We sailed on the Golden out of Seattle this past Sept. Had drizzle off and on in Juneau, so a sweatshirt, jeans and rain jacket w/hood did the trick. Skagway was sunny and pleasant... long-sleeved top and jeans. We booked a helicopter tour-glacier hike for the afternoon and wore layered clothing for that. Shirt, sweat-shirt, waterproof jacket, gloves and hat. Temp on the glacier was about 32 degrees....brrrrr. Ketchikan was overcast, but temps were comfortable. If you have any other questions, please feel free to send a PM.
