Record Heat Grips Central and Eastern Europe, Straining Power and Water Systems

A severe heatwave has pushed temperatures to record highs across central and eastern Europe this week, breaking heat records in Slovakia, Austria and Hungary, forcing Poland to shut down two coal power plants, and prompting Italy to place all 27 of its major cities on the highest heat alert. Falling river levels have cut nuclear and coal power output, disrupted shipping, and contributed to an early wine harvest in France as drought and heat combine to strain infrastructure across the continent.

How hot did it get, and where?

Slovakia recorded a national high of 42.2C (108F) on Thursday in the southern village of Dolne Plachtince, according to the Slovak Hydrometeorological Institute. Austria’s weather agency reported an all-time national record of 41.2C (106.2F) on Wednesday in Bad Deutsch-Altenburg, near the Slovak border. Hungary didn’t set a daytime record but logged an unusual overnight one: temperatures in Budapest only fell to 28C (82.4F) on Wednesday night, a sign of how persistent the heat has become. In South Korea, separately, temperatures reached 42.5C amid its own record heatwave.

What’s happening to power and water supplies?

Low river levels are hitting energy production across the region. Slovakia’s only nuclear plant is running at just 80 percent capacity because of record-low water levels on the Danube. Hungary’s sole nuclear plant, which normally supplies about half the country’s electricity, was down to 10 percent capacity, though Prime Minister Péter Magyar said on X that one of its turbines was coming back online, citing the Danube rising nine centimeters above its recent low point and expected rain in Austrian catchment areas. He still urged voluntary electricity cutbacks for the day. In Poland, authorities shut the Kozienice and Połaniec coal-fired plants after the Vistula River’s water level became too low to supply cooling water, removing about 1.3 gigawatts from the national grid. Polish Prime Minister Donald Tusk had already urged employers to provide air conditioning and cold water for workers. In Germany, a worsening drought has pushed companies to move cargo by road instead of by ship, reducing shipping volumes and pushing up prices.

Is the heat causing deaths?

Yes. Italy’s health ministry, which placed 27 cities from Trieste to Palermo on red alert ahead of the weekend, warned residents to avoid direct sun between 11am and 6pm; a 19-year-old tomato picker is among at least four people believed to have died from the heat there in recent days. In Germany, the Robert Koch Institute estimates roughly 11,900 heat-related deaths nationwide this summer. Climate activists from Fridays for Future demonstrated outside the German chancellery, with organizer Annkatrin Schwirten arguing that fossil fuel policy is driving “extremely dangerous” heat and that thousands of heat deaths a year should not be treated as normal.

How is this affecting farming and other industries?

French winegrowers, including in the Bordeaux region, began harvesting grapes on Thursday — unusually early after a summer of repeated heatwaves, drought and wildfires. One grape-picker told the newspaper Sud Ouest that normally the harvest crew would still be on vacation at this point in the year. Winemakers say the heat won’t hurt wine quality, but the shift reflects a broader trend of climate change pushing harvests earlier and pushing some French farmers toward crops that need less water.

Where do the sources place blame or emphasis?

Coverage generally agrees the heatwave is part of a longer pattern tied to the warming climate, but outlets differ in what they highlight. The Guardian gives the most space to activists and environmental groups directly linking the crisis to fossil fuel policy, quoting both a Fridays for Future organizer and Paweł Pomian of the Polish group EKO-UNIA, who argues power plants that help drive climate change are now becoming its victims and calls for faster investment in wind and solar, which need far less water to generate electricity. Al Jazeera focuses more on the scale of disruption and human toll in Italy and the broader claim that Europe is warming twice as fast as the global average. France24 devotes a separate report to the ripple effects on French wine harvests, an angle the other outlets don’t cover at all.

Why does this matter beyond this week’s weather?

Scientists cited across the coverage warn that this kind of extreme summer heat risks becoming the norm in Europe, which they say is heating up faster than any other continent. The current strain — on nuclear and coal plants that depend on river water for cooling, on shipping routes that need minimum water depths, and on farming calendars tied to seasonal temperatures — illustrates how infrastructure built for a cooler climate is increasingly mismatched with the conditions it now has to handle. The combination of falling river levels, cascading power plant shutdowns, and rising heat deaths suggests these disruptions may recur in future summers rather than remaining one-off events.
