Six Sex takes over Outset in Chicago on July 31 for the Official Lollapalooza Aftershow, and the outdoor setting means the sky is as much a part of the night as the setlist. Doors are worth planning around, since this is a 22:00 CT (10 PM) show and Outset is fully outdoor — weather is part of the experience here, not a backdrop.
What the Weather Looks Like
The National Weather Service’s Friday forecast for the area calls for a high near 84°F, mostly sunny skies, and a slight chance of showers and thunderstorms with a 23% probability of precipitation. Wind stays light out of the SSE at 5 mph. That forecast covers the daytime hours, but it’s the best data available for planning the day — expect it to feel noticeably cooler once the sun goes down for the 22:00 set, even though an exact evening number isn’t in the forecast.
Bottom line: it’s a warm, mostly sunny Chicago day with only a slight chance of a pop-up storm. Dress light for the walk in, but don’t rule out a passing shower.
What to Wear and Bring
If you’re heading to Outset earlier in the day to soak up the Lollapalooza atmosphere before the aftershow, sun protection matters more than rain gear. Pack the SPF 50 sport sunscreen so you’re covered through the mostly sunny afternoon, and reach for comfortable walking sandals — you’ll be on your feet for hours between the fest and the aftershow.
With a 23% chance of showers and thunderstorms in the mix, it’s worth having a packable rain jacket stashed in your bag just in case a storm rolls through. It packs small enough that you won’t notice it until you actually need it.
Festival Gear That Actually Helps
A hydration backpack is the single most useful thing you can bring to an outdoor festival day that stretches from daytime heat into a late-night set — hands-free water beats standing in line at a concession stand between acts. Pair it with a portable phone charger 20000mah so your phone survives photos, texts with your group, and rideshare coordination well past midnight.
For the aftershow itself, a clear stadium bag is your safest bet for getting through security without hassle at most outdoor venues — check Outset’s bag policy ahead of time, but clear bags are the standard that gets waved through fastest.
Getting In and Getting Around
Give yourself extra time getting to Outset on a night like this — Lollapalooza aftershows draw heavy crowds right as the main festival lets out, so parking and rideshare pickup zones fill up fast. Arrive early, bring a valid ID, and check what Outset allows for outside items before you pack your bag.
The Move for the Night
With temps near 84°F during the day cooling toward evening and only a slight chance of storms, this is a night to dress light, stay hydrated, and keep a rain jacket within reach just in case. Rep your fandom, keep the hydration backpack on, and let Six Sex do the rest.
