The best time to visit Olomouc

The best months for Olomouc are May–June and September — warm enough for the whole loop on foot, without the summer crowds on the Upper Square. The city is compact and most of the visit is outdoors, so the season mostly changes how pleasant the walk is — the sights themselves stay the same all year.

Month by month

If you only pick one month — May. Temperature is the mean over the whole day (not the daily high), and a rainy day has at least 1 mm of rain; averages for 2021–2024.

Spring and early autumn hold the temperature at a point where the whole loop — both squares, the climb to the cathedral, then back — can be walked in one go without a break for heat or cold. They're also the months with fewer visitors on the Upper Square, which offers little shade to wait in.

In summer the Upper Square is busiest just before noon, once the crowd gathers for the clock. The day's schedule itself doesn't change — the show is still only performance once daily, at noon — only how long you wait for a good spot does. Anyone who wants the square to themselves comes earlier and returns once the show ends and the crowd moves on.

The cathedral, museums and restaurants in the old core run through winter as usual. What changes is how long you stand outside — the squares offer no shelter, so lingering by the clock or the fountains calls for warmer clothes.

• Climbing the cathedral tower doesn't depend on the month. A slot is booked ahead, timed slot (for the tower), the same in summer and winter.
• The clock runs the same all year. The one show is performance once daily, at noon; no season adds a second.
