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
