  • Prague Castle lit after dark in December: the hilltop complex above the Vltava at its most fairy-tale atmospheric — visit at dusk for the full effect
Prague May — green riverside park with Prague Castle across the Vltava in late spring light

December trade-offs

  • Cold: -1°C overnight requires proper winter clothing for any evening market visit
  • Christmas market premium: accommodation rates 30–50% above November across the city
  • New Year's Eve crowds: the 31st is extremely busy in the centre — plan your location in advance

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
