Is It Cold at Night at Sziget Festival?

Overnight lows average 18°C across the main days, based on roughly 15 years of records at the site.

The short answer

Not really — Sziget nights stay mild, averaging 18°C, with the coolest festival night near 17°C (Wed 12 Aug). A light layer is usually enough after dark.

A 1-season bag or even a duvet-style liner is enough — most nights you'll sleep on top of it, not in it.

Long-run averages, not a forecast. Individual years swing several degrees either side.

Sleeping warm in a tent

  • Insulate underneath first. A cheap foam mat under an air mattress does more than a warmer bag.
  • Dry clothes to sleep in. Damp festival clothes will keep you cold all night.
  • A beanie and dedicated sleep socks — the cheapest comfort upgrade in the bag.
  • Eat something before bed and don't go to sleep dehydrated; both make you feel the cold more.

Why nights matter to the weather score

Our festival weather score treats overnight lows separately from daytime highs, because a warm afternoon doesn't make up for a night you can't sleep through. Nights between roughly 10 and 24°C count as comfortable camping weather; below that the score starts to drop, and it drops sharply once lows fall under about 8°C.
