What to wear to Summerfest: Milwaukee sits at 27°C (81°F) by day and 17°C (63°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 rock, pop and americana, so anything that survives the day reads as right.
