When you tell someone you are a pilot and live in a state that has predominantly IFR conditions November through March, they inevitably make a reference to all flight training ceasing in the winter because of the weather. And there is some truth to this, as I learned as a student pilot in the Pacific Northwest.
Seattle leads the nation in cloudy and foggy days, according to weather statistics gathered by Currentresults.com, coming in with 226 cloudy and 165 foggy days per year, followed closely by Portland, Oregon, with 165 cloudy and 125 foggy. Combine a low ceiling with a low freezing level, and you will find a great many general aviation pilots opt to stay on the ground, planning to fly on a better weather day.
