Why visit Banff during Jan–Mar, Jun–Sep?
The main season with the warmest weather, longest days, and all trails accessible by mid-July. July-August are the busiest months.

Low season (Nov) is when prices fall hardest. Expect weather extremes (heat, humidity, cold, or rain depending on the destination) and reduced hours at some seasonal businesses, but the trade-off can be worth it if budget or solitude matters more than perfect conditions.
