Weather & What to Expect

Glacier Bay weather is highly variable, even during the peak cruise season from late April to early October. Expect temperatures ranging from 45-55°F (7-13°C) near the glaciers, and potentially warmer temperatures when away from the ice. July is typically the warmest month, but even then, cold air flowing off the glaciers creates a microclimate. Rainfall is common, so waterproof gear is essential. If your cruise itinerary also includes ports like Ketchikan or Sitka, be prepared for similar conditions, as these areas are known for significant rainfall. Remember that wind chill on deck can make it feel significantly colder than the air temperature, especially while viewing glaciers.

The Layering System

A flexible layering system is crucial for staying comfortable in Glacier Bay’s unpredictable weather.

• Base Layer: Opt for a moisture-wicking fabric like merino wool or synthetic materials such as polyester or nylon. These fabrics pull sweat away from your skin, keeping you dry and comfortable, unlike cotton which retains moisture. A lightweight merino wool top is an excellent choice for its warmth, breathability, and odor resistance.

• Mid Layer: A fleece jacket or a lightweight down/synthetic insulated jacket provides excellent warmth. Fleece is affordable, dries quickly, and offers good insulation. Down jackets provide superior warmth for their weight but require more care if they get wet.

• Outer Shell: A fully waterproof rain jacket with taped seams is non-negotiable. Look for a jacket with a hood and a waterproof rating of at least 10,000mm. Breathability is also important to prevent overheating, so consider jackets with features like pit zips.

A moisture-wicking Alaska cruise t-shirt makes an excellent base layer, especially on warmer days or for layering under a fleece.

Footwear

Waterproof and slip-resistant footwear is essential for Glacier Bay cruises.

Your primary shoe should be a pair of waterproof hiking boots or sturdy waterproof walking shoes with good traction. The decks of cruise ships can become slippery, especially when wet, and shore excursions in Bartlett Cove may involve walking on uneven surfaces. Look for shoes with a lug pattern sole for enhanced grip.

A backup option like waterproof sneakers or comfortable walking shoes is useful for onboard activities or drier port days. These provide comfort and support for walking around the ship or exploring towns. Ensure they are easy to slip on and off, especially when transitioning between indoor and outdoor spaces.

Avoid wearing sandals or open-toed shoes, especially on deck, due to the cold temperatures and potential for wet conditions. High heels are also not recommended due to the risk of slipping on deck. Prioritize practicality and comfort over fashion.

Essential Gear & Accessories

• Binoculars: Essential for wildlife viewing; bring a pair with at least 8x magnification. The vastness of Glacier Bay means wildlife is often distant.
• Waterproof Backpack: Protect your camera, spare layers, and valuables from rain. Look for a pack with an integrated rain cover or purchase one separately.
• Camera with Weatherproof Cover: Protect your camera from rain, mist, and condensation. Consider a waterproof housing or a simple rain cover.
• Spare Camera Batteries: Cold temperatures drain batteries quickly. Keep spares in an inside pocket to keep them warm.
• Sunglasses: The glare off the glaciers and water can be intense, even on cloudy days. Polarized lenses are ideal.
• Warm Hat (Beanie): Retain body heat and protect your ears from the wind. Wool or synthetic beanies are recommended.
• Gloves or Mittens: Protect your hands from the cold, especially when spending extended periods on deck. Waterproof gloves are ideal.
• Neck Gaiter or Scarf: Provides extra warmth and protection for your neck and face. A fleece or wool gaiter is a versatile option.

## Onboard vs. Port Day Packing

On sea days or glacier viewing days, prioritize warmth and comfort. Layering is key, so you can adjust your clothing as the temperature fluctuates. Spend as much time as you can on deck. Wear your base layer, fleece or insulated jacket, and waterproof outer shell. Don't forget your hat, gloves, and scarf.

For port days in destinations like Juneau, Skagway, or Ketchikan, consider the specific activities you have planned. If you're going on a hiking excursion, wear sturdy hiking boots and moisture-wicking clothing. For exploring towns, comfortable walking shoes and layers are ideal.

Evening dress codes vary by cruise line. Cunard and Seabourn, for example, often have formal nights. Holland America Line, Norwegian Cruise Line, and Princess Cruises generally have a more relaxed dress code, but smart casual attire is typically expected in the main dining room. An Alaska cruise hoodie or sweatshirt works well for cool deck evenings or casual onboard activities.

## What to Skip

• Too many dressy outfits: Formal nights are less common on Alaska cruises than on Caribbean cruises. Pack one or two dressy outfits at most.
• Cotton clothing (as a base layer): Cotton retains moisture and can make you feel cold and clammy. Opt for moisture-wicking fabrics instead.
• Heavy winter coat: A layering system is more versatile and adaptable to changing conditions than a bulky winter coat.
• Unnecessary toiletries: Cruise ships provide basic toiletries, and you can purchase additional items in port if needed. Pack travel-sized essentials to save space.
• Expensive jewelry: Leave valuable jewelry at home to avoid the risk of loss or theft.
