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.
The Alaskan cruise season is relatively short, lasting only from May through September, but is extremely busy. According to the State of Alaskaâs Visitor Volume Report, 1.58 million people visited the state in 2009. August is considered Peak cruise season, with higher prices and more crowded ships, but decent weather and expanded hours at tourist attractions may be worth the extra cost.
