Europe is currently experiencing a major heatwave, shattering temperature records across the continent and bringing extreme conditions to the UK. This unprecedented early summer heat is causing significant disruption, impacting public health, infrastructure, and the environment, and is being strongly linked by scientists to ongoing climate change. Authorities are issuing widespread warnings and implementing emergency measures as sweltering conditions persist.
Record-Breaking Heat Grips Europe and the UK
An intense high-pressure system has delivered Europe’s first major heatwave of the summer, pushing temperatures up to 10°C higher than average for this time of year. The scorching conditions began across the Iberian Peninsula and have spread rapidly, affecting millions across popular destinations like France, Italy, Germany, and the Balkans, alongside northern countries like the UK, Switzerland, Belgium, and the Netherlands.
The scale of record-breaking heat is stark. Portugal recorded a new highest-ever June temperature of 46.6°C (115.9°F) in Mora. Spain also saw its hottest June on record, with an average temperature significantly above the historical norm, and a peak of 46°C (114.8°F) in El Granado. Cities across Spain, including Seville and Barcelona, have experienced oppressive overnight temperatures remaining above 26°C (79°F).
In the UK, specifically England, June 2025 was confirmed as the warmest on record since data began in 1884. The UK as a whole saw its second warmest June. On Tuesday, the heatwave culminated in England recording its hottest day of 2025 so far, with temperatures reaching 33.9°C (93°F) in Writtle, Essex, surpassing earlier highs in Kent. Central London also saw 33.6°C (92.5°F). Forecasts suggested highs could hit 35°C (95°F) in the South East.
Across continental Europe, temperatures have soared. France saw many cities record their hottest June nights and days, with Paris, Tours, and Bourges hitting 38°C (100.4°F) and Durban-Corbières reaching 41.5°C (106.7°F). Germany anticipates temperatures nearing 40°C (104°F). Brussels peaked at 37°C (98.6°F). The Netherlands issued severe warnings, with inland areas expected to reach 39°C (102.2°F). Even mountainous Switzerland saw its zero-degree altitude rise above 5,000 metres (16,400 feet), a phenomenon rarely seen before 2022, impacting glacial melt and landslide risk.
Widespread Impacts on Daily Life
This intense heatwave is causing significant disruption and posing serious challenges across the continent. Public health is a primary concern. Extreme heat warnings have been issued in many regions, including amber heat health alerts extended across parts of the UK. Italy issued the highest heat alert for 21 cities, advising regions to avoid outdoor exposure during peak heat. Sadly, at least two deaths have been linked to the heat in Italy and one in Spain, underscoring the ‘silent killer’ nature of extreme temperatures. Hospital admissions increased in Italy’s Tuscany region.
Infrastructure and services are also under strain. In France, Paris and 16 other regions were placed under red alert, the highest warning level. This led to measures like banning polluting traffic and implementing speed restrictions. Over 1,350 schools and colleges in red alert zones were closed or partially closed in France due to dangerously hot classrooms. Parents in Paris were advised to keep children home. Italy implemented bans on outdoor construction and quarry work during the hottest hours in several regions.
Public attractions and events have been affected. The top of the Eiffel Tower in Paris closed early. The Atomium monument in Brussels also closed early due to high internal temperatures. Outdoor events like Wimbledon saw spectators using fans to cope with the heat. Travel has also faced disruption; a power failure affected train services in Seville, and unrelated but concurrent severe storms in southeastern France suspended the Paris-Milan high-speed rail line.
Environmental consequences are severe. The heat, combined with dry conditions and strong winds, is fueling widespread wildfires, particularly across Turkey, Greece, and Montenegro, leading to tens of thousands of evacuations in Turkey alone. Low water levels in Germany’s Rhine River due to the heat are impacting cargo shipping. Glacial melt in the Alps is accelerating, increasing the risk of landslides.
The Climate Change Connection
Scientists and international organizations are explicitly linking this extreme heatwave to human-caused climate change. The UN’s World Meteorological Organization (WMO) stated that the world must adapt to more intense and frequent heatwaves in the future. They highlight that while severe, this episode is not entirely unprecedented in scale for later summer months, but its early arrival points to a worrying trend.
The WMO emphasizes that extreme heat is preventable with existing knowledge. Human-caused climate change makes heatwaves 100 times more likely, according to scientists studying a previous UK heatwave. Rising global average temperatures, particularly the warming of the Mediterranean Sea, reinforce heat domes over land. The EU’s Copernicus service notes Europe is warming at twice the global average rate.
Experts explain that increased greenhouse gases trap heat, making it harder for the planet to cool down. This amplifies moderate heat events into extreme ones. Germany’s meteorological service linked a record low rainfall period to higher average temperatures, increasing water demand and exacerbating drought. The UN Human Rights Chief warned that rising temperatures threaten various human rights, emphasizing the need for climate adaptation strategies. UN Secretary-General Antonio Guterres declared, “Extreme heat is no longer a rare event – it has become the new normal.”
Cities and individuals are adopting various coping mechanisms. European cities are exploring creative ways to help residents, including free access to air-conditioned museums or public pools, adopting ‘tropical schedules’ with shorter work hours, and setting up ‘climate oases’ with cooling facilities. Individuals are resorting to fans, cold towels, staying hydrated, and adjusting routines to avoid peak sun exposure. Discussions in Germany are also underway regarding legal rights to time off during extreme heat and mandated workplace temperature limits, highlighting the economic impact of heat-related sick days, which have surged in recent years.
Frequently Asked Questions
What record temperatures did the Europe heatwave break?
This intense Europe heatwave shattered several records. Portugal recorded its highest ever June temperature at 46.6°C. Spain also had its hottest June on record, peaking at 46°C. In the UK, England experienced its warmest June on record, and Tuesday saw the hottest day of 2025 at 33.9°C. Many cities across France recorded their hottest June night and day temperatures, with cities like Paris hitting 38°C and Durban-Corbières reaching 41.5°C.
How is the extreme heatwave impacting daily life across Europe?
The extreme heatwave is causing widespread disruption. Public health warnings are in effect, with health systems seeing increased admissions and sadly, multiple fatalities linked to the heat. Schools have closed in France, and attractions like the Eiffel Tower and Brussels’ Atomium shut down early. Travel is disrupted by power failures and, in one case, storm damage linked to extreme weather. Wildfires are raging across southern Europe, forcing thousands of evacuations. Outdoor work is being restricted in several countries like Italy.
Is this intense heatwave linked to climate change?
Yes, scientists and international bodies like the WMO are strongly linking this intense heatwave to human-caused climate change. They state that while heatwaves are natural phenomena, climate change makes them more frequent, more intense, and longer-lasting. Rising global temperatures, amplified by phenomena like warmer sea temperatures, make extreme heat events like this significantly more likely than they would be in a climate unaffected by human activity. This heatwave is seen as part of a worrying trend towards a ‘new normal’ of extreme temperatures.
In summary, the severe heatwave gripping Europe and the UK is a significant event, marked by record-breaking temperatures, widespread disruption to daily life, and serious health and environmental impacts. Experts are clear that such extreme events are becoming more common and intense due to climate change, underscoring the urgent need for adaptation strategies and continued efforts to mitigate global warming.
