What to wear to Osheaga: Montreal sits at 26°C (79°F) by day and 16°C (61°F) at night in August, 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 indie, streetwear and y2k, so anything that survives the day reads as right.
| Typical daytime high | 26°C (79°F) |
