A heatwave gripping Central and Northern Europe is set to intensify this week, with meteorologists warning of temperatures soaring to 35°C in urban areas by Friday. The German Weather Service (DWD) and Austria’s Central Institute for Meteorology and Geodynamics (ZAMG) confirmed that the mercury will climb from Wednesday’s 30°C to peak on Friday, though the heat will be punctuated by severe thunderstorms.
The sudden shift follows a cool, unsettled weekend across much of the continent. In Germany, the so-called *Schafskälte*—a late spring cold snap—brought unseasonably chilly conditions before giving way to the incoming heatwave. The Tagesspiegel noted that while Monday will start predominantly grey, “from Wednesday, hot air masses will push temperatures to over 30°C in places.”
Across the Alps, Austria is bracing for the most intense heat. The *Der Standard* reported that Vienna and other major cities could see 35°C on Friday, accompanied by “repeated thunderstorms” that may bring localized flooding. The storms are expected to develop as humid, energy-rich air masses collide with cooler fronts, increasing the risk of violent downpours and hail.
Further north, Sweden’s meteorological agency (SMHI) warned of a dramatic turn by Midsummer weekend, when temperatures could trigger “powerful thunderstorms” across the country. SMHI meteorologist Max Lindberg Stoltz described the incoming air mass as “very moist and energy-rich,” heightening the potential for severe weather.
The Netherlands and Belgium are also transitioning from a cool, showery start to June to a warmer pattern by late week. Dutch meteorological service KNMI forecast that temperatures will rise above 25°C nationwide from Thursday, with local peaks exceeding 30°C. However, the agency cautioned that the warm spell may be short-lived, as early July signals remain uncertain.
In Eastern Europe, Romania and Hungary are already grappling with the consequences of the unstable weather. Romania’s National Meteorological Administration issued a yellow alert for wind gusts and hail across much of the country on Sunday afternoon, warning of torrential rain and potential flooding in the west, central, and mountainous regions. Meanwhile, Hungary’s meteorological service (Hungaromet) cautioned that supercells could form in the south, producing hailstones larger than 4cm and winds up to 100 km/h.
The extreme weather has already disrupted daily life. In Sweden, thousands remain without power after Sunday’s storms, with local media reporting outages affecting multiple counties.
Health authorities across the affected regions are urging residents to take precautions. Public health officials in Austria and Germany recommend limiting outdoor activities during peak heat hours, staying hydrated, and checking on vulnerable neighbors. The German Red Cross has activated heatwave response plans in urban centers, while Austria’s health ministry has issued guidelines for hospitals to prepare for heat-related illnesses.
As the continent braces for a week of volatile weather, the contrast between the lingering cool snap and the impending heatwave underscores the growing unpredictability of Europe’s summers.
