Planning an Alaska cruise? You'll want to pack for changing weather—cool mornings, breezy decks, and occasional rain or snow (even in summer). The weather can change from day today, even hour to hour. For example, here are three different trips to Ketchikan...same city, different weather each time:
For this particular trip, I had on a long sleeve shirt, padded vest, hoodie, and rain gear on top, matched with a brimmed hat. This was a rainy and cold day, with temperatures in the 40s.
This was a beautiful day in the low 60s. I had on a T-shirt and hoodie and was very comfortable. As you can see it was a very sunny day.
On this trip, a long sleeve performance shirt was topped with a very lightweight jacket. As the day wore on and it got warmer we were removed the jackets and we were very comfortable.
1. A Waterproof Outer Layer
For me, this one is the most important. Choose a waterproof jacket with a hood or a packable rain shell. Look for lightweight weather protection—Alaska wind can make temperatures feel colder fast when you are wet. Ideally, pick something you can layer over a sweater or fleece.
2. Layering Pieces (Fleece + Thermal Base)
Pack thermal tops and leggings or moisture-wicking base layers for colder days. Bring at least one fleece or warm mid-layer for sitting outside on excursions. Wear the "onion method": thin layers that you can add or remove throughout the day.
3. Comfortable, Waterproof Shoes
Bring shoes with good grip for wet decks and slippery gangways. Water-resistant hiking shoes or supportive walking shoes work great. Consider one pair for ship days and one for excursions if you'll be doing lots of walking.
4. Warm Hat, Gloves, and a Scarf
A beanie or warm hat helps a lot when you're on deck early or late. Pack gloves—even thin insulated ones make a huge difference. A light scarf adds warmth and protects your neck from wind.
5. Binoculars (and a Phone Camera Adapter If Needed)
Wildlife spotting is a big part of Alaska cruises, so binoculars are worth packing. If you plan to take photos through your binoculars, consider a phone adapter. Don't forget a small cleaning cloth for lenses.
6. Sunscreen + Lip Balm (Yes, Even in Cool Weather)
The sun can still be strong in Alaska, especially near snow and water. Pack broad-spectrum sunscreen and SPF lip balm to prevent chapping. Sunglasses with UV protection are great for deck time.
7. Reusable Water Bottle and Snacks
A refillable bottle saves money and reduces waste. Choose packaged, factory-sealed snacks for long hiking excursions like trail mix or protein bars. An insulated bottle is perfect if you're traveling in shoulder seasons or cooler months.
8. Small Day Bag or Crossbody for Excursions
You'll want something lightweight and easy to carry. Look for a bag that holds essentials: phone, wallet, gloves, a rain layer, and binoculars. Choose one with a secure zipper and comfortable strap.
9. Electronics for Memories (Plus a Power Backup)
Bring your camera or phone, chargers, and any necessary adapters. A portable power bank is super helpful for tours and long days away from outlets. The power bank can definitely come in handy if you were on a shift without a lot of outlets in the room for charging.
10. Health and Comfort Essentials
Pack basics like any prescription medications plus a small first-aid kit. Bring motion sickness medication since cruise seas can be unpredictable. These items tend to be very pricey on board or in hotels. Include tissues, hand sanitizer, and any personal comfort items like a travel blanket or eye drops.
Final Thoughts
Alaska cruises are amazing adventures, and packing smart means you'll actually enjoy every moment instead of being uncomfortable the whole time. Check your cruise line's packing list too—especially for the items they ban! Pack light, layer up, and get ready to see some of the most incredible views in the world.
