Lollapalooza
Weather & terrain
Chicago in late July runs hot and humid with a real chance of pop-up thunderstorms — the festival has weather-evacuated before. Concrete and turf underfoot all day.
The typical range
Expect days 82-92°F, humid at the hottest point and nights 65-72°F — that swing, not the average, is what your layers need to cover. The lake breeze shows up after sunset; a light layer in the bag covers the headliner and the walk to the train. Nothing heavy — you will carry it all day.
Build around conditions, not averages
Historical conditions help you choose categories, but a current forecast and official alerts should decide your final layer, rain, dust, and heat plan.
A simple final check
Seven days out, recheck the forecast, event communications, travel route, and your official rules source. Repack only what those current conditions change.
