France records 44.3C as heatwave strains services in Europe

A record-setting heatwave across Western Europe disrupted power, transport and schools as officials issued health alerts and reported dozens of deaths.

The extreme temperatures affected multiple countries on Wednesday, with authorities responding to outages, issuing high-level public health warnings and adjusting daily routines to reduce exposure. The impacts ranged from slowed rail services to farmers shifting harvest work into cooler overnight hours.

France faces record heat and infrastructure strain

France endured its hottest day since national records began nearly 80 years ago, with temperatures reaching 44.3C in the southwestern town of Pissos. The heat pushed emergency services and utilities into response mode, as demand and system stress coincided.

In Brittany, in northwestern France, officials worked to restore electricity after power cuts left thousands of homes without supply. The outages added to broader disruptions linked to intense heat, which can strain grids as cooling use rises and equipment operates outside normal tolerances.

Authorities also reported a heavy human toll tied to attempts to escape the heat. At least 48 people in France died by drowning while seeking relief in water, and two young children were reported to have died after being left in a car during the heat.

Italy and Britain escalate warnings as daily life shifts

Italy’s health ministry issued its top-level heat alert for 16 cities, including Florence, Milan, Rome, Turin and Verona. Such alerts typically signal conditions that can pose risks beyond vulnerable groups, prompting guidance on limiting outdoor activity and monitoring symptoms.

In Britain, temperatures were on track to make it the hottest June day on record. The Met Office issued an extreme-heat warning—only the second time it has used that highest category—citing the potential for impacts even among healthy people.

Education and transport were among the most visible pressure points. Hundreds of schools in Britain remained closed or ended the day early, while parts of the region reported slowed train services as rail operators manage safety risks linked to high track temperatures.

Spain reports heat deaths as temperatures begin to ease

Spain, which has faced extreme heat since the weekend with temperatures above 40C, reported two deaths from heatstroke among elderly people. By Wednesday, conditions were beginning to moderate in some areas, though officials continued monitoring for residual health impacts.

The week’s events underline how heatwaves can create cascading risks across sectors—healthcare demand rises, power systems and transport networks face operational constraints, and outdoor work becomes more hazardous. The pattern also shows how secondary dangers, such as drowning during heat relief attempts, can drive fatalities.

Emergency agencies across the region have urged residents to seek shade, stay hydrated, check on older relatives and neighbors, and avoid leaving children or animals in vehicles. Utilities and local authorities are expected to continue restoration work where outages persist, while health services track heat-related illness as temperatures fluctuate.

Next steps will hinge on how quickly temperatures fall and whether additional hot spells develop, with public alerts and service adjustments likely to remain in place until conditions stabilize.
