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 26°C, so heat is rarely the main problem — but the warmest day still reaches about 28°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 100% of Lollapalooza days, averaging 2.0mm a day and about 8.1mm 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 20°C, with the coldest festival night typically near 19°C (Fri 31 Jul). 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 Lollapalooza site matters
Heat and humidity are exhausting in a downtown park with limited shade — water stations and the lakefront breeze are heavily used. Severe storms are the real disruptor: Lollapalooza has been briefly evacuated multiple times when lightning approached the city, and organisers monitor radar all weekend.
