Ketchikan is Alaska's southernmost cruise port and often the first stop on an Inside Passage itinerary. The city sits on Revillagigedo Island and is famous for its world-class salmon fishing, massive totem pole collections, and lush Tongass National Forest. Creek Street — a historic boardwalk built on stilts over a salmon stream — is one of Alaska's most photographed spots.
Ketchikan in August offers pleasant temperatures, with highs around 66°F and comfortable lows near 53°F. August sees roughly 18 rainy days, so waterproof layers and flexible plans are wise. Showers are often short-lived but can be intense. Still warm, very popular
This is one of the most popular months to visit Ketchikan, so book shore excursions early — the top snorkeling spots and tours sell out fast. Lightweight layers work well: a light cardigan for evenings on deck and breathable tops for port days cover most conditions.
