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 June brings cooler conditions, with highs around 61°F — pack layers alongside your warm-weather gear. June sees roughly 14 rainy days, so waterproof layers and flexible plans are wise. Showers are often short-lived but can be intense. Best weather — long days and fewer showers
This is one of the most popular months to visit Juneau, so book shore excursions early — the top snorkeling spots and tours sell out fast. Dress in layers: a waterproof shell over a mid-layer handles the range between cool mornings and afternoon port temps.
