The town of Banff is in Canada’s famous Rocky Mountains, at about 1,400m above sea level in the south west of the country. Light snow could still fall in May and the surrounding hills of Sulphur Mountain, Mount Rundle, Cascade Mountain and Mount Norquay stop the air getting too warm. The higher you travel the lower the temperature falls.
