Juneau is Alaska's capital and the gateway to some of the most spectacular wilderness on earth. Accessible only by sea or air, it sits between steep mountains and the Inside Passage — a dramatic backdrop for whale watching, glacier hikes, and float-plane adventures. The Mendenhall Glacier, just 12 miles from downtown, is one of the most accessible glaciers in the world.
Juneau in January brings cooler conditions, with highs around 34°F — pack layers alongside your warm-weather gear. January sees roughly 18 rainy days, so waterproof layers and flexible plans are wise. Showers are often short-lived but can be intense. Cold, dark, and very wet — off season
Crowds are moderate in January, 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.
