What's the weather like in Český Krumlov by month?
Each month classified as peak (best balance of weather and value), shoulder (a step in either direction), or low season.
Why visit Český Krumlov during May–Jun, Sep–Oct?
A genuinely good window — temperatures climb steadily through the period, the gardens come alive with blooms, the rafting season begins in May, and crowds remain manageable until the late-May Five-Petalled Rose Festival. Some rain; pack a light waterproof.
Shoulder season (Apr, Jul–Aug, Nov) trades a small weather concession for noticeably smaller crowds and softer prices — often the sweet spot for travelers who want flexibility.
Low season (Jan–Mar, Dec) is when prices fall hardest. Expect weather extremes (heat, humidity, cold, or rain depending on the destination) and reduced hours at some seasonal businesses, but the trade-off can be worth it if budget or solitude matters more than perfect conditions.
What festivals and events happen in Český Krumlov?
- Five-Petalled Rose Festival (Slavnosti pětilisté růže)Late June
The town's biggest annual event — a three-day medieval re-enactment festival commemorating the Rožmberk family (whose coat of arms featured a five-petalled rose). Costumed processions, jousting, medieval markets, and an evening fire show on the Vltava. Hotel rates spike for this weekend; book 3–4 months ahead.
- Open-Air Revolving Theatre (Otáčivé hlediště)June – September
One of only a handful of revolving open-air theatres in the world — the audience seating slowly rotates 360° during performances in the Castle Gardens. Czech-language theatre, opera, and ballet; English subtitles available for major performances. 350–800 CZK ($15–$35) per show; book ahead.

- Christmas MarketsLate November – December
Wooden stalls fill the central Náměstí Svornosti — mulled wine (svařák), trdelník chimney cakes, hand-carved wooden ornaments, sausages. Smaller and more intimate than Prague's; the snow-on-cobblestones atmosphere is magical. Saturday markets are busiest.
- St. Wenceslas DaySeptember 28
Czech national holiday — Český Krumlov hosts a small parade and a free open-air concert in the central square. Most museums offer reduced admission; many shops close.
