June - July
The months of June and July, in addition to August, are the high season months in Poland, and you will see the longest lines for attractions and highest prices for accommodations around this time. Note that by the second half of June, all Polish children and college students will be on summer vacation, adding to the congestion at tourist sites. School doesn`t return to session until the first week in September.
Temperatures across the country will warm into the low and mid-70s for the duration of the summer, except for Zakopane, which will be a few degrees behind in the upper 60s and low 70s. Lows across the country will be pleasant, in the low and mid-50s. The rainy season will begin for most of the country by June, except for the south of the country, which will already see heavy rains by May. July is the warmest month and also the wettest one. In recent summers, temperatures have risen above 80 degrees during the day. Many hotels and tourist sites have air-conditioning but some do not; be prepared for this.
