Well if you wanna ski or snowshoe i concur. If you want to get up top, summer is the time to do it. With the wind it was a bit uncomfortable even yesterday. It's pretty spectacular though. Yesterday would have been a super high visibility day but the haziness was attributed to smoke from wildfires in Canada. Obviously the weather is typically brutal in winter at the summit, and auto road is closed. I guess the cog still runs unless the winds are blowing 100 mph or something. BTW, still some decent 'snow' in spots on the north face of Mt Washington, as well as a few places on other peaks on the Presidential range.
