I was in Juneau recently and didn't see any ski areas there. It's not a very big place. There are only 28,000 people that live there and it is Alaska's third biggest city. Fairbanks in #2 at 30,000 and Anchorage is #1 at 282,000. In Anchorage, there are a few places to go snowboarding. The ones I'm familiar with are Hillberg (need to be military or know somebody who is), Hilltop, and Alayeska. Hilltop and Alayeska are bigger and better than Hillberg so I'm told. But the season here is coming to a close. I am new to barding and have been doing it at Hillberg. They close for the season at the end of this month and don't open back up again until the end of November. Hilltop and Alayeska will be open for another couple of months as long as there is snow. It's already warming up here. It's light from about 7:30 in the morning until 9pm at night right now. In the summer, it's light all the time. That sun warms it up and melts the snow. I doubt you'll be able to do any boarding without going a significant distance from where your cruise ship is going to stop. I'm farther north than any of those places you'll be stopping. It gets warm here in the summer. 70's or so. You'll probably see snow year round, but you won't be able to get to it without a helicopter.
