Planning a trip to Juneau, Alaska? Whether you're visiting Alaska on a cruise or traveling solo in the warmth of summer or the chill of winter, wearing the right clothing is essential to fully enjoy your Alaskan adventure.
Juneau Alaska is part of a temperate rainforest with an average of approximately 230 days of measurable precipitation annually.
This means you will see a lot of overcast skies, a high chance of rain, mild temperatures, and unpredictable weather year-round. Dressing in layers is needed to stay comfortable as conditions shift from cool and misty to sunny and warm within hours.
Waterproof outerwear and footwear are key to staying dry, while breathable layers help regulate body temperature. Even in summer, chilly evenings and sudden downpours are common, so packing smart ensures you're ready for whatever Juneau's temperate rainforest climate brings.
Here's your ultimate Juneau packing list, broken down by season, so you can stay warm, dry, and ready for anything.
Year-Round Essentials
Waterproof Jacket: A must-have no matter when you visit. Look for something lightweight and breathable. Locals never bother with umbrellas—waterproof jackets are the way to go especially if you're planning a hike or active excursion.
Waterproof Footwear: Waterproof hiking boots or walking shoes are perfect for trails and wet sidewalks. Fun fact: The classic brown boots you'll spot around town are XTRATUFs—a Southeast Alaska staple for dry feet.
Dress in Layers: Juneau’s weather can change quickly. Pack a mix of t-shirts, long-sleeve shirts, and sweaters.
Base Layer: Start with a lightweight, moisture-wicking fabric that pulls sweat away from your skin, such as merino wool or another natural fiber.
Mid Layer: Add an insulating layer, like a fleece jacket or a sweater, to keep warmth in.
Outer Layer: Finish with a waterproof and breathable shell to protect against wind and rain. A thin, packable jacket made of Gore-Tex® material with a hood will keep you dry and comfortable, even on the wettest days. This outer layer can easily be stowed in your daypack when not in use, ensuring you're ready for whatever the weather brings!
Comfortable Pants: Quick-dry hiking pants or rain pants are a must. Especially if you plan on doing outdoor adventures like hiking, kayaking, or exploring muddy trails. Fun Fact: Juneau is home to over 250 miles of hiking trails, offering a variety of options for all skill levels. From easy strolls to more challenging backcountry hikes, the trails provide breathtaking views of glaciers, mountains, and coastal rainforests.
Accessories: Hat, gloves, and a scarf if you tend to get cold—even in summer, evenings can get chilly.
Backpack: For carrying water, snacks, and extra layers during tours. Use a rain cover or dry bag to keep everything dry.
Sunscreen & Sunglasses: Yes, even in Alaska! Fun Fact: If you manage to get lucky and experience sun in Juneau even on a 65°F (18°C) day, the sun's higher position in the sky can make it feel warmer than the actual temperature. This is because the sun's rays strike the Earth's surface more directly, concentrating energy over a smaller area and increasing warmth.
