PeakWave modelled guidance
Calculated from the event-window weather inputs and independent of the quality score. This is not an official alert.
Red guidance applies alongside the quality label “Mixed, long festival means streaks of both”. Red guidance means the lived conditions may still be severe. The quality label does not mean these conditions are safe or manageable.

Frequently asked questions
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 Roskilde?
A single 0-100 rating of how Roskilde's event window is shaping up. Rain or dust and ground, temperature, atmosphere and wind contribute as four equal factor groups. Their multipliers are multiplied into one event-window quality score. The festival's primary risk selects the first group's rain-and-ground or dust-and-ground interpretation and shapes the label and historical comparison. It does not give any group extra weight.
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 Roskilde 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.
