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 campsite at 4am.
- 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 and mud 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.
- Wellies or waterproof boots, plus dry shoes for the good spells.
- A real rain jacket and a cheap poncho — the poncho covers your bag in a crowd.
- A tarp under the tent and pegs that hold in soft ground.
- Dry bags for phone, power bank and one sealed set of dry clothes.
Sleeping and night layers
Overnight lows average 20°C, with the coldest festival night typically near 19°C (Fri 31 Jul). A 1-season bag or even a duvet-style liner is enough — most nights you'll sleep on top of it, not in it.
- An insulated mat — the ground takes more heat than the air.
- 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.
