Weather and Seasons

Add to my moments

Banff National Park has a subarctic climate with cold, snowy winters and mild summers. It has been said that the most reliable characteristic of Banff & Lake Louise’s weather is its unpredictability. Be prepared! Check the current conditions and forecast here.

Summer (July - September)

Banff enjoys warm, sunny summers, but cool temperatures are not uncommon. Being at an elevation of above 1,400 metres (4,600 feet), it cools off significantly during the night. July is the warmest month, with average highs of 22°C (72°F). 

Fall (October - December)

Autumn in Banff & Lake Louise sees cool mornings which warm up with the sun. By mid-October there are often frosts on the ground in the morning and leaves start to fall. Snow will likely start to cover the peaks and sometimes dust the valley floor.  

Winter (January - March)

The winter air in Banff & Lake Louise tends to be cold and dry, but it is warmer than similar mountainous areas in Alberta due to the Chinook winds. 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 into the minus thirties celsius.

Spring (April - June)

During springtime in the Canadian Rockies you might be enjoying summertime temperatures during the day while a good amount of snow lingers on the ground. The average high temperature at this time of year is 10°C (50°F).
