August trade-offs

  • Crowds unchanged from July: Old Town essentially a tourist theme park in August daytime hours
  • European school holidays: peak of family tourism, queues at Josefov, the castle, and the Old Town Hall tower
  • Prices remain at annual highs throughout — no relief from July rates until September

May trade-offs

  • Crowds building: Old Town noticeably busier than April, and Charles Bridge congested at midday
  • 72mm of rainfall — the greenest month is also the wettest; afternoon thunderstorms possible, carry a poncho
  • Book 4–6 weeks ahead; May is now the most in-demand shoulder month and fills fast
