September trade-offs

  • Still 33°C and humid — not yet comfortable enough for extended outdoor exploration at midday
  • ACL Festival preparation drives accommodation booking rush; book October far in advance
  • September thunderstorms can be intense: 80mm with heavy concentrated bursts

October trade-offs

  • The most expensive month by a distance: hotels triple or quadruple for ACL and F1 weekends
  • Zilker Park and South Congress flooded with 450,000+ ACL attendees across the two weekends
  • Book rooms 6–12 months in advance for October — last-minute availability essentially zero
