Southern Europe is grappling with a severe heatwave this week as temperatures soar beyond 40°C (104°F) across several nations, prompting red alerts, travel disruptions, and widespread safety warnings. Tourists and residents alike in Spain, Italy, France, Portugal, Turkey, and Croatia are enduring one of the most extreme weather events of 2025, with heat-related incidents and infrastructure strain reported in multiple regions.
Meteorological agencies across Europe have issued extreme weather warnings and public health advisories as the continent’s most popular tourist destinations become dangerously hot during the peak summer travel season.
Spain: Record-Breaking Temperatures and Wildfire Risks
Spain has been among the hardest-hit countries, with the Spanish State Meteorological Agency (AEMET) reporting highs of 46°C (114.8°F) in parts of Andalusia, Madrid, and Extremadura. Several provinces remain under red alert, with authorities urging both locals and tourists to avoid outdoor activity during midday, remain hydrated, and check in on elderly relatives or those with pre-existing health conditions.
The intense heat has elevated wildfire risks, particularly in the southern and central regions. Emergency services have been deployed to combat blazes, and certain rural areas have seen preventive evacuations. Hospitals in Madrid have also reported a spike in heatstroke-related admissions.
Italy: Rome, Milan, and Palermo Under Heat Red Alerts
Italy is battling similar extremes, with 18 major cities including Rome, Milan, Naples, and Palermo under red alert status by the Italian Ministry of Health. The capital recorded temperatures reaching 40°C, disrupting daily life, stressing transport systems, and increasing the burden on healthcare services.
Hospitals have issued advisories to vulnerable populations, especially seniors and children. Outdoor events in many cities have been postponed or canceled. In Venice, authorities are limiting water taxi traffic during peak hours to protect passengers from heat exposure.
France: School Closures and Environmental Restrictions
France is experiencing its most intense canicule (heatwave) in years, with Paris projected to hit 39°C (102°F). The government has declared red alerts in 16 departments, while 68 others remain under orange alerts. Over 1,300 schools have been shut across the country to safeguard children from extreme heat.
In a rare move, one of the country’s nuclear power plants was temporarily shut down due to overheating risks. Train travel between France and Italy has been suspended following mudslides and heat-induced storm activity. Meanwhile, traffic regulations are in effect across several cities, banning high-emission vehicles and reducing speed limits to mitigate heat-related pollution.
Portugal: Historic Heat Records and Ongoing Fires
Portugal has not been spared, with the national temperature record for June shattered as Mora registered 46.6°C (115.9°F). The Portuguese Institute for Sea and Atmosphere (IPMA) has issued red heat warnings in Lisbon, Évora, and Beja, where authorities have advised residents to stay indoors during the hottest hours.
Several wildfires are active in central and northern Portugal, prompting emergency evacuations and mobilizing hundreds of firefighters. The dry and windy conditions are exacerbating the spread, with helicopters and air tankers being used to support ground teams.
Turkey: Mass Evacuations as Wildfires Spread
In Turkey, the provinces of Izmir and Manisa are contending with raging wildfires, intensified by dry vegetation, high temperatures, and strong winds. Over 50,000 residents and tourists have been evacuated from high-risk zones. The government has deployed military and emergency response teams to contain the flames and provide shelter and medical assistance to affected communities.
The Turkish Meteorological Service continues to monitor heat indexes that have surpassed 43°C in coastal and inland regions.
Croatia: Coastal Heat Puts Pressure on Infrastructure
Tourism-heavy Croatia has issued red weather warnings for several Adriatic coastal cities, including Split, where the temperature reached 35°C (95°F). While lower than elsewhere in Southern Europe, the sustained heat has led to increased demand for electricity and water, straining urban infrastructure.
The Croatian Meteorological and Hydrological Service has cautioned visitors to avoid peak-hour sun exposure and stay hydrated. In Dubrovnik and Zadar, shaded cooling stations have been set up in public squares for tourists and locals alike.
Climate Change and Future Projections
Meteorologists and climate scientists point to a concerning trend: global warming is amplifying the intensity and frequency of summer heatwaves across Europe. According to data from the European Environment Agency, the Mediterranean region is one of the most climate-vulnerable zones globally, with projections indicating longer and more dangerous summers ahead.
Extreme temperatures are becoming the new norm during peak tourist seasons, forcing cities and governments to adapt their emergency planning, infrastructure, and tourism management.
Travel Advisory and Safety Recommendations
Tourists currently in or planning to visit Southern Europe are urged to monitor official weather bulletins, follow local government advisories, and prepare for potential transportation disruptions. Key travel safety tips include:
- Limit outdoor activities between 11 a.m. and 4 p.m.
- Wear lightweight, breathable clothing and use sunscreen
- Drink water frequently, even if not feeling thirsty
- Use air-conditioned spaces like hotels, cafes, and museums
- Check with airlines for flight schedule changes due to heat or wildfires
Many regional transit systems are also operating with adjusted schedules or reduced services during midday hours due to track and road surface heating.
Conclusion
Southern Europe’s 2025 summer heatwave is a stark reminder of the climate-related challenges facing popular tourist regions. With temperatures exceeding 45°C, cities across Spain, Italy, France, Portugal, Turkey, and Croatia have entered emergency mode, issuing red alerts to protect public health and infrastructure. As climate extremes become more common, tourism planning will need to evolve—prioritizing sustainability, safety, and adaptability for future travelers.
