Rock en Seine 2025: what weather forecast for the five days of the festival?

The 2025 edition of Rock en Seine officially opens its doors this Wednesday, August 20 at the Domaine National de Saint-Cloud ( Hauts-de-Seine ). After Billie Eilish in 2023, then Lana Del Rey last year, it's the turn of the young artist Chappell Roan to open the ball. The following days will see performances by Kid Cudi, replacing ASAP Rocky , Justice and Last Train. But festival-goers are especially worried about the weather forecast for the next few days.

The opening day promises to be rainy. The festivities, which begin at 5 p.m., will be marked by light rain, according to Météo France. Chappell Roan, scheduled for 9:45 p.m., will also sing in the rain. Temperatures will range between 17 and 19 degrees.

The next day will be clearer. Festival-goers can expect sunny and partly cloudy weather, with an afternoon temperature of 21 degrees Celsius (70 degrees Fahrenheit). The night will be cooler, with a forecast of 17 degrees Celsius (65 degrees Fahrenheit).

For Friday's performances, including DJ Anyma 's (at 10:45 p.m.), the weather is expected to remain pleasant. Sunny spells are forecast for the day, with relatively cool temperatures, however, ranging between 17 degrees and 15 degrees in the evening.

Saturday, August 23, is also expected to offer participants a storm-free day. The mercury is expected to reach 19 degrees during the day and 15 degrees in the early evening.

Clear skies are expected for the festival's closing day. With temperatures of 20 degrees Celsius in the afternoon and 16 degrees Celsius in the evening, we recommend bringing a light sweater to fully enjoy the final shows until 11:20 p.m.
