If you want to avoid the crowds and take advantage of lower prices, May, early June and September are the best times for an Alaska cruise. In May and early June the weather is drier; in September there are noticeably less mosquitoes than during the height of summer.
Save. The weather in Alaska can be a bit unpredictable at times, even in July, so making sure you are prepared for anything is essential. An Alaskan cruise is not the same as cruising the Caribbean. Packing the wrong items will leave you stranded on board, possibly even in your cabin, not enjoying what you came to see.ther basic items for an Alaskan cruise should be good walking shoes, comfortable clothing, a shade hat and a good pair of sunglasses. Remember that it stays light almost 18 hours a day in the inside passage.
