The climate in Whitehorse can be described as subarctic and quite dry, which is typical for the northern territories of Canada. Thanks to its location in a valley, the city is often sheltered from the harshest winds, yet the weather here demands respect and proper preparation. Overall, the region is characterized by significant temperature fluctuations between seasons, while extreme heat is an extremely rare phenomenon here.

Winter in Whitehorse is long and frosty: from November to March, average temperatures consistently stay well below freezing, often dropping to -15°C and lower. Summer, on the other hand, is short but very comfortable and mild. In July, the warmest month, the air warms up to an average of +19°C during the day, creating ideal conditions for walks and exploring nature without exhausting heat.

Precipitation in the city is low, although light rain or snowfall can occur quite frequently—up to 14 days a month during the summer and autumn periods. Spring and autumn are fleeting here, serving as quick, cool transitions between the main seasons. Travellers should remember that even in summer, nights can be fresh, so warm clothing will be relevant at any time of the year.

The temperature regime in Whitehorse is characterized by a distinct contrast between seasons, which is typical for the northern latitudes of Canada. The coldest month of the year is traditionally January, with average figures around -16.4°C and night frosts reaching -19.4°C. The warmest and most comfortable time to visit is considered to be July, when the air warms up to an average of 13.7°C, allowing you to enjoy nature without extreme cold.

Winter here is long and severe: consistent sub-zero temperatures set in as early as November and persist practically until April. During the winter months, especially in January and February, one should be prepared for serious frosts, when even daytime highs rarely rise above -11°C. Spring arrives late: March still remains a winter month with an average temperature of -7.9°C, and confident "plus" temperatures are established only by May.

Summer in Whitehorse can be described as cool and fresh; there is no exhausting heat here. In June and August, daytime temperatures reach a pleasant 16–17°C, and in July—about 19°C. It is important for travellers to consider significant daily fluctuations: even in the height of summer, when the sun shines during the day, nights remain cold. For example, in July, the difference between the daytime maximum and nighttime minimum is about 10 degrees, so the temperature can drop to 8.5°C, requiring warm clothing for evening walks.

The climate in Whitehorse is distinguished by its dryness due to the city's location in the rain shadow of the mountains, yet precipitation falls here quite regularly throughout the year. In the winter period, from November to March, when the average temperature stays confidently below freezing (down to -16.4°C in January), precipitation falls exclusively in the form of snow. Snowfalls happen often—from 9 to 12 days a month—but they are generally not heavy, creating a moderate snow cover.

The driest season can be called spring, especially March and April, when the number of days with precipitation is minimal (7–8 days). As it gets warmer in May, snow gives way to rain. Summer and early autumn bring the highest frequency of precipitation: July and October are the leaders in the number of inclement days (up to 14 days a month). In the summer months, when temperatures rise to a comfortable +13...+18°C, rains are usually light and short-lived in nature.

In autumn, the weather changes quickly: already in October, when temperatures drop below freezing again, rains turn into wet snow. Despite the fact that there are more "wet" days in summer and autumn, the total volume of precipitation in Whitehorse remains low compared to other regions of Canada. Therefore, when planning a trip, expect frequent light drizzle or light snow rather than heavy downpours or blizzards.

A trip to Whitehorse requires careful wardrobe preparation, as the climate here is harsh and the weather can be changeable. If you are planning a journey in winter (from November to March), when temperatures often drop below -15°C, the foundation of your gear should be quality thermal underwear, warm woollen sweaters, and a reliable down parka with a hood. Be sure to bring insulated waterproof boots with thick soles, a warm hat, a scarf, and mittens to feel comfortable during walks in the fresh air.

Summer in this part of Canada is quite cool and fresh: even in July and August, daytime temperatures rarely exceed +19°C, and nights can be cold. The best strategy for any season is the principle of layering. For summer trips, pack t-shirts, fleece jackets, and a light windbreaker or raincoat, as precipitation is possible throughout the year. Comfortable and durable trekking shoes will be indispensable for exploring the natural attractions of the Yukon.

Do not forget about important small items that will make the trip more comfortable. Sunglasses and sunscreen will be useful both in winter (due to the bright sun reflecting off the snow) and in summer during the long daylight hours. In the warm season, it is recommended to carry insect repellent, and in the cold season—a rich face cream and lip balm to protect your skin from the dry frosty air.
