Alaskan cruise season runs from May through September. The best time to go on a cruise to Alaska depends on your budget and personal travel preferences. If saving money is a priority, book your cruise during the shoulder months of May and September. Many cruise lines offer discounts during these months, particularly in September.
Put it all together, and we peg June 15 - July 15 as the best time to visit Alaska. But not everyone can visit during that month window, and that's no problem. Alaska weather is not predictable. You can come in August and bask in sunshine or in June and face horizontal rain (driving rain plus strong winds).
