Weather and Wildlife

Banff established itself from humble beginnings as a 26 square hot springs reserve. Banff National Park now consists of 6,641 square kilometers of unparalleled Rocky Mountain scenery, nestled in the heart of the magnificent Canadian Rockies.


While the weather is fairy unpredictable in Banff National Park, it is possible to make some generalizations. July is the warmest month, with average highs of 22°C in the Town of Banff. January is the coldest month with average lows of -15°C, though the mercury can drop into the minus thirties. The relative dryness of the Rocky Mountain air in Banff, however, makes even extreme temperatures more bearable. In winter, visitors must be especially careful of wind chill. A temperature of -20°C on the thermometer may feel like -30°C with the wind chill. Regardless of the season in the Canadian Rockies, the temperature will fall about 1°C for every 200m of elevation gain.

The length of the day in Banff varies greatly throughout the year. Daylight can last as little as eight hours in December. At the end of June, the sun rises at 5:30 am and sets at 10:00 pm. Despite the chilly climate, nearly two million visitors still flock to Banff National Park every year, a testament to the park' great beauty and impressive view of the Rocky Mountain peaks. In the summer, most of the visitors are there for activities like hiking and rafting, but the winter in the Canadian Rockies offers its attractions as well, with skiing and snowboarding.
