How cold are winters in the northern and eastern Bering Sea?

Winters in the northern and eastern portions of the Bering Sea are extreme, characterized by high winds and temperatures ranging from -31° to -49° F (-35° to -45° C). During these months, the northern part of the sea is covered with ice fields that typically reach 4 to 5 feet in thickness, with some hummocks exceeding 100 feet in height.12

This region experiences a harsh climate compared to the southern and western areas of the sea, with a frost-free period lasting only about 80 days. The northern portion also receives significantly less annual precipitation than the south, with most of it falling as snow.1
