What should I pack for Austin?

Austin's summer heat catches first-timers harder than they expect. Mid-June daytime highs sit around 35-38°C, and humidity tends to hover near 78%. You'll feel it the moment you step outside Austin-Bergstrom International. Three or four moisture-wicking shirts will get you through a week if you rinse them in the hotel sink each night. Cotton feels fine in the AC and turns into a damp weight by the time you reach the Texas State Capitol, about a 15-minute walk from the Warehouse District. The UV index regularly hits 10-11 between May and September, so a wide-brim hat matters more than another pair of sunglasses. Shade along South Congress Avenue south of Oltorf Street is sparse, and the reflected heat off the pavement adds another 3-4°C to what your skin feels.

Swimwear goes in the carry-on, not the checked bag. Barton Springs Pool, the spring-fed swimming hole in Zilker Park, holds a constant 20°C year-round. The shock of that cold water after a 36°C afternoon is one of the best physical sensations Austin offers. Entry runs $5 for non-residents, $3 for Austin residents. A quick-dry travel towel saves you from hauling a soggy hotel towel around the Barton Creek Greenbelt afterward. Those trails stretch about 12 km and involve scrambling over exposed limestone, so closed-toe shoes with decent grip matter. Flip-flops work for 6th Street bars and South Congress shops, but they'll fail you on the Greenbelt within the first kilometer. If you're planning to swim at Hamilton Pool Preserve, about 37 km west of downtown, reservations fill up weeks ahead during summer. Check the Travis County Parks site before you go.

Austin's weather shifts fast between May and October. Afternoon thunderstorms tend to roll in with maybe 20 minutes of warning, dump hard rain for 30-45 minutes, then clear to blue sky. A packable rain shell that weighs under 200 grams saves you from getting soaked while waiting in the 2-3 hour weekend line outside Franklin Barbecue on East 11th Street. Evenings cool to about 24-26°C, which feels pleasant after 8 hours above 35°C. You won't need a jacket for outdoor stages at Stubb's Bar-B-Q on Red River Street or the Continental Club on South Congress. Mind you, restaurant AC in Texas runs cold. A long-sleeve layer for dinner at Uchi on South Lamar or Odd Duck keeps you from shivering through the tasting menu. That temperature gap between the sidewalk and the dining room is easily 15°C.

Skip packing sunscreen, bug spray, and basic toiletries. H-E-B, the Texas grocery chain with a cult following, sells most of it cheaper than whatever you'd pay at a CVS back home. A bottle of Banana Boat SPF 50 runs about $8 at the H-E-B on East 7th Street. Mosquito repellent matters for evening walks around Lady Bird Lake's 16-km hike-and-bike trail, and a can of OFF! Deep Woods goes for around $7. Worth noting, Austin is one of the most casual cities in the US. Nobody dresses up for dinner, even at higher-end spots like Emmer & Rye on Rainey Street. Clean shorts and a decent shirt will get you into any restaurant in town. The only place you might encounter a dress expectation is the Driskill Hotel bar on Brazos Street, and even there it's closer to 'no tank tops' than 'jacket required.'
