Don't remember it being too cold when we weren't on the open RIB's but felt raw with the rain. We walked in every port and while I don't remember the temperatures, we walked comfortably on long walks. Simply prepare to layer and bring along rainwear even if it's the little ponchos you can get in a pouch. Think that what we used once when caught short. If it hasn't already been mentioned when you researched the ports; if you are in search of trinkets/magnets, etc. in those ports you will need to get off early! Slim pickings and you may find yourself with northing to take home (other than junk) if it important to you! Enjoy!!
