What to wear to Pentaport Rock Festival: Incheon sits at 30°C (86°F) by day and 24°C (75°F) at night in August, on open field, with a high chance of rain. That means loose natural fabrics and real sun protection, waterproof boots, and a bag small enough for the gate rules. The crowd leans rock, streetwear and camping, so anything that survives the day reads as right.
| Typical daytime high | 30°C (86°F) |
|---|---|
| Typical night low | 24°C (75°F) |
| Day–night swing | 6°C (11°F) |
| Rain risk | High |
| Ground | Grass that turns to mud |
| Sun exposure | High during the day, no shade at the main stages |
At 30°C (86°F), synthetic fabrics stop breathing and anything tight becomes uncomfortable within an hour. Cotton, linen and loose cuts outperform whatever looks best in a photo, and SPF is part of the outfit, not an extra.
Assume rain. A packable shell in your bag costs nothing to carry and saves the weekend; a "cute" jacket that soaks through ruins two days.
Everything below follows from those numbers.
