Italy placed major cities under the highest heat alert as a severe heat wave affected Europe. This weather event set a new temperature record in Austria and fueled wildfires in France. It also disrupted energy and transportation across the continent. Temperatures have soared above 40 Celsius (104 Fahrenheit) in multiple countries.
Scientists and officials indicate these extreme weather events are becoming more regular and intense due to climate change. The current heat wave exposed vulnerabilities in public health systems, power generation, transportation networks, and tourism infrastructure. Governments and businesses faced the challenge of adapting to these frequent extreme weather periods.
Italy’s Nationwide Red Alert
Italy’s Health Ministry issued a red alert for all 27 cities under its hazardous heat surveillance system. This marked the first time this year that the entire network was at the highest warning level simultaneously. The alerts ranged from Trieste in the northeast to Palermo in Sicily. They indicated a health risk for the broad population, not just vulnerable groups like older adults and those with chronic illnesses.
Authorities advised residents and tourists to avoid direct sunlight during peak heat hours, stay indoors when possible, and drink plenty of water.
The intense heat caused alterations at key tourist spots. Rome extended evening hours at landmarks such as the Colosseum and Pantheon. Additional facilities like cooling mist fans were set up at the Colosseum entrances. Rome introduced an “urban beach” along the Tiber River in the Marconi neighborhood for relief from the heat. Known as Tiberis, the spot provided an escape for families and children from the city’s scorching environments.
Temperature Records in Austria and Slovakia
Slovakia recorded a new all-time high temperature at 42.2 C (108 F) in Dolne Plachtince. The Danube’s low water levels led to operations halting at the main hydroelectric power plant in Gabčíkovo. So far this year, electricity production has dropped 15% due to the Danube’s water shortage.
Austria recorded a high temperature of 41.2 C (106.2 F) in Bad Deutsch-Altenburg. Severe drought compounded issues, with rainfall 27% below average nationwide. Some areas experienced the driest conditions since 1885.
Drought Impacts Hungary’s Nuclear Power Plant
In Hungary, drought and low levels of the Danube hindered the sole nuclear power plant. Operators reduced production by about 10%, leading to emergency conservation measures. Major industrial users and households were asked to reduce electricity consumption, particularly during peak hours between 5 p.m. and 10 p.m.
The heat wave led to record temperatures, with Budapest reaching its warmest overnight temperature at 28 C (82 F). Several major companies, including Mol, Gedeon Richter, and automotive manufacturers, adjusted electricity use strategies. The government canceled parliamentary sessions to save power.
Germany’s Concerns and France’s Wildfire Risks
Germany confronted drought effects on transportation and industry due to low water levels in the Rhine and other rivers. Transport Minister Steffen Bilger met with organizations to address challenges to inland waterway shipping and logistics. The environmental organization BUND urged a focus on improving river resilience to climate change.
In southeastern France, authorities maintained a large firefighter presence to address wildfire risks. A significant wildfire had previously burned over 60 square kilometers. Authorities warned of high potential for reignition due to winds and dry conditions.
Heat Wave’s Effect Across the Balkans and England
The Balkans faced the heat wave with temperatures nearing 40 C (104 F). Serbia battled wildfires, including one in pine forests near Belgrade. Another significant fire emerged near Kraljevo, complicated by challenging terrain.
Temperatures in coastal Croatia prompted tourists in Dubrovnik to seek shade during the hottest parts of the day. Meanwhile, England’s cool down was offset by grass fires, which temporarily closed a runway at Heathrow Airport.
