Alaska Cruise Packing List: What to Wear and Pack for Every Type of Weather

Alaska cruise season is right around the corner, and one of the biggest questions travellers ask is: what on earth do I actually pack?

After more than 10 years of cruising to Alaska, I’ve learned that packing for this destination is less about bringing “winter gear” and more about being prepared for everything from sunshine on glaciers to sudden rain showers in port. And yes, I’ve had days where I needed a waterproof jacket in the morning, and ended up with sunburn by the afternoon while sailing through glacier-filled fjords.

Alaska keeps you on your toes.

First, Understand Alaska Weather (This Changes Everything)

The biggest mistake people make is assuming Alaska is cold all the time.

It can be, especially when you’re out on deck sailing past glaciers or if you hit a rainy day in places like Tracy Arm Fjord. But it can also be surprisingly warm once you’re in port. I’ve experienced everything from crisp, chilly sail-ins to full sunshine in Juneau where temperatures climbed into the 80s. Even Glacier Bay can feel comfortable if the wind drops and the sun comes out.

So the real secret isn’t heavy clothing. It’s layers.

The dress code onboard is generally “smart casual” during the day and for most evenings, making it comfortable and relaxed. On select nights, you may see “Evening Chic” dress suggested, where guests have the option to dress up a bit more. However, formal wear is not required, so you can decide how dressed up you want to be.

The Golden Rule: Layers, Not Bulk

If I could give only one piece of advice, it would be this: pack layers you can add and remove easily throughout the day.

You really don’t need heavy winter coats or bulky boots. In fact, most people end up carrying those extra layers around in their arms by lunchtime.

Instead, think light, flexible, and easy to adjust depending on where you are and what the weather is doing.

Clothing That Actually Works in Alaska

Over the years, I’ve found a simple mix of clothing works best. Nothing complicated, just versatile pieces you can build outfits from.

For daytime exploring and port days, I usually pack a mix of jeans or comfortable trousers, along with leggings or soft casual pants. Two pairs of jeans is usually enough, and leggings are perfect for travel days and relaxed onboard time.

If you’re considering fleece-lined leggings, they’re an option for extra warmth, but in my opinion, they’re not really necessary unless you tend to get cold easily.

Not a fan of leggings but still want something comfortable and easy to wear? These casual pants are a great alternative. Made from soft, four-way stretch, breathable fabric, they offer excellent mobility and freedom of movement—perfect for everything from exploring ports to relaxing on deck. Plus, they come in a variety of lengths, so you can find the right fit for you.

You’ll also want a handful of tops you can rotate easily, around three to four shirts works well, plus a couple of sweaters for layering when the temperature drops.For evenings, one nicer outfit or dress is plenty. Most cruise lines, especially on Alaska sailings, are far more relaxed than people expect.

A sweatshirt or fleece is something I always throw in too. You can wear it on deck, in port, or even pick one up locally as a souvenir if you prefer.

Outer Layers: Where Alaska Really Matters

This is where your packing choices make the biggest difference.

A good waterproof jacket is essential. Not heavy winter gear, just something lightweight that will keep you dry during rain showers and windier sail-in moments.

I also like to bring a packable puffer vest. It’s one of those items that quietly earns its place in your suitcase because it works in so many situations. You can layer it under a waterproof jacket, or wear it on its own when it’s dry but cool.

A waterproof poncho is another great backup option. It folds down small, is easy to carry in a day bag, and is perfect for sudden rain in port.

And yes, even in Alaska, a scarf, hat, and gloves can be useful, especially when you’re out on deck during glacier viewing. The temperature drops quickly when the ship is moving and wind picks up.

I also love a good sweatsuit set for this kind of trip. It’s perfect for lounging onboard, strolling around the ports, and even for long flights. Comfortable, easy to wear, and available in a variety of colors, it’s one of those versatile pieces you’ll be glad you packed.

Footwear: Comfort Over Everything

If there’s one thing I always prioritise for Alaska, it’s good walking shoes. You’ll be doing a lot of walking, exploring ports, excursions, and sometimes uneven terrain on hikes or nature trails.

Waterproof hiking shoes are ideal, or at least shoes you’ve treated with a waterproof spray. I really like these waterproof hiking shoes by Columbia—they’re comfortable for long days of exploring and do a great job of keeping your feet dry, even in wet or unpredictable conditions.  These are the hiking shoes my husband has.  He loves them - so comfortable! 

One extra tip that sounds small but matters: wet shoes happen. A lot. I usually bring two pairs so I can rotate them if one gets wet. I also use a waterproof spray on my shoes to help keep them protected and dry during excursions.

And shoe odor eliminators and simple shoe bags help keep everything under control in your suitcase. It’s also a smart idea to protect your clothes from dirty shoes by using shoe bags. They help keep everything in your suitcase clean and organized, especially after excursions where your shoes might be wet, sandy, or muddy.

For onboard time, a pair of sandals or casual shoes is enough, and something slightly nicer for evening dinners if you want it.

Cruise Cabin and Day Essentials

Health, Comfort and “Just in Case” Items

There are a few things that don’t fit neatly into clothing, but make a huge difference once you’re onboard.

Alaska can be unpredictable, so I always include a few comfort and health essentials.

Hand warmers are brilliant for glacier sailings or windy deck days. They’re small, but they make a big difference when you want to stay outside longer.

If you’re heading into the interior or planning any hiking, mosquito repellent patches are incredibly useful. You simply stick them onto your clothing, and they help keep bugs at bay so you can enjoy the outdoors more comfortably without constant bites. Another great option is mosquito repellent bracelets. They’re easy to wear, lightweight, and a convenient choice for both kids and adults. Just slip one on your wrist, and they help provide added protection while you’re out exploring.

While most ships do provide umbrellas, they’re often large and not very easy to carry around. We always pack a compact umbrella, no matter where we’re traveling—it’s lightweight, easy to stash in a day bag, and much more convenient for exploring in port.

The glare off the boat can be very strong, and if you’re lucky enough to get sunny days, you’ll definitely be glad you packed sunscreen! Some of the worst sunburns can happen surprisingly fast on the water. I still remember getting badly burned while lying on our family boat on a bright day—just from the reflection off the white deck without sunscreen.

A good pair of sunglasses is a necessity to protect your eyes and make it more comfortable to enjoy the views, whether you’re on deck or out in port.

Alaska is all about the scenery, and you won’t want to miss a thing. While most cruise ships provide binoculars in your cabin, they’re usually pretty basic. We prefer to bring our own compact, high-powered pair—they’re easy to pack and make a big difference when it comes to spotting wildlife and taking in those incredible views.

For carrying everything while exploring, I prefer a small backpack purse. It keeps your hands free, which is especially useful when you’re taking photos or walking through busy ports.

Reusable shopping bags are also surprisingly useful, especially now that many places no longer offer bags. More and more passengers are using a crossbody style bag. It’s lightweight, secure, and very convenient—you can wear it around your waist or as a crossbody.

Swimsuit and cover-up. You might be thinking, “Seriously… a bathing suit?” Yes! The ship’s pools are open and the hot tubs are running—so definitely take advantage of them.2 pairs of good walking shoes (waterproofing is a smart idea).

I hope this list helps make your packing a little easier. Remember—it isn’t always frigid and snowing in Alaska!
