Europe’s ongoing heatwave has prompted unprecedented emergency measures across multiple countries, with Italy placing all major cities on its highest health alert and Hungary turning off lights at state buildings to conserve energy amid record temperatures.
Italy issues first-ever nationwide red alert
Italy’s Health Ministry activated its highest-level heat warning for all 27 cities under its national surveillance system on August 6, marking the first time all monitored areas have been simultaneously placed on red alert. The alerts cover cities from Palermo in Sicily to Bolzano in the north, signaling a serious health risk for the entire population. Authorities urged residents to avoid direct sunlight during peak hours, remain indoors when possible, and increase water intake. Major tourist sites, including Rome’s Colosseum and Pantheon, extended evening opening hours, installed cooling mist fans, and added medical stations.
In Genoa, residents aged 65 and older can access free entry to museums and libraries during the hottest hours of the day throughout August. Rome extended its program of free screenings in air-conditioned cinemas by 10 days, now running through August 14. The Piedmont region, centered on Turin, declared a state of emergency due to drought and wildfire risks, with rivers at historic lows.
Hungary cuts energy use as Danube levels drop
Hungary implemented nationwide energy-saving measures on August 6, including turning off decorative and non-essential lighting at state institutions, Parliament, Buda Castle, and the Chain Bridge to reduce strain on the power grid. The country’s sole nuclear plant was largely shut down after record-low water levels on the Danube—used for cooling—disrupted operations. The government also called on companies and households to curtail electricity consumption as temperatures neared 40°C (104°F) in Budapest.
Austria breaks national temperature record
Austria recorded its highest-ever temperature of 41.2°C (106.2°F) on August 5 in Bad Deutsch-Altenburg, surpassing the previous record set just a day earlier in Vienna. The national weather service, GeoSphere Austria, noted that rainfall from January to June was 27% below average nationwide, with some eastern regions receiving only half their normal precipitation. Climatologist Alexander Orlik stated that parts of the country had not experienced such dry conditions since 1885.
Wider impacts across Europe
The heatwave has disrupted energy and transport systems across Central Europe, with France and Spain still recovering from weeks of record-breaking temperatures and destructive wildfires. In Albania, emergency services battled a wildfire in the southern Mallakaster region, while the Vatican moved Pope Leo’s weekly audience indoors to shield attendees from extreme heat. Greece has also faced ongoing wildfire threats, with crews battling blazes in multiple regions.
Health and infrastructure strain
Health officials across Europe warned that prolonged exposure to temperatures above 40°C (104°F) poses severe risks, particularly for vulnerable populations. In Budapest, local authorities distributed bagged water to pedestrians, and cooling centers were opened to provide relief. The Danube’s dwindling water levels have not only affected Hungary’s nuclear plant but also raised concerns about shipping disruptions and agricultural losses in downstream countries.
Long-term climate concerns
Scientists and officials emphasized that such extreme weather events are becoming more frequent and intense due to climate change. The European Union’s Copernicus Climate Change Service has previously noted that Europe is the fastest-warming continent, with heatwaves, droughts, and wildfires intensifying in recent decades. Policymakers are increasingly linking these events to broader discussions on energy resilience, water management, and climate adaptation strategies.
Governments are also reviewing emergency response protocols to better prepare for future heatwaves, including expanded public cooling spaces, early warning systems, and cross-border coordination for energy and water shortages.
