Weather
September delivers crisp autumn weather with highs dropping to 17°C and lows around 3°C. Rain decreases to about 8 days as the weather pattern shifts toward drier fall conditions. First frost usually hits by month's end.

All Months
Summer means crowds but also the best hiking weather. July and August see temperatures in the 70s, perfect for Lake Louise and Moraine Lake, but expect traffic jams and $400+ hotel rates. September brings fewer people, golden aspens, and crisp mornings – probably the sweet spot. Winter transforms Banff into a snowy wonderland with three ski areas: Sunshine Village, Lake Louise Ski Resort, and Mount Norquay. December through February brings reliable snow and temperatures around 15°F, perfect for skiing but brutal for sightseeing. March offers spring skiing with longer days. Avoid April and May – it's mud season with unpredictable weather and many mountain roads still closed.
