The weather can change quickly in the Yukon. You need to be prepared for just about anything. It can snow any month of the year; it can be blazing hot in summer. In every season, the best advice is to dress in layers, so you can add or subtract what you need depending on what Mother Nature throws your way.
Yukoners tend to wear casual clothes most of the time. Comfort and practicality are fundamental to our fashion sense. Your most important accessory is your camera!
