Located in the Canadian Rocky Mountain range, "Banff" refers to both the town of Banff and Banff National Park.

Overall the climate of Banff is more moderate than many popular destinations in Canada, such as Montreal, Toronto, Winnipeg or Edmonton.

The most important thing to know about the climate and weather conditions in this area is that it can change quickly from moment to moment and place to place. 

At any time of year, layering your clothing is the best approach to dressing so you can adjust to conditions readily.

Spring (April - June)

  • Rain and warming temperatures begin to melt winter away from the valleys in April. However, the high mountain passes and trails remain snow-covered until mid-summer.
  • June is Banff's rainiest month: this combined with snowmelt pushes the rivers to their crests.
