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.
Best Price: Mid-May to early June and late August to mid-September. The trade-off: Cooler weather, less wildlife activity, and (in September) more rain. Best Weather: For longer days, dry weather, and warm temperatures, the best time to cruise in Alaska is late June through mid-July. We Recommend: Salmon run season (mid- to late July) is when the bears are most active. If youâre interested in whales, however, August is when youâre mostly likely to spot them.
