France is grappling with an intensifying heatwave that has triggered orange-level weather alerts across a quarter of the country, including Paris. According to the national meteorological service, temperatures are forecast to climb toward 40°C (104°F) as climate change drives more frequent and severe heat events. The surge has already forced school closures and the cancellation of 71 long-distance train services to prevent air conditioning failures, officials report.
Why are French schools and transport systems struggling?
Infrastructure in France is increasingly failing to cope with extreme heat, particularly in buildings not designed for high temperatures. According to reports from academic institutions and unions, many school facilities lack the cooling systems necessary for 40°C weather. In Tours, Mayor Emmanuel Denis has stated he will shutter 58 schools if thermometers reach the 40-degree threshold. This follows a precedent from last June, when approximately 2,200 schools were forced to close due to similar conditions. Meanwhile, the state rail operator SNCF canceled 71 long-distance trains between Thursday and Monday to avoid technical malfunctions linked to heat-stressed cooling systems.
In an effort to provide relief during the heatwave, officials in eastern Paris have opened the Saint-Martin Canal for supervised public swimming since Wednesday.
How are climate trends changing European summers?
Scientists and meteorologists agree that the frequency and intensity of heatwaves in Europe are rising, a direct consequence of climate change. French meteorologists note that the country is experiencing its second heatwave of the year before the astronomical start of summer. This follows an unusually hot May, which saw temperature records broken in half of the country. Unlike historical weather patterns, these heat events are now arriving earlier in the season and lingering for longer durations. The summer solstice, which marks the longest day of the year, is expected to further exacerbate the heating effect by increasing the total number of sunlit hours.
How do heatwave responses compare to previous years?
The current government response reflects a growing institutional urgency compared to past years. While local mayors previously reacted on an ad-hoc basis, there is now a more systematic approach to school scheduling and public warnings.
| Event | Scale/Impact |
|---|---|
| June 2023 Heatwave | 2,200 schools closed |
| June 2024 (Current) | Targeted closures and 71 train cancellations |
The shift from reactive closures to preemptive transport cancellations—such as the SNCF’s decision to pull trains before failures occur—highlights a shift toward risk mitigation in public infrastructure management.
Frequently Asked Questions
What is an orange weather alert in France?
An orange alert is the second-highest level of warning issued by the national meteorological service, indicating that citizens should exercise extreme caution and maintain high levels of hydration.

Are all schools in France closing?
No. School closures are decided on a local level. In Paris, for example, about ten high schools have already adjusted their schedules, but decisions are made based on specific building conditions and local temperature forecasts.
Why are trains being canceled if the tracks aren’t damaged?
According to the SNCF, the cancellations are primarily to “prevent potential air conditioning problems” caused by the extreme heat, rather than just physical track integrity.
Check your local municipality’s official website or the national meteorological service portal for real-time updates on school closures and public cooling center locations if you are traveling in France.
