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 May brings cooler conditions, with highs around 54°F, so pack layers alongside your warm-weather gear. May sees roughly 16 rainy days, so waterproof layers and flexible plans are wise. Showers are often short-lived but can be intense. Warming up, wildlife active
Crowds are moderate in May, 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.
