I never know how the weather will be in November in Alberta canada I can be wearing short or in the middle of a blizzard.
It's the same here in the Washington DC area, although I know Calgary gets more snow than we do. It's always safer to arrive in the departure city the day before the cruise.
The other thing you should think seriously about is buying cancellation/interruption insurance. It can make a big difference if something does happen to delay your arrival.
