Averaged from the last five years of December readings — a guide to what to expect, not a forecast for a particular sailing.
Ketchikan is Alaska's southernmost cruise port and often the first stop on an Inside Passage sailing. The town sits on Revillagigedo Island, known for its salmon runs, its totem pole collections, and the surrounding Tongass National Forest. Creek Street, a boardwalk raised on pilings over a salmon stream, runs through the old part of town.
Ketchikan in December brings cooler conditions, with highs around 39°F, so pack layers alongside your warm-weather gear. December sees roughly 19 rainy days, so waterproof layers and flexible plans are wise. Showers are often short-lived but can be intense. Dark, cold, and wet
Crowds are moderate in December, 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.
