Seward in April

Summer is peak season for good reason. May brings wildflowers and fewer crowds, but some tour operators haven't started running yet. June hits the sweet spot - long daylight hours, most tours operating, and wildlife is active. July and August are peak everything: peak crowds, peak prices, peak weather. Expect 65-70°F days and rain about every third day. September is underrated if you can handle cooler temps. The crowds thin out, fall colors are spectacular, and you might see northern lights. But tour schedules get spotty after Labor Day. Winter in Seward is harsh and most tourist infrastructure shuts down. The Alaska SeaLife Center stays open year-round, but that's about it. If you're coming for the Iditarod restart in early March, book accommodations way ahead - the town fills up with mushers and fans.
