over the weekend.
In Paris, some tourists said their visit was an ordeal. “We’re suffocating in the streets, we’re suffocating in the subway, and we’re even suffocating in our rental accommodation,” said John Beeler, a 45-year-old American accompanied by his wife.
Workers at a site of automaker Stellantis near the French city of Mulhouse said they would be ending their shifts early from Tuesday to Sunday in protest at working conditions during the extreme heat. “Temperatures in some workshops are close to 38–40 °C,” union representative Salah Keltoumi said. “You’re there assembling parts, but with people who turned up exhausted because they couldn’t sleep properly the night before.”
Austria, Poland, Hungary and Croatia each issued heat warnings for parts of their territory, and emergency services in Hungary and Slovenia reported elderly people seeking help as the heatwave continued to tighten its grip across the continent.
