Winter begins in November, but we have the first snow and frosts already in October. Winters are quite cold here. The temperature can fall down to 35-40 degrees bellow zero. We have much snow. The river freezes. But Arkhangelsk is a port with all-the-years round navigation. Ice-breakers make channels for the ships to pass. But not all winters are typical. Sometimes it is abnormally warm (it is above 0). Snow and ice melt. There are even floods. It is a real disaster for people in villages when water comes to their houses. It happens due to global climate change.
