What to wear to Wonderfruit: Pattaya sits at 32°C (90°F) by day and 22°C (72°F) at night in December, on open field, with a low chance of rain. That means loose natural fabrics and real sun protection, broken-in boots or sturdy trainers, and a bag small enough for the gate rules. The crowd leans boho, costume and psy, so a full costume is the norm rather than the exception.
| Typical daytime high | 32°C (90°F) |
|---|---|
| Typical night low | 22°C (72°F) |
| Day–night swing | 10°C (18°F) |
| Rain risk | Low |
| Ground | Grass that turns to mud |
| Sun exposure | High during the day, no shade at the main stages |
At 32°C (90°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.
Everything below follows from those numbers.
