June trade-offs

  • Prices surging: hotels at 50–70% above winter rates and accommodation needs early booking
  • Charles Bridge and Old Town Square crowded all day; the Astronomical Clock viewing platform now has queues
  • 73mm rain — primarily afternoon thunderstorms; mornings are reliable but carry a poncho for afternoons

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
