Yukon weather can be quite variable. One day an Arctic air mass can dominate, and the next day a warm front can move in from the Pacific. Sometimes visitors get to experience all four seasons in one day! With our varied geography and changeable weather, it's important to be prepared for sudden changes in weather and temperature, especially if you are doing outdoor activities.
In summer, the temperature can be plus 30 Celsius and the blazing sun shines around the clock while in winter it can drop to minus 30 Celsius. Above the Arctic Circle, the sun doesn't set on June 21st and it doesn't rise on December 21st.
- Summer is June to August. The sun barely sets. People are full of energy. Days can be hot, and the evenings cool off.
- Fall is September and October. The mountain slopes are vibrant with colour. Temperatures are dropping, especially at night.
- Winter is November to March. Yukon winters are cold, bright and snowy. The low sun reflects off blankets of sparkling snow.
- Spring is April and May. This transition season rolls together the last of the skiing, the arrival of migrating swans and early wildflowers.
What to Wear
Whatever the season, pack a wide variety of clothing. Layering is always a good idea so you can adapt to changing weather and temperatures. When you visit the Yukon, chances are you'll discover the relaxed dress code we know as 'Yukon formal'. Things are casual and comfortable here, and you'll find that clean jeans and shirt are welcome in just about any Yukon establishment.
To be comfortable on outdoor adventures, wear a thin wool or polyester base layer that can wick away perspiration. If you're coming for a winter adventure, check in advance to see if your tour guide provides winter clothing or if you can rent a winter clothing package.
Suggested Packing List
Summer: Pack shorts and T-shirts, but come prepared with plenty of layering options. On an outdoor excursion, always bring along pants and long sleeves. A hat and gloves can come in handy, and a windbreaker is useful at higher elevations. Brimmed hats, sunglasses and sunscreen protect against the intense summer sun. Good walking shoes are a must. If you're going into the backcountry, consider packing a bug jacket.
Fall: You can leave your tank tops at home but bring plenty of light, long-sleeve shirts, sweaters and windbreakers for jaunts around town or in the wilds. Pack a warm hat and gloves, walking shoes, plus waterproof boots.
Winter: A good parka and insulated winter boots are a must. Some companies rent a winter clothing package, and others include winter clothing in the price of their trips. Pack lots of warm clothes and long underwear. Bring wind or snow pants if you have them. Warm hat, gloves or mittens, plus a scarf or neckwarmer are essential.
Spring: Pack long-sleeved shirts, pants, a windbreaker or shell jacket, sweaters, a warm hat and gloves, plus walking shoes and waterproof boots.
