What rain actually does to Sónar
Most of Sónar happens indoors or under cover, so the weather affects the journey more than the music. The heat does push the daytime programme toward shaded courtyards and air-conditioned halls, and by Sónar by Night the cooler air of the Fira venue is part of the appeal.
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 Sónar forecast page updates twice a day once the event is inside the forecast window.
