The weather

It's simple: pack a little of everything in your backpack.

Rain...

The weather here varies greatly from day to day, and can go from a very rainy day to a very hot one. If you're unlucky enough, you'll be delighted to have a k-way, although after a few dance steps you'll certainly be as wet inside as outside. The less prepared will be cutting holes in garbage bags - let's face it, there are better things to do :)

... to the sun at its zenith

When the days get really hot, Q-Dance provides several places for festival-goers to pick up some sun cream. But nothing beats your own. One of the great advantages of taking your own with you (apart from avoiding sunburn) is that you won't have to leave your favorite stage to apply it.

You should also take something to protect your head from sunstroke (cap, bob, cardboard hat or whatever), especially if you're bald. I say this in jest, but I can assure you that strawberry vanilla is a common color in the sun.

Hydrate yourself

To keep hydrated without breaking the bank on the festival grounds, I recommend you buy a water bottle in the festival colors. They cost 2 tokens, and you can fill them with drinking water just about anywhere. This will always be more cost-effective than paying 1 token for each bottle of water, especially useful if you plan to drink alcohol regularly.

And at night?

At night, temperatures are decent (or even slightly chilly for the more chilly), so take a sweatshirt or hoodie with you too if you're going to be out and about in the middle of the night, or if you've just had a cold shower. It would be a shame to catch a cold during the night.

Anticipate

As you can imagine, the weather is changeable and can take you by surprise. Don't be caught unprepared: anticipating is the key to a successful festival. The last piece of advice I can give you: find out what the weather's like before you go, and keep a close eye on how it's evolving. It won't cost you a thing, and will certainly save you a lot of trouble on site.
