If you're traveling the Columbia and Snake rivers during the shoulder seasons (spring and fall), average temperatures range from 65- 85 degrees during the day and cool to around 45-50 degrees at night. Pack a few long-sleeved t-shirts and light sweaters that you can layer over or under your clothes in case the weather gets chilly.
You can pack lighter, if you’re cruising in late June through late August, as daytime temperatures average between 85-95 degrees, dropping to 65-70 degrees at night.
No matter which season you are cruising, comfortable shoes are a must for your daily adventures. A windbreaker, preferably waterproof, is also ideal for watching the everchanging landscapes and native wildlife from your private balcony or the sun deck. Be sure to pack fitness clothing if you intend to use our onboard fitness center and don’t forget your daily medications.
