Which CAF base has the most "challenging" micro-climate for operations?

From a meteorological standpoint, which base do you believe has the most erratic weather for daily tasks? We frequently hear about the wind in Shearwater or the cold in Wainwright. Anyone who has experienced the "Gander fog," the sudden prairie storms in Shilo, or the humidity surges in Petawawa would be interested in speaking with me. How much of your training pace is actually determined by the local weather as opposed to what the "books" say?
