Planning a Trip to Prague? Here's the Weather
See what weather to expect in Prague, Czech Republic and plan your trip with confidence. Monthly averages from real historical weather data.
Prague's climate swings decisively between seasons — cold, grey winters with highs barely reaching 4°C in January and genuinely warm summers that invite long afternoons along the riverbanks and in the city's many green parks. That seasonal contrast is part of the city's character: the same cobblestone lanes that feel atmospheric under a winter frost come alive in summer with café terraces spilling out across every square.
