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
- Waterproof shoes over trainers — you'll be on wet pavement and grass all day.
- Rain jacket for walking, poncho for standing in a crowd with a backpack.
- No campsite here, so the fix for a bad hour is indoors, under cover, or an early trip home and back.
- A dry bag for phone, power bank and tickets, and dry clothes waiting at home.
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.
