What to Pack for an Alaskan Cruise: A Practical Guide for Every Kind of Explorer

Planning an Alaskan cruise is an exciting adventure—glaciers, wildlife, and rugged landscapes await! But packing for this trip can be a bit tricky, especially if you're used to the summer weather in Western Pennsylvania. Even in July, Alaska can feel more like early spring or late fall back home. Here’s a guide to help you pack smart, stay comfortable, and make the most of your cruise—whether you're kayaking near glaciers, hiking through national parks, or simply enjoying a day of scenic cruising from the ship.

When Is Cruise Season in Alaska?

The typical Alaskan cruise season runs from late April through early October, with the most popular months being June through August. Each month brings slightly different weather and wildlife viewing opportunities:

• May–June: Cooler temps, fewer crowds, and blooming wildflowers.

• July–August: Warmer days (by Alaskan standards), peak wildlife activity, and longer daylight hours.

• September–October: Fall colors, fewer bugs, and a higher chance of rain.

Weather: Cooler Than You Think

Even in the heart of summer, daytime highs often range from 50°F to 65°F, with cooler mornings and evenings. Layering is key! You might start the day in a fleece and end it in a rain jacket. Compared to Western Pennsylvania summers, Alaska’s climate is much milder and often damp—so plan accordingly.

My wife, Amanda, and I dressed in layers for our day of hiking. It allowed us to shed layers as the day warmed up.

A Word About Mosquitoes

Yes, Alaska has mosquitoes, and lots of them—especially in June and July, and particularly if you're venturing inland or into forested areas. They're not usually a problem on the ship, but if you're planning hikes or excursions, bring insect repellent and consider lightweight, long-sleeved clothing for protection.

What to Pack: Essentials for Every Traveler

Here’s a breakdown based on the type of activities you might enjoy:

For Everyone

• Waterproof rain jacket (with a hood)

• Warm layers: fleece, thermal tops, or a light down jacket

• Comfortable walking shoes (water-resistant if possible)

• Hat and gloves (yes, even in summer!)

• Binoculars for whale watching and wildlife spotting

• Sunscreen and sunglasses (glaciers reflect a lot of light!)

• Daypack for excursions

• Motion sickness remedies, just in case

For Wildlife & Scenic Tours

• Camera with zoom lens

• Notebook or travel journal

• Light blanket or shawl for chilly deck viewing during your Inside Passage or Scenic Cruising days

For Hikers & Adventurers

• Hiking boots or trail shoes

• Moisture-wicking base layers

• Bug spray with DEET or natural alternative

• Reusable water bottle

• Trekking poles (optional but helpful on uneven terrain)

For Kayakers & Water Excursions

• Quick-dry clothing

• Waterproof gloves

• Dry bag for electronics and valuables

💡 Important Tip: Keep all travel documents—including your boarding pass, passport or ID, and any critical medications—in your carry-on bag. When you drop your luggage at the pier, it may take several hours to reach your stateroom. You’ll need these items handy to board the ship and stay comfortable during the first few hours onboard.

Bonus Tips

• Laundry services are often available on board, so you can pack lighter. Nobody ever regrets not packing 3 suitcases worth of clothes. But you will regret lugging all that around to and from the port.

• Formal nights may require dressier attire, so check your cruise line’s guidelines.

• Packable rain pants can be a lifesaver on wet excursions.

Whether you're chasing whales with your camera or sipping cocoa on the deck, packing smart will help you enjoy every moment of your Alaskan cruise. Safe travels—and don’t forget to leave room in your suitcase for souvenirs!
