We have traveled to Alaska twice in late September pre pandemic, and last year we were on the Bliss to Alaska Oct 15-22. We are always hoping to see the Northern lights but have not had any luck. One night a few years ago, all the people in port were saying it was a perfect night for the lights. The captain turned the lights off on the back of the ship, and a bunch of us sat in the dark looking at the sky. The lights did not show that night, but the stars were amazing. So many more than what we see from home.
The stores are all starting to shut down. This does not bother us because we are there for the scenery.
We have always been lucky with the weather. This past October in Juneau the morning clouds burned off nicely and it turned out to be a beautiful day. The people who when whale watching said they saw quite a few whales and the orcas were particularly playful. The tour guides said it was the first real sunny day they had in awhile. We spent the day at Mendenhall glacier hiking. It was beautiful.
Our ship went to Icy Strait Point instead of Skagway because of rockslide. We did the ziplining through NCL here. It was freezing, windy, raining, sleet, and you couldn't see anything with all the clouds. The people running the zipline couldn't believe NCL was sending people to do this with the weather. My husband did the math in his head, and told the tour guide that NCL had $40,000.00 reasons why they were sending us down the zipline in that kind of weather. Lol.
We had more rain, wind, and fog/clouds in Glacier Gay. The ranger did not come on board because of the weather. I was a bit disappointed because NCL felt it was okay to go ahead and let us zipline down a mountain in this weather, but it was too dangerous to bring a ranger on the ship, but I'm sure they had their reasons and want everyone to be safe.
We were the only ship in every port, and I absolutely loved that part of it.
Sorry for the long post. There are definitely pros and cons to traveling late season in Alaska. There are ten of us going on the Bliss in October this year for my mothers 84th birthday. I will have my fingers crossed the weather is better in Glacier Bay, as that is always my favorite part.....
