What to wear to Lollapalooza Brasil: São Paulo sits at 27°C (81°F) by day and 19°C (66°F) at night in March, on arena grounds, with a high 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 y2k, streetwear and pop, so anything that survives the day reads as right.
| Typical daytime high | 27°C (81°F) |
|---|---|
| Typical night low | 19°C (66°F) |
| Day–night swing | 8°C (14°F) |
| Rain risk | High |
| Ground | Concrete and gravel |
| Sun exposure | High, little natural shade |
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.
