Poland lies in the intermediate moderate climate zone characterized by a wide range of changeable weather conditions. Mazowsze’s climate is characterized by warm summers and cool winters.
Average annual precipitation is 20–24 inches (500–600 mm). Winter commonly begins in early December and continues for approximately 100 days.
