Western Europe faced another intense heat wave on Thursday, with the UK registering its highest temperature of the year and provisional temperatures in France surpassing 42°C. These repeated extremes are putting pressure on hospitals, workplaces, water supplies, and emergency services, making heat adaptation a critical safety requirement.
The temperature in west London reached 38.1°C on 13 August, just slightly higher than the previous 2026 high of 38°C recorded in June, according to the Met Office. This was below the British August record of 38.5°C set in 2003 and occurred during the country’s fifth heatwave of the year.
In France, conditions were even more severe. Météo-France reported a provisional temperature of 42.5°C at Châteaumeillant in the Cher department at 17:00 local time, which would be an August record for that station if confirmed. Other locations, such as Saint-Laurent-du-Pape, Joué-lès-Tours, and Bordeaux, also recorded extremely high temperatures.
The national weather service declared Thursday as the peak of the heatwave in France, the third of the summer, which began on 28 July and persisted as temperatures in the southeast remained high.
Relief was expected along the Channel and Atlantic coasts on Friday, gradually moving eastward during the weekend, although eastern France was forecasted to remain hot, possibly experiencing thunderstorms.
Warm nights compounded the situation, with parts of western France seeing record-high minimum temperatures. Persistently warm nights hinder recovery from daytime heat, posing risks, especially to vulnerable groups like the elderly, infants, and those with health issues.
These heat events are highlighting gaps in workplace safety measures, as workers cannot always avoid exertion or stay indoors. Employers need effective plans, such as allowing rest periods and providing drinking water and shaded areas.
Warnings also need to be accessible to migrants, tourists, homeless individuals, and those without digital access, as information may not reach everyone at risk.
Drought conditions in France, with record soil dryness, are increasing wildfire risk and putting pressure on water resources. Britain is facing similar dry conditions, impacting fire management. These issues demonstrate the interconnectedness of heat, drought, and fire as emergencies.
Adaptation efforts must prioritize protecting those with limited options, as wealthy households have more means to adapt. Repeated heatwaves call for more than just emergency advice; enforceable workplace protections, accessible cooling spaces, and community-level plans are essential.
As temperatures eventually fall, the root causes of exposure remain. Western Europe’s heat emergencies underline the urgency of climate adaptation as a current necessity to safeguard health, dignity, and working conditions.
