What to wear to I-Days: Milan sits at 29°C (84°F) by day and 19°C (66°F) at night in June, on city streets, with a moderate chance of rain. That means a light base with one warm layer you can carry, cushioned trainers or a low boot, and a bag small enough for the gate rules. The crowd leans streetwear, glam and y2k, so anything that survives the day reads as right.
| Typical daytime high | 29°C (84°F) |
|---|---|
| Typical night low | 19°C (66°F) |
| Day–night swing | 10°C (18°F) |
| Rain risk | Moderate |
| Ground | Tarmac and pavement |
| Sun exposure | High, little natural shade |
Everything below follows from those numbers.
