winter ocean temperature average
The Arctic consists of ocean that is largely surrounded by land. As such, the climate of much of the Arctic is moderated by the ocean water, which can never have a temperature below â2 Â°C (28 Â°F).he winter ice cover allows temperatures to drop much lower in these regions than in the regions that are ice-free all year. Over most of the seas that are ice-covered seasonally, winter temperatures average between about â30 Â°C and â15 Â°C (â22 Â°F and +5 Â°F).
