Alaska in September 2025

Question

Hello. We are traveling from Seattle on a cruise to Alaska (ports are: Sitka, Juneau, Icy Straight Point-Hoonah, and Ketchikan-Ward Cove). Dated 8/30-9/6.

Does anyone have any recommendations of what to see at those ports and what will the weather be (clothes to pack)? Thank you!

Answer

Traveling to Alaska in late August and early September can be a beautiful experience. The weather is transitioning into fall, so you should expect cooler temperatures, possible rain, and varying conditions across the ports. Here’s a detailed guide for your cruise ports and what to pack.

Weather and Clothing Tips

Average temperatures in Alaska at this time range from 45°F to 60°F (7°C–15°C), but mornings and evenings can be chilly.
Rain is likely — bring a waterproof jacket, rain pants, and waterproof shoes.
Layering is essential: base layers, fleece or wool mid-layers, and a windproof outer layer.
Accessories: hat, gloves, and scarf for cooler mornings, sunglasses and sunscreen for sunny breaks.
Comfortable walking shoes or boots are recommended for excursions and dockside exploration.

Additional Tips

Book shore excursions in advance, especially if you want guided tours or popular activities, as September is still a busy season.
Binoculars are handy for spotting wildlife from the ship or on excursions.
Layered clothing with rain protection allows flexibility if weather changes suddenly.
Evening temperatures can be chilly — consider a warm jacket for deck time on the ship.

Overall, late August to early September in Alaska offers fewer crowds than peak summer, beautiful fall foliage starting in the interior, and good wildlife viewing opportunities. With proper layering and waterproof gear, you can comfortably enjoy all the ports on your itinerary.
