Europe Heatwave 2026: Over 95 Million People Face Extreme Temperatures Exceeding 35°C

Historic Early-Summer Heatwave Scorches Europe, Affecting Over 95 Million People

An unprecedented and severe heatwave has swept across Europe at the very start of the summer season, leaving more than 95 million people exposed to blistering temperatures exceeding 35°C (95°F).

According to a statistical analysis conducted by Agence France-Presse (AFP), while the extreme weather has begun losing some momentum compared to the previous day—where an estimated 130 million people experienced temperatures above 35°C—the scale of the impact remains staggering. Currently, roughly two out of every five individuals across the continent (excluding Turkey) are battling conditions hovering above 30°C.

Climate Experts Call Heatwave "Virtually Impossible" Without Global Warming

Such high temperatures so early in the season are highly unusual for Europe. The prolonged thermal stress has already caused significant disruption, leading to spikes in excess mortality, temporary school closures, and the widespread cancellation of outdoor public events.

Scientists from the World Weather Attribution group noted that an intense heatwave of this magnitude in June would be "virtually impossible" to occur without the driving forces of human-induced climate change. The World Health Organization (WHO) has reminded public sectors that Europe remains the fastest-warming continent on Earth, heating at twice the global average.

Eastern and Southern Europe Hit Hardest

The core of the extreme heat has gradually shifted toward the eastern and southern regions of the continent. The following table highlights the severe structural and regional impact recorded during this historic event:

Country / Region	Peak Temperature / Impact	Notable Context
Hungary	41.8°C to 42.0°C	Almost the entire population faced temperatures above 35°C; set a new all-time national record.
Czechia	41.9°C (Doksany)	Smashed the previous historical national record by an unprecedented 1.5°C.
Slovakia	41.0°C	Logged historical temperature highs, causing major disruptions.
Ukraine	35°C to 38°C	Enforced emergency power grid outages due to high consumption and heat strain.
Italy & Balkans	Multiple Red Warnings	22 Italian cities placed on maximum heat alerts; active wildfires reported in Croatia and Albania.

Data Underestimates Urban Realities

The projections were calculated by combining weather forecasts from Germany’s national weather service, the Deutscher Wetterdienst (DWD), with population density datasets from the European Joint Research Centre.

However, experts from the Austrian environmental organization Klimadashboard warned that these figures likely underestimate the true human impact. The automated models do not fully account for the "urban heat island effect," a phenomenon where concrete structures, asphalt roads, and a lack of open green spaces cause cities to traps heat, making urban centers significantly hotter than surrounding rural environments.
