If the weather is really bad, some performances might be cancelled or relocated to ensure the artists’ safety. These decisions are taken at this very moment together with the organisers and the artists depending on the evolution of the weather. This cannot be predicted. Information about possible changes is directly published on the website of the festival.
Even when it is raining, most of the stages and bleachers remain in open air; so don’t forget to get dressed and equipped accordingly.
NB: For the same security reasons, some performances may be cancelled due to other weather conditions (heat, wind gusts…)
