France experienced its hottest night from Monday to Tuesday since measurements began in 1947, the national weather agency said.
The national temperature indicator – an average of readings from 30 stations across France – reached 21.6C, according to preliminary figures taken Tuesday morning. The previous record was 21.4C, set on July 25, 2019.
Key events
Nearly all of Spain was under a heat alert on Tuesday, with parts of the south and north of the country placed on the highest warning level, AFP reports.
National weather agency AEMET issued red alerts – a warning for “extraordinary danger” – for areas around the southern city of Cordoba, the northern city of Bilbao and parts of the northern region of Cantabria.
Temperatures of up to 40C in the shade were forecast in parts of the Basque Country on the border with France, an area where such extreme heat is relatively uncommon.
Large swathes of central and northern Spain were placed under orange alerts – the second-highest level– while most of the remainder of the country was covered by yellow warnings. Only areas on the coastline escaped heat alerts.

European heatwave triggers surge in electricity market prices and shuts down French nuclear plant
Jillian Ambrose
The heatwave has triggered a surge in electricity market prices across Europe this week to levels usually reserved for the middle of winter.
As millions turn to air conditioning to counter the rising temperatures, the high pressure heat dome affecting much of Europe has caused wind speeds to drop, limiting the continent’s renewable energy.
The higher temperatures also led to the unplanned shutdown of a major French nuclear plant by limiting its access to cooling water needed to run its reactors. French utility EDF expects the reactor to remain offline until temperatures return to normal next week.
The combination of rising electricity demand and falling low-carbon generation has caused prices to climb to multi-year highs.
In Germany, Europe’s biggest electricity market, wholesale prices will reach highs of €545.51 per megawatt-hour this evening, the highest since June 2024, according to the Epex Spot exchange.
In France, the price at the same time will climb to €268.67 per megawatt-hour, the highest since August 2023. UK power markets show a price of almost £230/MWh for this evening from 8pm, almost three times the average price of £86.28/MWh in June last year.

Poland is bracing for the heatwave to hit this weekend as it moves eastwards from France and Germany. Temperatures are expected to peak on Sunday, reaching up to 38C in the capital, Warsaw, and up to 41C in the Lower Silesia region.
If the forecasts are accurate, temperatures could smash the June record for Poland – 38.2C, set in 2019 – or even the all-time national record of 40.2C from 1921.
The government’s security agency, the RCB, has issued advice urging Poles to limit time spent outdoors, drink plenty of water and cover their heads when in direct sunlight.

Fire services are worried that there could be a spate of wild fires in the hot weather.
Dorset and Wiltshire fire and rescue service asked farmers and businesses to postpone “controlled” burns.
It said on Tuesday: “To reduce the risk of wildfires during these hot and dry conditions, we urge everyone to refrain from conducting prescribed or controlled burns unless absolutely essential. These fires can easily spiral out of control and spread rapidly.”
Devon and Somerset fire and rescue service issued wider advice including:
Don’t have campfires or barbecues in the countryside. Only have them in safe designated areas.
Avoid having bonfires in very dry weather. If you must have a bonfire,
Glass in direct sunlight can cause fires – ensure there is none lying around.
Here are some of the latest photos from the heatwave in Europe.

People are already paying the price for the UK government’s inaction in protecting them from the climate crisis, says Holly Brazier Tope, Director of Politics at the Green Alliance.
“We built and planned our homes and communities for a UK that isn’t this hot, and right now, people are paying the price. Schools are closing early, NHS appointments are being cancelled, trains are running late. This is the reality of climate change on our doorstep and successive governments have left people to face it unprotected. Without urgent action, 92% of existing homes could overheat by mid-century and heat-related deaths could rise to 10,000 a year.
“In the summer of 2022, we lost more people to heat than were killed on our roads in the entire year. And yet government did not act. This is not a future threat. It is here, it is now, and it is the consequence of inaction. This government must respond fast with a systemic, nationwide response that delivers smarter planning, community resilience, protection now and net zero for the future.”

London Fire Brigade (LFB) said it had responded to around 400 calls overnight, including two house fires believed to be caused by lightning strikes and flooding of homes.
Thunderstorms following soaring temperatures caused flash flooding in the capital, the LFB said as it urged drivers not to drive through flooded areas.
There is severe disruption across London’s transport network on Tuesday, in part caused by the extreme weather.
On the Elizabeth Line, heavy rain has caused flooding which means there is no service between Heathrow Terminals 2 and 3 and Heathrow Terminal 4, Transport for London said. Meanwhile, there are severe delays between Paddington and Heathrow Terminal 5 and Reading due to an earlier points failure at Southall.
There are also severe delays on the Mildmay Line, which is running a reduced service because of the hot weather.
The Metropolitan Line remains partly suspended between Baker Street and Aldgate, while the Hammersmith and City Line is also suspended between Barking and Moorgate. The entire Circle Line has been suspended, as have parts of the District Line.
The UK Met Office said 29,074 lightning strikes have been recorded in the UK in the last 24 hours to 9am on Tuesday.
All of these strikes were over England, with the majority – 18,540 – over Somerset.
The Met Office’s lightning map also shows there have been hundreds more strikes across south-east England on Tuesday morning.
The highest overnight temperature was 20.4C in Gosport, Hampshire, while eight other place recorded a tropical night, meaning one where temperatures do not fall below 20C.
These were Crosby, in Merseyside, Plymouth and North Wyke, in Devon, Aberporth, Cardiff and St Athan in Wales, Hurn in Dorset and the Isle of Wight.
