I was on the Infinity in Alaska on July 13 thru July 20 and the weather was beautiful. No rain and was not cold at all. I wore jeans and short sleeve shirt during the day and a long sleeve shirt at night. I'm from Florida and really expected it to be alot cooler. The only day it was cold was the day we cruised Hubbard Glacier. I did wear a coat when we were on the balcony.
