Mount Washington in Winter
My brother actually backpacked in the middle of winter, including sleeping out in a tent overnight.
He and some friends once backpacked up Mount Washington in February,
spending the night in a tent, above timberline, with temperatures well below zero.
The next morning they backpacked on to the summit, where the wind was blowing so hard
that they could barely stay on their feet. He said that it actually sounded like a jet engine.
They later found out that at the time they were crossing the summit of Mount Washington,
the average wind speed was about 90mph, gusting to 110, and the temperature near 30 below.
He said that they were dressed more like astronauts than hikers, but it was still a wee bit chilly!

From the Mount Washington Observatory website:
"Home of the World's Worst Weather"
Mount Washington presents the most severe combinations of wind, cold, icing and
storminess available anywhere in the world where people are on hand to take measurements.
The summit lies in the path of the principal storm tracks and air mass routes affecting the northeastern United States,
and it is, because of its elevation, biologically and ecologically similar to the subarctic zone.
