Europe is facing one of the most intense heatwaves in decades. In recent days, temperatures have climbed to levels considered exceptional even for the Mediterranean basin, turning many European cities into furnaces. The obvious question is now circulating everywhere: are we witnessing the hottest summer ever recorded?
According to Copernicus, the World Meteorological Organization and several national weather agencies, June 2026 is ending with thermal anomalies of more than +6°C above historical averages in parts of southern and central Europe. The main cause is a persistent African high-pressure dome, fueled by increasingly extreme Saharan air masses. What makes this event particularly alarming is its duration: this is not a short spike, but a long sequence of consecutive days above seasonal norms, dramatically increasing health and economic risks.

The hottest cities: where temperatures hit extreme levels
The geography of this heatwave shows that almost the entire continent has been affected. Several cities have already approached or broken historical records. Here are some of the highest temperatures recorded in recent weeks:
- Seville (Spain): 45.1°C
- Cordoba (Spain): 44.7°C
- Rome (Italy): 41.8°C
- Florence (Italy): 41.2°C
- Milan (Italy): 39.6°C
- Marseille (France): 42.4°C
- Paris (France): 39.8°C
- Lyon (France): 41.1°C
- Athens (Greece): 43.3°C
- Belgrade (Serbia): 40.5°C
- Budapest (Hungary): 39.4°C
- Vienna (Austria): 38.8°C
The most surprising trend is in Northern Europe: cities like Berlin, Prague and Warsaw have exceeded 35°C, a threshold once considered rare.
The death toll is rising
Heatwaves are among the deadliest climate events, but calculating casualties in real time is always difficult because many deaths are indirect. Early estimates suggest:
- France: more than 230 suspected heat-related deaths
- Italy: at least 190 monitored cases
- Spain: over 280 premature deaths
- Greece: dozens of serious hospitalizations
- Portugal: a sharp rise in elderly mortality
The most vulnerable groups remain:
- people over 75
- chronic patients
- agricultural workers
- outdoor laborers
- young children
The biggest issue is not just peak daytime heat, but tropical nights, with minimum temperatures above 28°C, preventing the human body from recovering.
Agriculture and farming are paying the highest price
If heat puts pressure on people, it creates a direct economic shock for businesses. European agriculture remains one of the sectors most exposed. The main problems include:
- early harvests
- lower cereal yields
- water stress in vineyards
- livestock mortality
- declining milk production
In Italy, Coldiretti says losses have already exceeded 15% in some crops. In France, wheat production may fall by 12%, while Spain fears an expansion of drought across olive-growing regions. Livestock farming is also under severe strain: above 38°C, cattle and pigs reduce food intake and productivity.
Energy, tourism and work: everything changes
It is not only farming that suffers. Record heat is reshaping entire economic sectors. Industries under pressure:
- energy, due to soaring electricity demand
- urban tourism, with fewer daytime visitors
- construction and logistics, slowed by safety concerns
- rail transport, disrupted by track expansion from heat
In Italy and France, electricity consumption for air conditioning has already hit seasonal highs, pushing spot-market energy prices upward again.
Will July be even worse?
July may prove even more critical. According to ECMWF and Meteo France, the African high-pressure system is expected to remain dominant for at least the first half of the month. Forecasts indicate:
- temperatures 4-7°C above average
- possible new peaks above 44°C
- higher wildfire risks across the Mediterranean
- potential localized blackouts
- increasing water shortages
The biggest unknown remains persistence. If the heat continues without interruption, 2026 could enter the history books as one of the most extreme summers Europe has ever experienced. And perhaps the most unsettling fact is this: what seemed exceptional just a few years ago is starting to look like the new normal.
