Spring (March-May): One of the best times to visit with pleasant temperatures (10-18°C), blooming gardens, Easter festivities, and manageable crowds before peak summer season. May showcases Prague at its greenest with parks and castle gardens in full bloom. The Prague Spring International Music Festival (May-June) draws classical music enthusiasts worldwide. Occasional rain requires light jacket. Highlight: April-May offers ideal balance of good weather and moderate tourist numbers.
Summer (June-August): Peak season with warm weather (20-26°C), longest daylight hours, outdoor festivals, and vibrant street life. Expect large crowds at major attractions, higher accommodation prices, and advance booking requirements. July-August can be hot and humid. Prague's beer gardens thrive, riverside cafés bustle, and evening concerts fill church interiors. Crowding note: Charles Bridge and Prague Castle extremely busy midday visit early morning or late evening.
Autumn (September-November): Excellent visiting season with comfortable temperatures (10-18°C), golden foliage, wine harvest festivals, and thinning crowds after school resumption. September offers summer weather with fewer tourists. October brings Czech beer festivals and Signal Light Festival. November can be gray and rainy but atmospheric with Christmas market preparations beginning. Value season: Lower prices and authentic local experiences increase.
Winter (December-February): Magical atmosphere with Christmas markets (late November-early January), snow-dusted Gothic architecture, festive illuminations, and New Year celebrations. Cold weather (-5 to 5°C) requires warm clothing but creates postcard-perfect scenes. Christmas markets at Old Town Square and Wenceslas Square transform Prague into winter wonderland. January-February offer lowest prices and smallest crowds but shortest daylight and coldest temperatures. Holiday magic: December is enchanting but book accommodations months ahead for Christmas/New Year periods.
