Averaged from the last five years of March 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 March brings cooler conditions, with highs around 45°F, so pack layers alongside your warm-weather gear. March sees roughly 18 rainy days, so waterproof layers and flexible plans are wise. Showers are often short-lived but can be intense. Rain continues, snow possible
Crowds are moderate in March, 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.
