The townsite sits on the floor of the Bow Valley at about 1,380 m, ringed by mountains. In a wildfire summer, smoke drifting in from fires across Alberta and British Columbia can pool in the valley and linger, even when nothing is burning nearby. Air can be clear in the morning and hazy by afternoon as the wind shifts.
Smoke season runs roughly July through September. On a smoky day, Parks Canada and the Town of Banff may advise limiting strenuous activity outdoors; trail and viewpoint plans are easy to shift to a clearer day. This reading updates through the day so you can check before heading out.
