France's summer of heatwaves left a mark on its festival circuit. A preliminary review of the 2026 season from the Centre national de la musique (CNM), presented on October 15, 2026 at the MaMA event in Paris, found that 91% of the music and comedy festivals that went ahead in 2026 ran into some or many difficulties, up 12 points from 2025, and that extreme heat has become the most common weather threat by far.
The numbers
The CNM's Bilan anticipé des festivals en 2026 covers 1,035 music and comedy festivals that planned a 2026 edition. Among those that ran, 43% said they faced many difficulties. Among festivals reporting difficulties, money was the top problem, cited by 71%, followed by natural hazards (55%), recruiting volunteers (35%) and clashing events (34%).
Of the 998 festivals that went ahead, 49% said they were hit by natural hazards, 13 points more than in 2025. Outdoor festivals were hit hardest: 67% of fully open-air events were affected, against 24% of fully indoor ones. Among the festivals reporting a hazard, 76% named extreme temperatures, a jump of 34 points from the year before. Storms (28%) and heavy rain (21%) followed.
Organizers are adapting. The report says 63% took at least one measure against weather risks, most often specific communications to fans and changes to the site such as cool zones and water fountains. Nearly a quarter (24%) turned to insurance against cancellation or bad weather, and 23% added emergency and first aid resources. For 22%, those plans were put in place only a few days before the event.
Solidays and the cancellations
According to franceinfo, the CNM tracked more than 40 full or partial festival cancellations over the summer, covering more than 60 performances that should have taken place between June and August. The most visible was Paris's Solidays, canceled hours before opening during a heatwave in late June. IQ Magazine notes that Solidays usually welcomes around 170,000 people over three days, and that Garorock in Marmande lost its opening day the same weekend.
Full fields, thin margins
Fans kept coming. The average fill rate reached 77%, and a third of festivals reported attendance at or above 90%. That did not translate into profits. The CNM says 35% of festivals reported a deficit, 46% broke even and only 19% made money, as roughly half saw higher artist and technical costs, especially for security, and a quarter paid more for insurance. More than eight in ten said their next edition will go ahead, but up to 17% of contemporary music festivals could not yet say so.
Independent organizers are sounding the alarm. Franceinfo reports that the Syndicat des musiques actuelles (SMA), which represents around 600 independent structures, said in French that “we are reaching a critical situation that is hitting festivals hard,” and that more than a third of its responding member festivals finished in the red, with an average deficit above €76,000.
France's Ministry of Culture says festivals get priority for weather vulnerability assessments under its ATLAS project, has asked the CNM to study insurance coverage for open-air music events, and will soon launch a mission, ahead of summer 2027, on shared criteria for deciding when festivals can go ahead. A full 2026 report, adding festivals held from September to December, is due in summer 2027.
