Climate and weather – Poland’s climate can be described as a temperate climate with relatively cold winters and warm summers, which is greatly influenced by oceanic air currents from the west, cold polar air from Scandinavia and Russia, as well as warmer, sub-tropical air from the south. In summer time temperature is about 25-30°C. In winter, polar-continental fronts often dominate, bringing cold, frosty weather with temperatures far below zero and sometimes heavy snowfall. The late summer and autumn months are often influenced by dry, sub-tropical, continental air mass that bring plenty of warm days. In this time it is close to 0 degree, while winter is very raw, it is even -15°C.
