Extreme Temperature Diary Sunday June 28th, 2026/Main Topic: Update on Catastrophic European Heatwave Ember

This is getting ridiculous.Germany has preliminarily set a new all-time heat record with 41.3°C in Saarbrücken. Until this extraordinary heatwave, the country had never recorded a temperature above 40°C in June. More extreme heat is expected this weekend.

The State & City of #Berlin may reach an average area temperature near 106° Sunday. Other cities nearby could spike to 108/109°. Not only would these break the #Germany  all-time record (again – prob 3 days in a row) it would also be a ~4 sigma event making it virtually impossible… 1/

France records around 1,000 additional deaths as extreme heat breaks European records

BERLIN (AP) — France saw around 1,000 additional deaths last week at the height of its record-smashing heat wave, the country’s public health agency said Sunday, as the head of the World Health Organization warned that Europe is now the fastest-warming continent and needs to do more to protect its citizens.

Temperature records were toppled in several countries on the weekend, wildfires were sparked in Germany and Berlin police used water cannons to cool down the crowds.

Meanwhile, the heat wave slowly moved toward eastern parts of the continent.

Germany marked a new record for the third day in a row with 41.7 degrees Celsius (107 degrees Fahrenheit) in Neißemünde, near the border with Poland, which baked under its new all-time high of 40.5 C (104.9 F). The Czech Republic also experienced its hottest day ever with 41.9 C (107.4 F), up from the previous record of 40.9 degrees Celsius (105.6 F) on Saturday.

new study from the World Weather Attribution, a Europe-based collaboration of scientists, reported Friday that the record-breaking heat and humidity in Europe this past week would not have been possible without climate change.

The rapid study found that the heat would have been virtually impossible just five decades ago, and is 200 times more likely today than it would have been 20 years ago.

France records surge in deaths during heat wave

France reported a surge in deaths last week, including a sharp increase at private homes, especially in the Paris region, the national public health agency said Sunday.

There were more than 1,200 deaths on Wednesday, when France was sweltering under its hottest temperatures, increasing to more than 1,400 deaths on each of the two following days, Public Health France said. In April and May, before the heat wave, France’s rate of deaths was about 900 to 1,000 per day.

The agency concluded that France experienced a total of at least 1,000 additional deaths during those three days alone, an estimate it cautioned is likely to increase as more data is collected, including for deaths at home.

The increase was sharpest in areas under red warnings of extreme heat, it said. Those warnings blanketed about three-quarters of the country at the peak of the heat wave. The agency said that 85% of the deaths involved people aged 65 and above.

Europe is the fastest-warming continent, WHO warns

“Europe is the fastest-warming continent on Earth, heating at twice the global average,” WHO Director-General Tedros Adhanom Ghebreyesus said Sunday on X. “Right now 150 million people are living under extreme heat, hundreds have died, schools are shut, grids are buckling.”

Driven by climate change and global warming, the “once-in-a-generation” heat wave is now occurring nearly every year, Tedros said, adding that more than 1,300 excess deaths have been recorded since June 21 linked to high temperatures in Europe.

“Heat stress is often called the ‘silent killer’ — and European homes, workplaces and schools were not built for these temperatures,” Tedros warned as he called on European countries to implement action plans. He said they should focus on preparedness, prevention and stronger health system responses.

Lightning strikes Swedish theme park

In Sweden, several people were injured when they were hit by lightning at an amusement park, the country’s TT news agency reported.

Three adults were taken to the hospital, among them a woman with serious injuries, after the lightning struck the Tosselilla Sommarland park in Tomelilla in the south of the country.

Across Europe, the extreme heat has been followed by severe thunderstorms.

Denmark, which marked new temperature records on Saturday, recorded 1,156 lighting strikes by Sunday morning, according to public broadcaster DR.

Heat sparks wildfires in forests contaminated with WWII ammunition

In Gohrischheide, in eastern Germany, a fire broke out in a large forest that’s still contaminated with ammunition from World War II, complicating efforts by firefighters.

Similarly, a major firefighting operation was underway in southwest Germany near the village of Traisen, where the heat sparked a forest fire in an area that also contained unexploded ordnance. Firefighters had to stop work temporarily after explosions took place and an ordnance disposal unit was brought in to continuously assess the situation, German news agency dpa reported. Some 650 people in Traisen had to leave their homes Sunday afternoon because the fire continued to spread.

Fire departments in the big cities were busy sending out ambulances to people suffering from heat-related illnesses. In Berlin, an additional 500 ambulance dispatches were reported on Saturday, most of them heat-related.

Berlin police use water cannons to cool down locals and tourists

The German capital’s police found a way to help suffering Berliners and tourists alike. They put up two huge water cannons — usually used to disperse unruly protesters — in front of the iconic Brandenburg Gate and sprayed the cool water across the cheering crowd.

The heat also worsened damage to infrastructure, with the concrete surface on countless highways breaking up, and a weekend warning by national rail operator Deutsche Bahn to avoid all unnecessary train travel.

More than 600 passengers had to be evacuated from an overheated train in Brandenburg after a tree fell onto an overhead power line during a storm on Saturday evening. The train, which was on its way from Hamburg to Prague, lost power. The air conditioners stopped working and the doors were locked until emergency responders forced them open. Two people were hospitalized with heat-related problems, dpa reported.

In the eastern city of Leipzig, no trams will be running until early Monday morning due to heat damage to tracks and switches. The Leipzig Public Transportation Authority said that the high temperatures had caused the joint sealant for asphalt and concrete in switches and tracks to run and clump together in many places throughout the city’s network.

Heads up‼️ Hottest Ever?! It’s genuinely possible. No exaggeration to say that the severity of the #heatwave the East US is about to experience will be cruel/ grueling for days! 100s of record highs, some neck and neck with the hottest ever in the East Coast cities! Peak heat index numbers near 115.

‼️ Hottest Ever? It’s possible! The situation is escalating on the Eastern Seaboard/ I-95 corridor for late week. NOAA is forecasting peak highs close to the hottest ever measured. All-time highs from NYC to Baltimore/DC to Raleigh etc… are in the 103-107 range and in many cases the forecast is close

As @extremetemps.bsky.social has documented, all time-record high temps in northwest Siberia past couple of days. Beliy Island (73.3ºN) hit 28.3C (83F), apparently the highest temp so far north anywhere in the world. But this heatwave is distinct from the European heatwave. #Arctic #ExtremeWeather

Rick Thoman (@alaskawx.bsky.social) 2026-06-27T17:08:50.428Z

"blame the victim" (in this case, the french people who traditionally have not needed air conditioning) is a classic #NewClimateWar (bookshop.org/p/books/the-…) tactic.

It’s easier to snidely imply that heatwave victims brought suffering upon themselves, rather than report the sobering reality that nations are not prepared for deadly fossil fuel-driven climate impacts now spreading misery and wreaking economic havoc, despite decades of climate scientists’ warnings
