What to wear to Montreux Jazz Festival: Montreux sits at 25°C (77°F) by day and 15°C (59°F) at night in July, 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 jazz, elegant and wine, so anything that survives the day reads as right.
