A three-day pass to Iowa’s Hinterland Music Festival buys a weekend of music, but its heat policy treats each day separately. The Nov. 13 presale was scheduled to open at 11 a.m. Central for the July 30–Aug. 1, 2027, festival in St. Charles. The published lineup puts Slayyyter on Friday, Phoebe Bridgers on Saturday and Billy Strings on Sunday.
The festival’s 90 Degree Guarantee uses the Weather.gov forecast for ZIP code 50240 at 10 a.m. Central on Monday, July 26. If the forecast puts any festival day at 90°F or higher, buyers with eligible admission tickets can request a refund for that day. The rule uses the forecast temperature, so a hot day at the festival is not itself a trigger.
Say the forecast hits 90°F on Saturday alone. A buyer with an eligible three-day pass could request one-third of its price back for Saturday. If two days qualify, the same math comes to two-thirds. The policy applies to admission only; it excludes camping, parking and shuttle passes even if a buyer no longer needs them.
The organizer lists two eligible purchase routes: direct through Front Gate Tickets or through AXS during the early bird presale. Third-party resale is excluded. The general ticket policy says the festival goes ahead rain or shine and lists the heat guarantee as its exception to the no-refund, no-exchange rule.
Under the published timetable, the request form opens at the July 26 forecast check. Buyers must submit it before 5 p.m. Central on Tuesday, July 27, and the festival says it will process eligible returns in about 14 days. That gives buyers a deadline before the first set: check the Monday forecast and decide by Tuesday whether to claim a refund for a qualifying day.
