Climate - Odessa (Ukraine)

Odessa's climate is slightly continental, with cold winters and warm to hot, sunny summers.
The city is located in the southwest of Ukraine, at 46 degrees north latitude, on the Black Sea coast. Not far away is the Dnestr (or Nistru) estuary, more than 10 kilometers (6 miles) wide.
The Black Sea does not mitigate the climate much because it is not very extensive, moreover we are in an area subject to cold air masses from Russia but also to warm ones from southern Europe. Due to the collision between air masses, the wind can blow, especially in winter and spring.
Precipitation is not abundant.
Winter is cold and gray. In stable periods, fog can form. Snowfalls are quite frequent but generally not abundant. Sometimes, cold spells can occur, during which the temperature can drop to -15 °C (5 °F) or even below. During the coldest periods, the sea can freeze. The coldest record is -28 °C (-18.4 °F) and was set in February 1929.
Summer is warm and sunny, although there may be some rainy days. There are pleasant periods, or even quite cool, but also very hot periods, in which the temperature can reach or exceed 35 °C (95 °F). The highest record is 39.3 °C (102.7 °F) and was set in July 2007.
