Heatwave conditions that have left Spain, France and the UK sweltering for days are set to shift to the east, with forecasters in Germany and the Czech Republic warning of extreme conditions.
Temperatures in Germany could hit 40C in some western and south-western areas on Thursday, and across the country on Friday. An extreme weather warning is now in place in much of the Czech Republic.
In France, Prime Minister Sébastien Lecornu announced the health alert level is being raised to its highest, to boost hospital staffing and protect the vulnerable.
Health Minister Stéphanie Rist said they were now seeing deaths linked to the extreme temperatures among “young people who suffer cardiac arrests”, as well as the elderly.
United Nations climate change chief Simon Stiell has said “Europe’s savage heatwave has the fingerprints of the climate crisis all over it”, and he has called for “a faster shift to renewables, protecting forests and boosting climate resilience”.
After Francerecorded its hottest day on Wednesday for the second day in a row, records continue to be broken. Météo-France said the average minimum temperature reached 22C on Wednesday night. Nantes saw 27.2C in the north-west.

After days of high temperatures in Paris, the health minister said the ambulance service in Paris had seen four times more cardiac arrests than normal over a 24-hour period, although she stressed there were no confirmed figures for the number of deaths linked to the heatwave.
Paris mayor Emmanuel Grégoire said the mortality rate was on the rise in the capital.
“We must not believe ourselves to be invulnerable,” he told French TV. “I am thinking especially about the youth… At about 19:30 last night… I saw 100 or so joggers on the street. Frankly, that’s irresponsible.”
“It’s fine to take a couple of days off from exercising,” he added.

Meanwhile, a three-year-old child has been found dead in a car in the Paris region, days after two young children were found dead in the family’s car in the southern town of Carpentras.
In the north-western city of Rennes, the head of the Accident and Emergency department Professor Louis Soulas linked the deaths of five or six people in their homes in the region to the extreme temperatures.
Emergency services had gone to check in on them after they had failed to pick up their phones during welfare calls, said Soulas: “It’s not just the very elderly; it’s people aged 60 and up.”
Rennes saw a record 40.6C on Monday, only for that to be broken by 41C the following day. The previous record dated back to 2022.
The region’s intensive care units were “saturated,” he warned. “We are truly at a peak of activity.”
Sébastien Lecornu said France’s Orsan health emergency plan was now moving to level three so the health system could “withstand the strain over time and protect the most vulnerable”.
French teachers’ unions are calling for a strike in response to “unacceptable working conditions” in the heat. They said that despite having called for mitigation measures to be taken “nothing was done” and the “health of staff, students and their working conditions are being jeopardised”.
Three nuclear plants in France have gone offline due to the heat.
Some western regions are now bracing for huge thunderstorms from Thursday afternoon onwards.

Climate change is driving up temperatures around the world – but particularly in Europe. It is the fastest warming continent, heating up twice as fast as the global average, according to the Copernicus climate service.
This is causing increased summer heatwaves, greater pressure on Europe’s water supply, and more intense wildfires. Last year, more than 1 million hectares burnt across Europe – a record level – with Spain particularly affected.
Although temperatures in Spain are set to peak at 38-39C in some areas on Thursday, forecasters say a cooler mass of Atlantic air is coming in, after the highest June temperatures were recorded this week, with 45.1C in the southern town of Andújar on Monday.

Italians have been experiencing high temperatures since the start of this week – but the peak of the heat is expected for Monday, when 40C are expected in various northern regions.
Night-time temperatures in those areas might not drop below 29C.
“Gone are last century’s June days of 32C daytime temperatures and cool 17C nights,” forecaster Lorenzo Tedici told Italian media.
“We have become so accustomed to excess that, paradoxically, today we welcome a forecast of 34C as good news.”
