Any weather decision in Banff starts from the light budget. In September the location gets about 12 h 13 min of daylight, with the sun peaking 39° above the horizon — that sets how warm afternoons run, how long outdoor plans stay viable and how much usable photographic light the day contains. The scores above layer the live Open-Meteo forecast on top of that baseline.
