Visiting Czech Republic
In general, there are many places to see and events to attend in the Czech Republic at any time of the year. For example, if you want to go sightseeing and visit castles and chateaux, you should come between early May and late September. Although some monuments and most museums and galleries are open all year round, during summer there are various accompanying events taking place at castles and chateaux that you should not miss.
April and October
The months of April and October are interim periods for sightseeing, when you can enjoy a more peaceful atmosphere, but you should also expect cooler weather, often around 10°C. If you wish to visit in winter, you should expect that some places will be closed. It is important to check opening hours in advance.
July and August
July and August are months of school holidays and vacations and the number of visitors is much higher, but interiors of castles offer a pleasant respite from the hot summer sun, when temperatures often rise above 30°C.
Time for winter sports
If you want to engage in winter sports, then the Czech mountains are usually covered with snow from December to March. Temperatures in the mountains during that period are constantly below zero, sometimes dropping as low as –20 or –30°C. In major winter resorts, all important slopes are conditioned with snow-making machines if necessary.
All other activities can pretty much be performed in any season, including walks in the countryside, rambling, biking, visiting spas or enjoying entertainment events and shopping. It is entirely up to you to choose from the warmer days (July and August), blossoming spring (April through June), fragrant and colorful autumn (September and October), or the chilly winter (mid-November to March).
