Prague

Here's the thing about Prague that surprises most people: it's actually cold for much of the year. The annual average high sits at just 15°C (59°F), which means even summer doesn't feel sweltering the way it does in southern Europe. If you're picturing yourself sweating through Old Town Square, recalibrate. That said, May through August are genuinely the months when Prague feels alive—the Vltava glimmers, the beer gardens fill up, and you can actually sit outside without a parka.

Each of these four months has a distinct personality. May is the sweet spot if you hate crowds: highs around 20°C (68°F), everything's blooming, and locals are still outnumbering tourists. June brings real warmth—highs creeping toward 23°C (73°F)—plus the white nights start kicking in, so you're getting nearly 16 hours of daylight. July is peak season in every sense: the hottest month (highs around 24°C / 75°F), the most tourists, the highest prices, and the most street performers in the Charles Bridge. August feels like a local secret—still warm (23°C / 73°F), but families are on vacation elsewhere, and there's a slightly slower, more relaxed vibe. Rainfall averages around 640mm annually, spread fairly evenly, so expect a drizzly day here and there even in summer.

Winter, spring, and autumn are essentially off-limits for most travelers, and honestly, I get it. October through March means highs rarely break 10°C (50°F), the days shrink to around 8 hours of daylight, and the city feels genuinely gray. November and February are particularly grim. Businesses don't close, but the magic that makes Prague feel like a fairytale gets buried under clouds and damp. If you do come in winter, expect moody, atmospheric, and photogenic—but also lonely and cold.

Looking at 2026 specifically: Prague's climate isn't shifting dramatically like some destinations, but we are seeing slightly warmer summers than the historical average. May and June 2026 should track close to normal, maybe a degree or two warmer than baseline. This actually tips the scales even more toward visiting in May if you can swing it—you'll get the warmth without the July crowds or August humidity starting to creep in.
