May is high for Cesky Krumlov.

The catch is that crowds and prices climb sharply as the high season opens; midday day-tripper buses from Prague fill the narrow lanes from late morning to mid-afternoon. The fix is the standard one here: stay overnight and walk the Old Town at dawn or after dusk when the crowds clear.

Cesky Krumlov in May — Full Picture
May is one of the best months — about 19°C/8°C, comfortable for cobblestone walking, with the castle, Baroque Theatre, and Vltava rafting all in full swing. Greenery along the river peaks and the town looks its lushest.
The catch is that crowds and prices climb sharply as the high season opens; midday day-tripper buses from Prague fill the narrow lanes from late morning to mid-afternoon. The fix is the standard one here: stay overnight and walk the Old Town at dawn or after dusk when the crowds clear.
Rainfall rises notably (around 75mm) versus the dry winter, so pack a rain layer even on sunny forecasts. Riverside terraces and beer gardens are open, and rafting from Vyšší Brod down toward town is a highlight once the river warms.
May balances good weather, fully open sights, and slightly-less-than-peak crowds — a strong choice if you book accommodation early.
What to Wear & What to Pack
Mild and pleasant — about 19°C/8°C, ideal for walking, though rainfall climbs. Light layers, a t-shirt with a light jacket, and a packable rain layer. Comfortable shoes for cobblestones.
