A common springtime visitor, the black fly, can be quite prevalent in late spring, especially near water bodies.

Nights often cool down, providing comfortable sleeping conditions. Humidity levels remain moderate. Expect frequent afternoon thunderstorms, especially in July and August. Summer provides ideal conditions for swimming, paddling, and various water activities. Fall (September-October): Temperatures range from the 30s to 60s Fahrenheit (around -1 to 15 degrees Celsius). The air feels crisp and dry. Peak foliage generally occurs from late September to mid-October, drawing many visitors. Early season snow can occur at higher elevations during this period. Winter (November - March): Winter brings cold temperatures, often dropping well below freezing. Expect typical temperatures from 0 to 30s Fahrenheit (-18 to 0 degrees Celsius), with even colder conditions in the higher elevations.
