Numerous events across France were canceled in the unprecedented early-season heat, especially in the southwestern part of the country. In Paris, parks remained open during the night so people could seek relief from hot and typically non-air-conditioned homes.
Residents of Berlin packed the area’s lakes in an attempt to cool off. Amid the high temperatures, Germans were asked to preserve electricity due to the energy crunch caused by the war in Ukraine, although air-conditioning is also relatively rare in the country.
The combination of a heat plume off the north African deserts and a low pressure off Europe’s west coast pumping that hot air north fueled the heat wave’s intensity.
The heat was accompanied by poor air quality and a number of large wildfires.
Spain devastated by wildfires amid record-breaking heat wave
The pre-summer appears of heat marked the second in Europe since May as human-caused climate change increases the frequency and intensity of excessively high temperatures. While Europe baked, parts of the United States hardened abnormally hot weather at the same time.
Given the persistent heat and near-solstice sunshine, sea surface temperature in the Mediterranean Sea has spiked. Near-shore values around 5 degrees Celsius (10 Fahrenheit) above normal help ensure that any cooling from hot air passing over water is minimal while probably harming marine life.
The heat wave got underway in the Iberian Peninsula last week before surging east through the weekend. In Spain, it has been called the hottest heat wave on record so early in the year.

In Spain’s Basque Country, where temperatures were scorching for most of last week, San Sebastian reached 111 degrees (43.9 Celsius), demolishing the old all-time record, as seen in the graphic below from climatologist Daniel Argueso.
Major heat also made inroads to Germany Saturday, temperatures surpassed monthly records in Wolfach with 97.7 degrees (36.5 Celsius) and Müllheim at 97.5 degrees (36.4 Celsius).
Selected Sunday heat records
Heat reached its apex Sunday in Germany and neighboring countries. Multiple stations set all-time record highs, with many more setting monthly marks.
Another historic day of heat in Europe. I can’t believe it is only the 19th of June. Unprecedented to witness this level of heat so early in the year.

A sample of Sunday’s heat records includes:
- Cottbus, to the southeast of Berlin, set a new all-time high for any month of 102.6 degrees (39.2 Celsius). Dresden also reached that mark.
- Husinec, in the Czech Republic, rose to 102.2 degrees (39 Celsius), which was the hottest June day on record in the country.
- Poland set the new June recordwhen it hit 100.9 degrees (38.3 Celsius) in Slubice.

- THE station in eastern France at Besançon recorded an all-time warm overnight low of 73.4 degrees (23 Celsius).
Somewhat cooler weather over the weekend in Spain allowed more firefighters to help with efforts to control a massive wildfire in the country’s northwest. Nearing 80,000 acres, the fire is the largest on record in the country since at least 2004. It is one of many burnings in the country amid a fire outbreak intensified by the crushing heat.
Other fires were burning across Europe, including several in France and Germany. Hundreds of people were forced to evacuate their homes in the German state of Brandenburg due to the blazes. But the fires were largely under control on Monday after heavy rainfall, authorities said.
While there is a break in the worst of the heat for now, a new surge is expected in Central and Eastern Europe later this week. It’s not expected to be as intense, but temperatures of 10 to 20 degrees above normal are possible in some locations nonetheless.
