Seasons & Climate
Banff National Park sees mild summers and cold, snowy winters. It’s been said that the most reliable characteristic of Banff and Lake Louise’s weather is its unpredictability. Be prepared! Make the most of your visit to Banff and Lake Louise by packing for all weather possibilities and checking the forecast and conditions before your trip.
September - November
Autumn sees brisk mornings which warm up with the sun. In late September, the glowing larches take on their spectacular golden colour for a fleeting time, the ultimate fall treat to witness in this place. By mid-October, the leaves start to fall and there is often frost on the ground in the morning. The lakes begin to freeze, and the road to the iconic Moraine Lake closes for the winter. This time of year, snow will start to cover the peaks and sometimes dust the valley floor.
Be sure to pack:
Warm layers for the cold evenings and crisp mornings and don't forget your touque (that's Canadian for warm hat)!
