Check the live forecast above before heading out in Whitehorse, as conditions can shift quickly in this subarctic climate. The city’s weather is defined by cold winters, mild summers, and dramatic seasonal swings in daylight hours.
What makes Whitehorse’s weather unique?
Whitehorse sits in a rain shadow of the Coast Mountains, giving it a semi-arid subarctic climate. This means less precipitation than most of Canada, with annual snowfall around 145 centimetres. Winters are cold but often drier than other northern cities, while summers bring long daylight and comfortable highs near 20°C. The Yukon River moderates extremes slightly, so overnight lows in winter typically stay above –30°C, though colder snaps occur.
How does the weather change through the year?
Winter (November to March) sees average highs from –5°C to –15°C, with December the darkest month. Spring arrives quickly in April, with melting snow and increasing sun. Summer (June to August) offers 18–20 hours of daylight, with July the warmest month. Autumn cools fast in September, and snow often returns by October. For a detailed look, check the Canada weather hub or compare with Edmonton weather for a similar continental feel.
What is the best time to visit Whitehorse for mild weather?
Late June through August offers the warmest temperatures (highs near 20°C) and the most daylight, ideal for outdoor activities. July is the peak month for comfort and festivals, though mosquitoes are active.
Does Whitehorse get extreme cold warnings?
Yes. Environment and Climate Change Canada issues extreme cold warnings when wind chill values drop below –40°C. These are most common in December and January, though dry air often makes the cold feel less biting than in humid regions.
How much snow does Whitehorse get compared to other Canadian cities?
Whitehorse receives about 145 cm of snow annually, less than cities like Ottawa (235 cm) or Calgary (135 cm). The dry climate means snow is often light and powdery, and Chinook-like winds can reduce accumulation.
