Juneau is Alaska's capital, and you can reach it only by sea or air. It sits between steep coastal mountains and the Inside Passage, within reach of whale watching, glacier hikes, and float-plane trips. The Mendenhall Glacier is just 12 miles from downtown, one of the easier glaciers in the world to reach on a port day.
Juneau in October brings cooler conditions, with highs around 47°F, so pack layers alongside your warm-weather gear. October sees roughly 22 rainy days, so waterproof layers and flexible plans are wise. Showers are often short-lived but can be intense. Wet and cold — end of cruise season
Crowds are moderate in October, making it a good balance between availability and weather. Dress in layers: a waterproof shell over a mid-layer handles the range between cool mornings and afternoon port temps.
