Weather in Cracow
Kraków has an oceanic climate (Cfb) according to the Köppen climate classification system, one of the easternmost localities in Europe to do so. A mere 100 km (62 mi) north-east of Kraków (east of Tarnów, and north of Kielce), the January mean dips below ?3 °C (27 °F) and thus becomes continental (Dfb) in nature. The Kraków climate is also influenced by its far inland position, with significant temperature differences between seasons. Average temperatures in summer range from 18 to 19.6 °C (64 to 67 °F) and in winter from ?2.0 to ?0.6 °C (28 to 31 °F). The average annual temperature is 8.7 °C (48 °F). In summer temperatures often exceed 25 °C (77 °F), and even 30 °C (86 °F), while winter drops to ?5 °C (23 °F) at night and about 0 °C (32 °F) at day; during very cold nights the temperature can drop to ?15 °C (5 °F). Since Kraków lies near the Tatra Mountains, there are often occurrences of halny blowing (a foehn wind), causing temperatures to rise rapidly, and even in winter reach up to 20 °C (68 °F).

Historical facts - after 1918
After the war, under the Polish People's Republic, the intellectual and academic community of Kraków was put under total political control. The universities were soon deprived of printing rights and autonomy.63 The Stalinist government ordered the construction of the country's largest steel mill in the newly created suburb of Nowa Huta.64 The creation of the giant Lenin Steelworks (now Sendzimir Steelworks owned by Mittal) sealed Kraków's transformation from a university city to an industrial centre.65 The new working class, drawn by the industrialisation of Kraków, contributed to rapid population growth.
In an effort that spanned two decades, Karol Wojtyła, cardinal archbishop of Kraków, successfully lobbied for permission to build the first churches in the new industrial suburbs.6566 In 1978, Wojtyła was elevated to the papacy as John Paul II, the first non-Italian pope in 455 years. In the same year, UNESCO placed Kraków Old Town on the first-ever list of World Heritage Sites.

Worth to know
The Kraków-Częstochowa Upland, also known as the Polish Jurassic Highland or Polish Jura (Polish: Jura Krakowsko-Częstochowska), is part of the Jurassic System of south?central Poland, stretching between the cities of Kraków, Częstochowa and Wieluń. The Polish Jura borders the Lesser Polish Upland to the north and east, the foothills of the Western Carpathians to the south and the Silesian Upland to the west.
The Polish Jura consists of a hilly landscape with Jurassic limestone rocks, cliffs, valleys and vast limestone formations, featuring some 220 caves. The relief of the upland developed since the Paleogene, under climatic conditions changing considerably. Its main component is a peneplain, crowned by monadnocks, rocky masses that resisted erosion, generated as hard rock on Late Jurassic buildup surrounded by less resistant bedded limestone of the same age.1 The Polish Jura is visited by roughly 400,000 visitors a year. Part of it belongs to the Ojców National Park, the smallest of Poland's twenty national parks, ranking among the most attractive recreational areas of the country.2
