- May and early June offer the best balance: warm weather, flowers in bloom, and fewer crowds than July-August.
- July and August draw massive summer crowds; June and September are slightly less crowded alternatives with similar warmth.
- Winter (Nov-Feb) is least crowded outside Christmas period; dress warmly for temperatures around freezing or below, with short daylight hours.
- Spring (March-May) is highly variable—early March still has slush and frosts; by mid-May weather stabilizes and warms noticeably.
- Afternoon thunderstorms are common in summer; bring an umbrella or rain jacket June-August.
- Christmas markets (late Nov–early Jan) are popular but extremely crowded; book hotels months ahead.
- Prague's architecture and riverside settings mean summer heat (30°C (86°F)+) feels more oppressive than in seaside cities.
- Snowfall is frequent but light; complete snow cover is typical in January-February but melts quickly.
