Cruising Norway in July for 12 nights on the Apex (Stavanger, Olden, Flam, Tromso, Honningsvag, Kristiansand, artic circle). Online weather says 50's and 60's F. Has anyone cruised Norway in July and what type of weather can we expect? What clothes to pack (jeans, sweatshirts, pullover sweaters, long underwear)? I assume layers, but how many layers. Take a jacket or coat?
