Prague has four full seasons: Winters often average below 32 degrees, and summers—especially during July and August—can rise up to the 90s (but on average rest in the 80s). Summer is the tourist high season. The city is best discovered on foot, which makes the warmer temps ideal. And although there are short bursts of rain, they usually don’t last too long. In summer, not a weekend passes without an outdoor concert—sometimes on stages floating in the Vltava River—and not a day passes without multiple performances in dozens of historic churches.
Spring ushers in gorgeous blooms in the city’s gardens and parks. With competing influences from Siberia and the Atlantic, the weather can be a bit unpredictable (thunderstorms, heat waves, deep freezes), so come prepared for anything. Fall (September–October) is quite pleasant as well. The days are long and warm, and you can usually bet on a sunny sky. These two seasons bring shorter lines and the opportunity to save some money on accommodations and flights.
Winter is the least popular time to visit—with the exception of the Christmas holidays, when the bridges and rooftops are covered in snow and are postcard-charming. The Prague Christmas markets are legendary, sitting in the middle of the city center lit up with holiday lights and trees, creating a fairy-tale winter wonderland.
Prague has a long history of culture, and it extends throughout the year: Take Febiofest, one of the largest film festivals in Central Europe (March); or Prague Spring (May–June), a festival of classical music that’s been going strong since 1946; or the Prague Writers’ Festival (April), one of the oldest in Europe.
