Old Town in January

Late spring through early fall gives you the best weather and longest days. May and September hit the sweet spot — warm enough for outdoor dining, cool enough for comfortable walking, and fewer crowds than peak summer. Summer brings 16-hour days and packed squares. July temperatures reach 25°C regularly, perfect for evening strolls along the river. But you'll share those strolls with half of Europe. Winter has its own magic. Christmas markets fill the squares from late November through January, and snow on Gothic spires looks like a fairy tale. Just bundle up — temperatures drop to -5°C, and those stone streets turn icy.
