Always in the bag
- Refillable water bottle — sealed or empty so it gets through the gate.
- Sunscreen SPF 50 — even a cloudy festival day is six hours outdoors.
- Power bank — your phone is your ticket, your map and your group chat.
- Earplugs — for the front rail, and for the ride home afterwards.
- More socks than days.
Sun and heat
Highs average 25°C, so heat is rarely the main problem — but the warmest day still reaches about 26°C and shade is limited at most sites.
- A wide-brim hat and sunglasses beat a cap for full-day sets.
- Loose, light-coloured long sleeves cover more skin and feel cooler than a vest.
Rain kit — don't skip this
Rain falls on roughly 67% of Sónar days, averaging 1.2mm a day and about 3.7mm across the main days.
- Waterproof shoes you can walk and dance in, and dry socks waiting at home.
- A real rain jacket and a cheap poncho — the poncho covers your bag in a crowd.
- A small folding bag for the wet layer once the shower passes.
- A dry bag or zip bag for phone, power bank and travel card.
Evening layers
Evening lows average 18°C, with the coldest festival night typically near 18°C (Fri 19 Jun). You won't need much after dark — a T-shirt and a light overshirt is plenty for the walk or ride home.
- A layer that packs down small enough to carry from doors open to last set.
- Comfortable shoes for the walk or the night bus home.
- A hoodie you don't mind losing.
Why the Sónar site matters
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.
