What rain actually does to Copenhell
Refshaleøen is concrete, gravel and steel — drainage is excellent, so the site never turns to mud, but wind off the harbour makes cool days feel raw. On the rare hot afternoon the lack of shade and the dark clothing of the crowd push everyone toward the bar tents and the harbour swim spot.
If the forecast turns wet
- Boots over trainers, and a spare pair of shoes sealed in a bag.
- Rain jacket for walking, poncho for standing in a crowd with a backpack.
- Pitch on the high side of the field, never in a dip, and use a groundsheet.
- Dry bags for phone, power bank, tickets and one full change of clothes.
How we know
These numbers come from the Open-Meteo historical reanalysis at the festival's coordinates, averaged day by day over about 15 years. They describe a typical edition, not the one you're going to — for the live picture, the Copenhell forecast page updates twice a day once the event is inside the forecast window.
