What Newcomers Should Know About Calgary Winters

Calgary winters are cold, sunny and quick to change. In January, the coldest month, the average daily high is minus 1.5°C and the average low is minus 13.5°C, the city receives about 139 cm of snow a year, and it records roughly 2,400 hours of sunshine annually, according to Environment and Climate Change Canada's 1991 to 2020 climate normals. Warm chinook winds can push temperatures well above freezing in the middle of winter, then the cold returns.

If you are moving to Calgary from a milder part of Canada or from overseas, this guide covers what to expect month by month, why the weather swings so fast, how snow clearing works, how short the days get, how to get around, and how to stay safe in a cold snap.

1. How Cold Does Calgary Get in Winter?

Winter in Calgary generally runs from November through March. The table below shows the average daily high and low for each month at Calgary International Airport, from Environment and Climate Change Canada's Canadian Climate Normals for 1991 to 2020.

Averages hide the extremes. Short cold snaps can run far below these numbers, and the coldest temperature ever recorded at the airport station is minus 45°C. The flip side is that chinooks can push a mid winter afternoon well above freezing.

2. Why Does Calgary's Winter Weather Change So Fast?

The short answer is chinooks. A chinook is a warm, dry wind that comes down the eastern slopes of the Rocky Mountains and replaces cold Arctic air over southern Alberta. The Canadian Encyclopedia notes that in southwestern Alberta, about one winter day in three is a chinook day, and that temperatures have been observed to rise by 27°C in just two minutes.

In practice, this means a week can start at minus 25°C and end with melting snow and puddles, then freeze again. Watch for the chinook arch, a band of clear sky over the mountains to the west, which often signals warm air is coming. The quick melt and refreeze is also why sidewalks and driveways can turn icy overnight.

3. How Much Snow Falls in Calgary, and Who Clears It?

Calgary averages about 139 cm of snow a year, spread over roughly 55 days with measurable snowfall, so it usually arrives in smaller storms rather than one deep, lasting snowpack. Most of it lands between November and March.

The City of Calgary clears roads in a set order under its Priority Snow Plan:

Two things surprise many newcomers. First, residential streets are usually not plowed, so a vehicle with good tires and some clearance makes a real difference on side streets after a big storm. Second, Deerfoot Trail, Stoney Trail and Tsuut'ina Trail are maintained by the Province of Alberta, not the City.

The biggest one: under the City's snow and ice bylaw, property owners must clear the public sidewalk next to their home down to the bare surface within 24 hours of a snowfall ending. Fines are $250 for a first offence, $500 for a second and $750 for a third within 12 months, and the City can clear it for you and bill a minimum of $150 plus GST and an administration fee. A good shovel and a bag of ice melt or traction grit belong on every newcomer's first shopping list.

4. How Short Are the Days in a Calgary Winter?

This is the adjustment many newcomers underestimate. According to Sunrise Sunset, Calgary gets about 7 hours and 54 minutes of daylight on the winter solstice, December 21, compared with about 16 hours and 33 minutes at the summer solstice. In late December the sun does not rise until well after 9 a.m.

The City of Calgary's First winter in Calgary page notes that cold and darker days can be hard to adjust to, and links to supports for mood and mental health. Getting outside during the brightest part of the day, especially on sunny weekends, helps a lot.

5. How Do You Get Around Calgary in Winter?

• Winter tires are recommended, not required. Alberta Transportation confirms that Alberta has not made winter tires mandatory, but advises four winter or all weather tires for severe winter conditions. Look for the mountain snowflake symbol, which marks tires that meet a snow traction standard.
• Plan for icy walks. Boots with real tread matter more than a heavy coat. The City's newcomer page specifically warns about black ice and walking on frozen ground.
• Use the Plus 15 downtown. The Plus 15 network links downtown buildings through more than 16 km of climate controlled walkways and 86 bridges, open weekdays 6 a.m. to 9 p.m. and weekends and holidays 9 a.m. to 7 p.m. (closed December 25).
• Check conditions before you leave. The City posts snow and road updates, and Calgary Transit posts service changes during storms.
• Keep a winter kit in the car. The City recommends a first aid kit, and many Calgarians add a scraper, blanket, booster cables and a small shovel.

6. How Do You Stay Safe During a Cold Snap?

Environment and Climate Change Canada issues cold and extreme cold warnings based on local temperature and wind chill. In November 2025, the federal government announced that alerts are moving to colour coded levels under a new national weather alert system:

The free WeatherCAN app sends these alerts to your phone. The federal guidance also notes that cold injuries can happen near 0°C, even with little wind, so cover exposed skin and dress in layers on any cold, windy day, not only during a warning. During the coldest days, the City's newcomer page also lists emergency shelter and daytime warming spaces for anyone who needs them.
