The weather in Poland is quite unpredictable. The best time to visit the country is during summer, which is from May to October, when the sun is up and the weather is warm.
Summer in Poland can be feel hot even if the temperature reaches only 20–25 °C (68–77 °F) because the humidity level is high.
On the other hand, winter can be extremely cold, with temperatures dropping to –20° C (–4 °F).
The tourist season is at its peak from July to August. This also marks holiday season for students.
Places like Krakow and Warsaw as well as the Baltic beaches can be really crowded during this time, and it is advisable that you get a reservation way ahead of time.
In fact, the place is so crowded, the empty schools (because it’s school break) also become hostels for backpackers and tourists on a budget, since most of the hotels are already fully booked.
If you dislike crowds, it’s best to visit Poland during the months of September to October. These months may not be as warm as July and August, but autumn is in full bloom, so the weather is ideal for other outdoor activities. In addition, a lot of cultural events are held during this period.
If you wish to go on a ski vacation, the Polish mountains are spectacular during December and are perfect for skiing. Zakopane and the Tatra Mountains are considered Poland’s winter capitals, and they have the best facilities for skiers.
