March

Strong option

Spring skiing sweet spot — long days, base snow still 2m+, and Sunshine's legendary slush bumps emerging.

#10 for good weather

December

Strong option

Three ski areas fully open by mid-month and Banff Christmas Market on weekends — the holiday postcard.

#11 for good weather
