When to Visit Prague

January in Prague is cold and still. Highs reach only 3°C (39°F). Lows hover right at freezing, around 0°C (31°F). Rainfall is light at 18mm. The dampness and low cloud make it feel raw. Crowd levels are low. The city has a quiet, almost melancholy quality. Indoor spaces come into their own. The National Museum. The galleries in the Old Town. The coffee houses. This is a month for slow city exploration rather than marathon sightseeing.

February is essentially January's twin. Highs nudge up to 5°C (42°F). Lows remain at 0°C (32°F). Rainfall drops slightly to 15mm. Snow is still possible. Days are short. A subtle loosening arrives by the end of the month as the light improves. Crowds remain low. Prague in February rewards travelers who don't mind the cold. You can have the Charles Bridge nearly to yourself at dawn.

March brings the first real signs of movement. Highs reach 10°C (50°F). Lows lift to 2°C (37°F). Rainfall sits at 25mm. Some days feel almost warm. Others revert to January's grey chill. The city is beginning to wake up. Outdoor café culture makes tentative appearances on the sunnier afternoons. Crowd levels tick up from their winter low but remain medium-low overall.

April is a turning point. Highs hit 16°C (60°F). Lows sit at a comfortable 6°C (44°F). Rainfall stays at 25mm. The city feels alive again. Parks and gardens start coming into bloom. The Royal Garden and Letná are standouts. Walking the city for a full day becomes a pleasure rather than a cold-weather expedition. Crowds are building but haven't yet reached peak levels. This is one of the more rewarding months to visit Prague.

May is arguably the city's finest month. Highs reach 20°C (69°F). Lows settle at 11°C (52°F). The rainfall increases to 58mm. Most of it comes in short, sharp bursts rather than all-day grey drizzle. Everything is green. The terraces are open. The city is operating at full energy. Crowds are high but not yet at their July peak. Longer days mean you can wander into the evening without feeling the temperature drop too sharply.

June pushes into proper summer. Highs hit 24°C (75°F). Lows sit at 14°C (58°F). Rainfall reaches its annual peak of 69mm. Thunderstorms are more frequent now. They typically arrive in the late afternoon. They clear quickly. The evenings are warm and long. This is peak tourist season in Prague. The Old Town Square and Charles Bridge get crowded during the day. The city's outdoor bar and restaurant scene is at full stretch. Evening light lingers until well past nine.

July is the warmest month, with highs of 26°C (79°F) and lows of 16°C (61°F), and rainfall matching June at 69mm. The crowds are at their maximum. Popular sights can feel overwhelmed in the middle of the day. That said, the evenings are memorable. Warm enough to sit outside until late. The city illuminated. The Vltava catching the last of the light. If you're visiting in July, the early morning hours (before nine) are when Prague belongs to you.

August is nearly identical to July in feel: highs at 25°C (78°F), lows at 16°C (61°F), rainfall easing slightly to 61mm. Crowds stay high into mid-August. They begin a slow retreat as the European holiday season winds down. By the final week of August, there's a perceptible shift in the air. A slight cooling in the evenings hints at what's coming.

September is the month many experienced Prague visitors quietly consider their favorite. Highs drop back to 20°C (68°F) and lows to 12°C (53°F). Rainfall falls to 33mm and the skies tend to clear. The light has that warm, low-angle quality particular to Central European autumns. Crowds thin noticeably from their summer peak. The whole city feels like it's exhaling. Medium crowd levels. Excellent walking weather. The cultural calendar kicking back into gear after summer.

October brings a more pronounced chill: highs at 14°C (57°F), lows at 7°C (46°F), with rainfall at 30mm. The trees in Stromovka and along the river paths turn amber and copper. The city has a textured, slightly melancholy beauty that suits its architecture. This is good sightseeing weather for anyone who runs warm or dislikes summer heat. Crowds are medium-low and dropping.

November is the month Prague starts to close in. Highs fall to 8°C (47°F), lows to 3°C (39°F), and 25mm of rainfall arrives mostly as drizzle and damp grey days. The city's indoor culture, its cafés, theatres, concert halls, compensates considerably. Crowds are low. The atmospheric winter version of Prague is beginning to establish itself, as the month progresses. Worth noting if you're considering a visit: the Christmas markets typically open in late November and immediately draw large numbers to the Old Town Square.

December splits into two distinct phases. Before the markets arrive, early December is quiet, cold (highs of 4°C / 40°F, lows of 0°C / 33°F), and atmospheric in a low-key way. Once the Christmas markets are running, the Old Town becomes extremely busy on weekends. Accommodation rates rise accordingly. Rainfall is 23mm. Snow is plausible, though not guaranteed. The city's festive decoration is impressive. Even with the crowds, Prague in December has a quality that's hard to replicate elsewhere.
