Have cruised often to Alaska and encountered cool foggy rain, heat, and temperate climates. All about the same time of year - late May, early June, even September. All the same coastal cities and once as far north as Anchorage. Last year we cruised three nights and took land tour through the Yukon into the Alaska interior including Denali, then to Anchorage and out to Homer on the Kenai Peninsula. Never have used the silk underwear I purchased for my first trip. A mid-weight jacket, water resistant, is a great idea. Good walking shoes good idea. Comfortable clothing including jeans good idea. One outfit works for evening... take earrings and necklaces and wear monotones... nobody notices. Everyone has worn themselves out sightseeing. I cannot recommend Alaska enough. This is a gorgeous, world-class beautiful trip!!! ph
