Yukon summers are often sunny and warm and winters are snowy and cold. Spring and fall are times of transition and the weather can be unpredictable. Yukon weather can change quickly any time of the year, so plan to pack accordingly. Layered clothing is always a good idea so you can adapt to changes in temperature and conditions.
