What to wear to Wireless Festival: London sits at 23°C (73°F) by day and 15°C (59°F) at night in July, on city park, 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, hip-hop and urban, so anything that survives the day reads as right.
| Typical daytime high | 23°C (73°F) |

| Typical night low | 15°C (59°F) |
| Day–night swing | 8°C (14°F) |

Everything below follows from those numbers.
