Authorities have not specified the exact temperature threshold triggering the closures, but the decision impacts a significant number of educational facilities across the country. This action follows warnings from meteorological services about sustained high temperatures expected throughout the region. The closures are expected to affect primary and secondary school students, with potential disruptions to learning schedules. Officials are advising citizens to take necessary precautions against the heat, including staying hydrated and avoiding strenuous activity during peak hours. This is not the first time France has closed schools due to extreme weather events, reflecting increasing concerns about the impact of climate change.
