Quick summary
- Western Europe is facing unusually early heat linked to a heat dome.
- Parts of the UK and France reported record May temperatures, while Spain and Italy faced heat risks.
- Health risks can rise when overnight temperatures stay high and people get less recovery time.
Western Europe is facing an unusually early spell of extreme heat, with record May temperatures reported in parts of the United Kingdom and France and alerts spreading across the region.
Agence France-Presse reported that the hot spell is being driven by a "heat dome", where warm air from northern Africa is trapped under a high-pressure system over western Europe. The pattern has pushed temperatures to levels more commonly associated with high summer.
France recorded its hottest May day on Monday and again on Tuesday, according to reports citing the national weather agency. The United Kingdom also recorded unprecedented May highs, while Spain was expected to see temperatures rising toward 38C in some areas.
Why it matters
The timing is important. Early-season heat can be harder on people because homes, workplaces and public services may not yet be prepared for summer-level temperatures. It also increases pressure on outdoor workers, older people and those with health conditions.
Parts of Italy have already imposed restrictions on outdoor work during the hottest hours, while French authorities have placed several areas under heat alerts as the episode continues.
What happens next
Forecasters expect the heat to remain a concern through the week in parts of western and southern Europe. If overnight temperatures stay high, health risks can rise because the body gets less time to recover from daytime heat.
The episode is also likely to renew debate over how European cities adapt to earlier and more intense heatwaves, from public cooling plans to protections for outdoor workers.

Why it matters
Early heatwaves strain health systems, outdoor workers and cities before summer preparedness is fully in place.
