context_page_description: Poland is a country in Central Europe with an area of 312,679 square kilometres, and mostly temperate climate. with an area of 312,679 square kilometres, and a temperate seasonal climate. Situated on the North-Central European Plain, Poland's mostly flat terrain extends from the Baltic Sea in the north to the Carpathian Mountains in the south. However, within that large plain, diverse small landforms run in bands east to west.
  The Baltic coast has two natural harbors, the larger one in the Gdańsk-Gdynia region, and a smaller one near Szczecin in the far northwest. The northeastern region, also known as the Masurian Lake District with more than 2,000 lakes, is densely wooded and sparsely populated. To the south of the lake district, and across central Poland a vast region of plains extends all the way to the Sudetes on the Czech and Slovak borders southwest, and to the Carpathians on the Czech, Slovak and Ukrainian borders southeast. The central lowlands had been formed by glacial erosion in the Pleistocene ice age.
context_section_description: Poland's long-term and short-term weather patterns are made transitional and variable by the collision of diverse air masses above the country's surface. Maritime air moves across Western Europe, Arctic air sweeps down from the North Atlantic Ocean, and subtropical air arrives from the South Atlantic Ocean. Although the Polar air dominates for much of the year, its conjunction with warmer currents generally moderates temperatures and generates considerable precipitation, clouds, and fog. When the moderating influences are lacking, winter temperatures in mountain valleys may drop to a minimum of −20 °C (−4 °F).
  The spring arrives slowly in March or April, bringing mainly sunny days after a period of alternating wintertime and springtime conditions. Summer, which extends from June to August, is generally less humid than winter. Showers and thunderstorms alternate with dry sunny weather that is generated when southern and eastern winds prevail. Early autumn is generally sunny and warm before a period of rainy, colder weather in November begins the transition into winter. Winter, which may last from one to three months, brings frequent snowstorms but relatively low total precipitation.
  The range of mean temperatures is 6 °C (42.8 °F) in the northeast to 10 °C (50 °F) in the southwest, but individual readings in Poland's regions vary widely by season. On the highest mountain peaks, the mean temperature is below 0 °C (32 °F). The Baltic coast, influenced by moderating west winds, mostly in Świnoujście, Międzyzdroje, Dziwnów, Nowe Warpno, Police and Szczecin, has cooler summers and warmer winters. The other temperature extreme is in the southeast along the border with Ukraine, where the greatest seasonal differences occur and winter temperatures average 4.5 °C below those in western Poland. The hottest cities in Poland are Tarnów, Wrocław and Słubice.
  The average temperatures are rising, however. In the period of 1980 to 2010, there were 19 Decembers without snow, and in the period of 2000 to 2010 seven. December 2006 was the warmest one in Poland since 1779. In most of Poland, average temperatures rose by 3-5 degrees Celsius during the last three decades.
  The average annual precipitation for the whole country is 600 mm (23.6 in), but isolated mountain areas receive as much as 1,300 mm (51.2 in) per year. The total is slightly higher in the southern uplands than in the central plains. A few areas, notably along the Vistula between Warsaw and the Baltic Sea and in the far northwest, average less than 500 mm (19.7 in). In winter about half the precipitation in the lowlands and the entire amount in the mountains falls as snow. On average, precipitation in summer is twice of that in winter, providing a dependable supply of water for crops. The growing season is about 40 days longer in the southwest than in the northeast, where spring arrives latest.
