Winter is Coming

We’re currently in the midst of the first significant cold snap of the season.

Tonight, we’re expecting temperatures to fall to around 20°F on Mount Washington, possibly even dipping into the upper teens. These will be the coldest temperatures experienced on the summit since May 17^th—131 days ago—when we hit a daily minimum of 18°F. And yes, a chance of a light snow shower does exist, although it is a remote possibility.

 The staff’s guesses for our coldest temperature with this cold snap.

Our descent into the winter season usually does kick off in September, which on average harbors the first measurable snowfall of the season. Our average temperature for the month sinks to 41.6°F.

October is (arguably) considered the first month of winter on Mount Washington’s summit, though, with an average monthly temperature that sinks below freezing to 30.2°F, and an average monthly snowfall total of 17.6.”

October is typically the month in which the Sherman Adams State Park building closes up, the Auto Road usually closes to the summit, and we pack up shop down in our summit museum and gift shop. Additionally, preparations for the Snow Cat are in full swing, and wrap up sometime in late October as we prepare for the decidedly more eventful winter work commute.

 First shovel-able snow of the season last year on October 18th, 2015.
