When to go Prague ?
The tourist season extends from mid-May to the end of September. Prices are high, especially during the long weekends. It is best to go in April-May or September-October to avoid the crowds, the summer heat and the cold, dry winter climate. The Christmas season is a great time to see Prague under its snowy mantle, but be aware that hotel rates are satellite and it is best to book well in advance.
Winter is cold, sometimes very cold and snowy. In the rest of the country, winter can be an opportunity to discover the Czechs' passion for snow sports.
The beginning of spring can be quite cool, but April and especially May are the most pleasant months to visit Prague and the provinces, as the sun returns.
In summer, it can be hot, but this is often accompanied by rain. The Czechs are outside, on the lawns of parks, in the forests, on hiking trails, by the lakes.
