France Hit by Unusually Early Heat Dome With 18 Departments on Alert

Overview

• Météo‑France extended its heat vigilance to 18 departments on Monday, with eight western departments raised to orange for Tuesday as daytime highs reach the low‑ to mid‑30s.
• Emergency services reported several people hospitalized at weekend sporting events and at least one death linked to a running race in Paris, prompting public‑safety advisories.
• Meteorologists say a persistent 'dôme de chaleur' is funneling hot air across the Iberian Peninsula and holding it over France under a strong anticyclone, causing nights to stay unusually warm in coastal areas.
• Hundreds of provisional May temperature records have fallen across the west and south‑west, including night‑time 'tropical' lows above 20°C in stations such as Lorient and Nantes.
• Scientists and authorities warn the event matches climate change trends, raise the risk of ozone pollution and strains on emergency services, and say officials will monitor the situation ahead of a planned government review later this week.
