I’d be concerned about any cold weather cruise: Alaska, Antarctica, Greenland, Norway and the Baltics etc.
Alaska weather varies a lot, but I think highs are almost always above 50 in any location that has cruises during the cruising season. Mornings can certainly be colder than that though.
Around the glaciers, especially on a windy day, it can be way too cold for me to consider keeping a window open for more than a few minutes.
