Preparing for Whitehorse Weather

Being prepared for the weather in Whitehorse is essential for your comfort and safety. Here are some tips to help you adapt to the local climate.

Dressing Appropriately

Layering is key when dressing for Whitehorse weather. This allows you to adjust your clothing to changing temperatures and activity levels. Start with a moisture-wicking base layer to keep sweat away from your skin. Add an insulating middle layer, such as a fleece or down jacket, to trap heat. Finish with a waterproof and windproof outer layer to protect against the elements.

During the winter, it is crucial to wear a warm hat, gloves or mittens, and a scarf to protect exposed skin from frostbite. Insulated boots with good traction are also essential for walking on icy surfaces. In the summer, lightweight and breathable clothing is recommended, along with a hat and sunglasses to protect against the sun.

Protecting Against the Sun

Despite the cold temperatures, the sun can be strong in Whitehorse, especially during the summer months. The high altitude and reflective snow can increase the intensity of UV radiation. It is important to wear sunscreen with a high SPF, even on cloudy days. Sunglasses are also essential for protecting your eyes from glare.

Staying Hydrated

Staying hydrated is important year-round, but especially during the summer and winter months. In the summer, you can lose fluids through sweat, while in the winter, the dry air can dehydrate you quickly. Drink plenty of water throughout the day, and avoid sugary drinks that can actually dehydrate you.

Preparing for Extreme Temperatures

Whitehorse can experience extreme temperatures in both summer and winter. Be prepared for heatwaves in the summer by staying indoors during the hottest part of the day, using air conditioning or fans, and drinking plenty of water. In the winter, be prepared for cold snaps by dressing in layers, avoiding prolonged exposure to the cold, and having a winter survival kit in your car.

Driving in Winter Conditions

Driving in Whitehorse during the winter can be challenging due to snow and ice. Make sure your vehicle is equipped with winter tires and that you have a winter survival kit in case of emergencies. Drive slowly and carefully, and be aware of black ice, which can be difficult to see. Consider taking a winter driving course to improve your skills.
