Alaska cruises in June
June has the longest days, around 18 hours of daylight in Juneau and nearly 19 in Anchorage, and some of the summer’s most settled weather. Lupine and wildflowers bloom, king and sockeye salmon runs begin, and humpback sightings are reliable. Families arrive once schools let out, so prices climb toward their peak in the second half of the month.
