Baffin Bay pack ice. Winds are predominantly north-western through the whole year. South-eastern and eastern winds are common in July and August. Between May and July (sometimes April), a significant portion of navigable open water (polynya) forms at the extreme north of the bay, presumably due to the relatively warm Greenland Current. With an area of about in summer, it is the largest polynya of the Canadian Arctic and covers the Smith Sound between the Ellesmere Island and Greenland.

The separation from the south west region, is that the south west has never had roads or other technical links back to the east coast.
