I live in Alaska, by all means it is not cold to us. It can still be pretty chilly, all depends what part of June? you can bring shorts, but more than likely you won't wear them. Usually the only people you see in shorts is the people from here. But this summer it was warm, so go ahead and bring a pair. A Must is a jacket, and I would throw gloves in there just in case. Can be very chilly in the evening and mornings. You will have a great time!!!
