Weather & What to Expect

Juneau experiences a temperate rainforest climate, characterized by consistent rainfall and moderate temperatures. During the peak cruise season, from late April to early October, expect average temperatures between 55-65°F (13-18°C). July is typically the warmest month, while April and October can be cooler and wetter. This weather pattern affects your day by requiring adaptable clothing suitable for both sunshine and showers, especially if you're planning excursions to Mendenhall Glacier or whale watching tours. Ships visiting Juneau are also likely to call at other ports such as Skagway, Ketchikan, and Sitka; each with its own microclimate, so pack with versatility in mind. Be prepared for quickly changing conditions, with the possibility of sun, rain, and wind all in a single day.

The Layering System

The key to comfortable exploration in Juneau is the layering system. Start with a base layer made of merino wool or a synthetic fabric like polyester or nylon. Merino wool offers excellent temperature regulation and moisture-wicking properties, while synthetics dry quickly and are more affordable. A moisture-wicking Alaska cruise t-shirt also makes a fantastic base layer, keeping you dry and comfortable even during light activity.

For your mid-layer, consider a fleece jacket, a lightweight down vest, or a wool sweater. Fleece is a budget-friendly and versatile option that provides good insulation, while down offers exceptional warmth for its weight, making it ideal for colder days or glacier viewing. A wool sweater provides natural warmth and breathability.

Your outer shell should be a waterproof jacket with taped seams and a hood. Look for a jacket with a waterproof rating of at least 10,000mm to ensure adequate protection from rain. Breathability is also important to prevent overheating; a jacket with a breathability rating of 5,000 g/m²/24h or higher will help you stay comfortable.

Footwear

Your primary footwear for exploring Juneau should be waterproof hiking shoes or boots. Juneau offers a variety of terrains, from paved streets and boardwalks in the downtown area to potentially muddy trails around Mendenhall Glacier and Mount Roberts. Waterproof hiking shoes or boots will provide the necessary traction, support, and protection from the elements. Look for a shoe with a good grip and ankle support.

A good backup option is a pair of comfortable walking shoes or sneakers that can be worn onboard the ship or for casual port days. These will be ideal for exploring the shops and restaurants in downtown Juneau or for relaxing on deck.

Avoid wearing open-toed shoes, sandals, or high heels while exploring Juneau. These types of footwear are not practical for the terrain or weather conditions and can increase your risk of injury.

Essential Gear & Accessories

Here's a list of essential gear and accessories to pack for your cruise to Juneau:

• Waterproof backpack: To carry your essentials and protect them from rain.
• Binoculars: For enhanced wildlife viewing, especially during whale watching tours.
• Camera: Capture the scenery and wildlife; bring extra batteries, as cold weather drains them faster.
• Waterproof gloves: Keep your hands warm and dry, especially on boat tours or near the glacier.
• Warm hat: A beanie or similar hat will protect you from the cold and wind.
• Sunglasses: Even on cloudy days, the glare from the water and glaciers can be intense.
• Sunscreen: Protect your skin from UV rays, even in cooler weather.
• Insect repellent: Mosquitoes and other insects can be present, especially on trails.

Onboard vs. Port Day Packing

On sea days and glacier viewing days, prioritize comfort and warmth. Layering is still key, so pack items like fleece jackets, sweaters, and comfortable pants. An Alaska cruise hoodie or sweatshirt is perfect for relaxing on deck in the evenings.

For port days in Juneau, focus on practicality and weather protection. Prioritize waterproof outerwear, comfortable walking shoes, and accessories like gloves and hats. Remember that Juneau is just one stop on your cruise; ports like Ketchikan and Skagway may have slightly different weather patterns, so versatility is key.

Evening dress codes on cruise ships vary, but generally range from casual to formal. Check with your cruise line for specific guidelines. For most evenings, smart casual attire is appropriate.

What to Skip

Avoid overpacking these items for your Alaska cruise:

• Excessive formal wear: While some cruise lines have formal nights, you likely won't need multiple formal outfits. One or two formal outfits should be sufficient.
• Bulky winter coat: A waterproof, insulated jacket is more versatile and packable than a heavy winter coat.
• Too many pairs of shoes: Stick to comfortable walking shoes, waterproof hiking shoes, and a pair of dress shoes for evenings.
• Expensive jewelry: Alaska is an active destination, and you're less likely to wear expensive jewelry on excursions.
• Cotton clothing (as a primary layer): Cotton absorbs moisture and takes a long time to dry, making it uncomfortable in wet or cold conditions.
