Banff in May
Not the best time
May marks real spring in Banff with wildflowers starting to bloom in the valley. Good weather for town exploration and lower elevation hikes, but many mountain trails stay closed by snow.
Weather
May finally feels like spring with highs reaching 15°C, though nights still drop to 3°C. You'll see rain about 10 days this month as snow melts accelerate. The weather becomes more stable, but hiking trails at elevation remain snowy.

All Months
Summer means crowds but also the best hiking weather. July and August see temperatures in the 70s, perfect for Lake Louise and Moraine Lake, but expect traffic jams and $400+ hotel rates. September brings fewer people, golden aspens, and crisp mornings – probably the sweet spot. Winter transforms Banff into a snowy wonderland with three ski areas: Sunshine Village, Lake Louise Ski Resort, and Mount Norquay. December through February brings reliable snow and temperatures around 15°F, perfect for skiing but brutal for sightseeing. March offers spring skiing with longer days. Avoid April and May – it's mud season with unpredictable weather and many mountain roads still closed.
