Banff Sunshine Snowfall Data & Powder Probability

Snowfall patterns over the last decade

Across ERA5 reanalysis snowfall records from 2015 to 2025, Banff Sunshine Village averages 303cm (119 inches) of snowfall a year, with the November-through-April season delivering about 200cm of that total. December is the heaviest calendar month in the 10-year average at 40.1cm, narrowly ahead of November at 38.8cm and March at 35.8cm; April (32.7cm) and February (30.1cm) fill out the season, with January the lightest mid-winter month at 22.0cm — an unusual midwinter low for a major Rocky Mountain resort. Ranked by powder probability — the share of weeks with at least 15cm of fresh snow — December leads at 21%, ahead of November at 14%, March at 13%, April at 11% and February at 9%, with January collapsing to just 2%. The signature is a cold, dry January: total snowfall stays modest because the Arctic air masses that produce Banff's famously light powder also carry very little moisture.

Year-to-year variability is moderate. December snowfall in the 10-year record ranges from 25.3cm in the driest winter to 75.0cm in the wettest — a roughly 3.0x spread, but every December in the decade still cleared 25cm. November swings between 20.4cm and 77.6cm, March between 16.7cm and 64.8cm, and April between 8.8cm and 63.4cm. January is the most consistent of the mid-season months, ranging from just 7.5cm to 34.4cm — a narrow band that confirms the dataset's low-January signal is structural, not a single anomaly. A multi-year baseline is more useful for picking travel dates than any single-week Banff Sunshine snow report.

In the context of the Canadian Rockies and adjacent BC resorts tracked here, Banff Sunshine's 303cm annual average is at the lower end of the regional cluster: neighbouring Lake Louise records 321cm, Kicking Horse 281cm, and Revelstoke (further west on the Powder Highway) 431cm. What distinguishes Banff Sunshine in the record is snow quality rather than volume — the cold, dry Arctic air that dominates January at the Continental Divide produces some of the lowest-density snow on the continent, but it also caps total accumulation. The 2,730m summit and Banff National Park altitude preserve that snow quality through one of the longest seasons in North America (early November to late May). For peak powder probability the late-November through December window is the most reliable in the record; January's 2% powder probability means trips in that month are driven more by cold dry-snow conditions than by fresh powder frequency.

Snow & Weather Conditions

We use 10 years of historical data to help you plan — not a live snow report.

Alberta's Canadian Rockies receive dry, cold snow driven by Arctic air masses. Chinook winds can bring warm spells, but the consistent cold ensures excellent snow preservation. A lofty position in the mountains translates to reliable subzero conditions for much of winter. This altitude sweet-spot catches the brunt of incoming weather systems while keeping the base firm and well-preserved. Season-long totals generally land between 6 and 10 metres, translating to a robust mid-winter base well above 2 metres.

Best Time to Ski

The best time to ski at Banff Sunshine is December, with 40.1cm average snowfall and 21% powder probability. Based on 10 years of historical snowfall data from PowderDays. Season runs from early November to late May. The Rockies snowpack typically peaks in March. PowderDays' historical tool lets you compare precipitation patterns and find the best travel windows.
