I just got back last week from Alaska on the Radiance. We had one very sunny day (swimming pool weather), two partly sunny days, one cold and rainy day ( Hubbard Glacier) the rest overcast. You could wear a light jacket every day but at Hubbard Glacier. I was on the Oosterdam a few months ago and we were in Juneau with her last week, I have a great picture of the Oosterdam in Juneau. If you want to see it, e-mail me...or wait for my photo gallery of Frank's Radiance in a few more days.
Frank....Thanks for the information. After several weeks of temps in the mid to high 90's here in the DC area we're looking forward to the cooler weather of Alaska! With any luck we'll get a few sunny days.
