How often is this page updated?
Current conditions refresh daily at 07:00 UTC from our cron. Forecasts cache for 6 hours; climate averages for 24 hours; the 20-year historical distribution refreshes weekly.
What does the conditions score mean for Rock Werchter?
A single 0-10 rating of how Rock Werchter's event window is shaping up, weighted toward the festival's primary risk (wet and muddy ground conditions). Above 7 means likely good, 4-6 is mixed, below 4 means prepare for the worst.
Where does the weather data come from?
Open-Meteo, an open weather API that blends multiple national weather services plus ERA5 archive data going back to 2006. The same data powers many outdoor apps.
Does the historical comparison mean the festival ran every year?
No. The 20-year comparison uses weather records for this location and event window regardless of whether the festival itself ran that year. That gives us a consistent 20-year sample even for festivals that started more recently.
What should I pack for Rock Werchter 2026?
See the "Pack for it" section above. The list is generated from the current forecast, tuned to the temperatures, rain probability, and primary risk you will actually face.
