July is the depth of the Antarctic winter, with sea ice extending hundreds of miles north and temperatures far below zero °F on the high plateau. No ships visit. If you are planning for the coming summer, it’s a useful month to compare ship sizes, activities such as kayaking or camping, and whether a fly-cruise makes sense.
