Weather & Seasons

Stunning views of Mount Rundle and Vermilian Lakes

The seasonal weather throughout the Canadian Rockies and around Banff is extremely variable due to high elevation and rugged topography. 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.

Banff Ave in winter

Winter

The winter air in Banff and Lake Louise tends to be cold and dry, but due to the Chinook winds, it is warmer than similar mountainous areas in Alberta. The peaks and ski hills receive large amounts of snow, while the town of Banff normally gets a moderate amount and the hamlet of Lake Louise gets a little more. January is the coldest month, with average lows of -15°C (5°F), but the thermometer can drop to negative thirty degrees Celsius (-22°F). Bring your warmest layers and get ready for the endless winter experiences.

Be sure to pack:
All the winter essentials - an extra warm coat, woolly hat, gloves, thick socks and shoes with good grip (it can get icy around here).

Spring

 Springtime in the Canadian Rockies brings glimpses of summertime temperatures on sunny days, while a good amount of snow lingers both in the valley and the mountains. The park begins to awaken after the winter, with bears coming out of hibernation. Around June is when the lakes begin their annual thaw, with Moraine Lake and Lake Louise melting into their iconic blue waters. The average high temperature this time of year is 10°C (50°F).

Be sure to pack:
Warm layers and a waterproof jacket for the occasional spring rain shower.

Moraine Lake in summer

Summer

Summer in Banff often brings warm, sunny weather, although cool temperatures are not uncommon. The alpine comes to life this time of year, with the lakes taking on their vivid turquoise hues, the wildflowers in bloom, and hiking trails at higher elevations mostly snow free. July is the warmest month, with average highs of 22°C (72°F). Being at an elevation of above 1,400 metres (4,600 feet), the evenings can cool off significantly. If you’re planning a summer visit, be sure to still pack a few warmer layers!

Be sure to pack:
Comfortable walking shoes and a sense of adventure!

Fall in Banff National Park - golden larches

Fall

Fall 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)!
