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 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 and mud kit — don't skip this
Rain falls on roughly 83% of Tomorrowland days, averaging 2.0mm a day and about 12.1mm 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 15°C, with the coldest festival night typically near 15°C (Sat 18 Jul). A 2-season bag with a comfort rating around 8°C covers these nights comfortably.
- An insulated mat — the ground takes more heat than the air.
- A hoodie you don't mind losing.
Why the Tomorrowland site matters
The site has good drainage and a lot of trees, so rain rarely ruins the festival outright, but heavy thunderstorms have forced temporary stage evacuations in past years. Heat is more of an issue inside the densely packed main-stage crowd than out in the woods. A light poncho is the standard insurance policy.
