What to Wear on an Alaska Cruise?
Quick answer
For an Alaska cruise, pack layers: a waterproof rain shell, a fleece or insulated mid-layer, long pants, and a warm hat and gloves. Alaska stays cool and wet even in summer, so dressing in removable layers keeps you comfortable on deck and ashore.
The key to dressing for an Alaska cruise is layering, not heavy coats. Even in midsummer the weather is cool, breezy, and often wet, and it can shift from sun to rain within an hour. A waterproof shell over a fleece over a base layer lets you add and shed warmth as the day changes, which beats packing one bulky parka.
The core layering system
Build your wardrobe around three layers you can mix and match:
- Base layer: long-sleeve shirts and a couple of thermal tops for cooler glacier days.
- Mid layer: a fleece or light insulated jacket for warmth.
- Outer layer: a waterproof, windproof rain shell, the single most important item you’ll bring.
Add long pants (jeans or hiking pants), a warm hat, light gloves, and a scarf. Waterproof, comfortable walking shoes matter more than anything fashionable, since shore excursions involve trails, docks, and damp ground.
How the months differ
Conditions change across the May-to-September season:
- May and September are the shoulder months, cooler and with more chance of rain, so lean toward warmer mid-layers and definitely pack gloves and a hat.
- June through August are milder, with long daylight hours and occasional warm afternoons, but mornings on deck for glacier viewing still call for a fleece and shell.
On glacier and whale-watching days, the open deck is windy and cold regardless of the month, so keep that warm layer handy.
Don’t forget the ship and ports
Evenings on board follow normal cruise dress codes, so pack one smart-casual outfit and something for formal night if your line has one. For ports, a small daypack helps you carry layers, a rain shell, sunglasses, and a reusable water bottle.
Pack for cool and wet, hope for sunny and mild, and you’ll be ready for whatever Alaska sends your way.
