Weather & What to Expect

Alaska cruises, especially those on the Holland America EURODAM, offer diverse experiences, and the weather is no exception. The 2026 Alaska cruise season runs from April 19th to October 11th, with a total of 4037 port calls planned across 63 unique ships. During this time, average temperatures range from 40°F to 65°F, but expect considerable variation. May and June tend to be drier, while July and August see the warmest temperatures. However, even in mid-summer, rain is common, particularly in ports like Juneau, where misty conditions are frequent. Be prepared for cooler temperatures and potential wind while cruising Glacier Bay or Hubbard Glacier. The weather directly affects your activities; a sunny day in Sitka is perfect for exploring the Russian history, while rain might necessitate indoor activities or a waterproof layer for outdoor excursions in Icy Strait Point.

The Layering System

The key to comfort on an Alaska cruise is the layering system. This allows you to adapt to rapidly changing conditions, from cool mornings on deck to warmer afternoons exploring port towns.

Base Layer: Choose moisture-wicking fabrics like merino wool or synthetic blends. Merino wool offers excellent warmth-to-weight ratio and natural odor resistance, making it ideal for longer excursions. Synthetic base layers are also a good choice, as they dry quickly and are often more affordable. A moisture-wicking Alaska cruise t-shirt can also serve as an effective base layer, especially on warmer days.

Mid Layer: Fleece jackets or lightweight down sweaters provide excellent insulation. Fleece is a versatile option that dries quickly and remains warm even when damp. Down sweaters offer exceptional warmth for their weight but require more care in wet conditions. Consider a zippered fleece for easy temperature regulation.

Outer Shell: A fully waterproof and breathable outer shell is non-negotiable. Look for a jacket with taped seams to prevent water leakage and a hood for added protection. Breathability is crucial to prevent overheating during active excursions. A durable water repellent (DWR) finish can help shed light rain, but a fully waterproof membrane is essential for heavier downpours.

Footwear

Choosing the right footwear is crucial for both comfort and safety on an Alaska cruise. You'll be navigating various terrains, from ship decks to hiking trails.

Primary Shoe: Pack a pair of sturdy, waterproof hiking shoes or trail runners with good traction. These are essential for shore excursions, especially if you plan on hiking or walking on uneven surfaces. Look for shoes with a waterproof membrane and aggressive outsoles to handle wet and slippery conditions. Consider the terrain you'll encounter in ports like Juneau or Sitka, where trails can be muddy and rocky.

Backup Option: Bring a pair of comfortable slip-on shoes or sneakers for onboard use and casual port days. These are perfect for relaxing on deck, exploring the ship, or taking leisurely strolls through town. Choose a pair that is easy to slip on and off, especially when entering and exiting your cabin.

What NOT to Wear: Avoid high heels or dress shoes with slick soles. These are impractical for walking on uneven surfaces or navigating the ship's decks, especially in inclement weather. Sandals are also generally not recommended, as they offer little protection from the elements and can be slippery on wet surfaces.

Essential Gear & Accessories

These accessories will significantly enhance your Alaska cruise experience.

• Compact umbrella: Essential for rainy days in ports like Juneau and Ketchikan.
• Wool or fleece beanie and gloves: Even in summer, temperatures can drop, especially when viewing glaciers.
• Binoculars: Crucial for spotting wildlife from the ship's deck or during shore excursions. Alaska's wildlife is abundant, and binoculars will help you see whales, eagles, and other animals up close.
• Travel mug with lid: Keep your coffee or tea warm while enjoying the scenery on deck.
• Waterproof backpack or daypack: Protect your belongings from rain and keep your hands free during excursions.
• Camera with extra batteries: Cold weather can drain batteries quickly, so bring spares and keep them warm.
• Portable charger: Keep your phone and other devices charged, especially during long days in port.

Onboard vs. Port Day Packing

Your clothing choices should reflect the different environments you'll encounter on board the EURODAM and during your port visits.

Sea Days/Glacier Viewing Days: Dress warmly in layers. An Alaska cruise hoodie or sweatshirt is perfect for cool evenings on deck. Bring a blanket scarf to cozy up while whale watching. Bring a waterproof outer layer and warm hat/gloves for glacier viewing.

Port Days: For ports like Juneau, Sitka, and Icy Strait Point, prioritize comfortable walking shoes and weather-appropriate clothing. Jeans or hiking pants, a moisture-wicking base layer, a fleece jacket, and a waterproof outer shell are ideal. Consider the specific activities you have planned; if you're going on a whale watching tour, bring extra layers and a hat. If you're exploring the town, a lighter jacket may suffice.

Evening Dress Code: Holland America Line typically has a more relaxed dress code than some other cruise lines, but evenings can still be dressier. While formal nights are less common, consider bringing dress pants or a skirt, a button-down shirt or blouse, and a sweater or jacket. Some passengers opt for cocktail dresses or suits, but this is not required. Check your specific cruise itinerary for details on formal nights.

What to Skip

Avoid overpacking these items to save space and weight.

• High heels: Impractical for walking on uneven surfaces or navigating the ship.
• Excessive formal wear: Unless you specifically enjoy dressing up, a few versatile pieces are sufficient.
• Too many pairs of shorts: The weather in Alaska is often cool and rainy, making shorts impractical.
• Bulky, non-waterproof jackets: Opt for a lightweight, waterproof shell instead.
• Expensive jewelry: It's best to leave valuable items at home to avoid loss or damage.
