What to wear to Glastonbury Festival: Pilton sits at 21°C (70°F) by day and 11°C (52°F) at night in June, on open field, with a high chance of rain. That means a light base with one warm layer you can carry, waterproof boots, and a bag small enough for the gate rules. The crowd leans grunge, boho and camping, so anything that survives the day reads as right.
| Typical daytime high | 21°C (70°F) |
|---|---|
| Typical night low | 11°C (52°F) |
| Day–night swing | 10°C (18°F) |
| Rain risk | High |
| Ground | Grass that turns to mud |
| Sun exposure | High during the day, no shade at the main stages |
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.
