Poland's climate has four distinct seasons and is characterized by hot summers and dark, cold winters. Unless you're heading to the Tatras to ski, avoid travel from January to March. Many of the attractions are closed for the season, and the cold and snow make getting around difficult. Note that Kraków and Zakopane are both popular Christmas and New Year's destinations, and hotel prices rise accordingly. Summer brings good weather but more crowds as Poles take to the roads on their summer holidays. September and October are ideal, with fewer crowds and usually reliably good weather.
