September is a rainier time in Alaska. Just got off the
DCL Alaska cruise that sailed August 29-September 5. It rained a bit half the afternoon in Juneau (September 2) and all day in Ketchikan (September 3). It also rained a bit off & on our last sea day September 4 and early the morning of our return to Vancouver before we got off the ship. There was some rain predicted for Skagway that never came, but at least one port excursion out of town that day was cancelled due to weather…not sure if it was because of rain out of town or winds as it was very windy in Skagway. Most of the rain was light soft rain, nothing really heavy.
That being said, Alaska is beautiful! And the rain didn’t really negatively impact the cruise, but then a lot of people weren’t in the pools as it was cooler with temps in the 50s Fahrenheit. We had rain coats & umbrellas for off ship. The only day we were out in the rain was Ketchikan, and that was a light, soft rain as it rains a lot in Ketchikan. None of the rainy days had rain very hard when we were in the ports. Our sail back into Vancouver, at around 0500-0600, was the hardest rain we saw all trip before it stopped as we were docking.
For context, I’m in southern California where it never rains, so any rain is more than I’ve seen this year, and I didn’t think the Alaska rains were bad. And it can rain most any time in Alaska; I was on an Alaska cruise in May 2015 where we had sunny 70-degree temps each day and locals were saying that never happened, and it then poured rain every day the following week.
If you want to track the amount of rain happening this year for your proposed travel dates next year, go to
www.noaa.gov and click the Find Your Local Weather at the top left. Type in the city, ie Skagway, hit Go. When the brief results come up, click See full local forecast, then scroll down below the map on the right under Additional Resources to Hourly Weather Forecast & click that. It will take you to more detailed information where you can see in 6-hour increments how much rain is expected. Within 24-36 hours it is most accurate in my experience; farther out things can change but you can get a general idea. I like this site because while a general forecast will tell me it’s going to rain in the afternoon, this will tell me both whether it’s likely, occasional, or a slight chance, and also whether it’s less than a quarter of an inch or more than an inch or two during those six hours.
