Best Time to Visit Prague
Prague is a year-round destination, but April through June and September through October stand out. Spring brings mild temperatures (12C to 20C), the city emerging from winter, and Prague Spring International Music Festival in May. The Old Town Square Easter Market in April is one of central Europe's most colorful. Summer (June to August) is the peak tourist period. Temperatures reach 24C to 28C. The Charles Bridge and Old Town Square are genuinely crowded with walking tours and photography groups. Morning visits before 9am and evening walks after 8pm offer calmer experiences at the main sights. October has golden light, comfortable temperatures around 10C to 15C, and fewer tourists than summer peak. The Czech beer harvest in October and Burčák (young wine) events add a local seasonal dimension. December's Christmas markets at Old Town Square and Wenceslas Square are among the most celebrated in Central Europe, and January is cold (-2C to 3C) but historically the cheapest month to visit.
