Page "Concord, New Hampshire" Paragraph 20

Concord, as with much of New England, is within the humid continental climate zone ( Köppen Dfb ), with long, cold, snowy winters, very warm ( and at times humid ) summers, and relatively brief autumns and springs.

In winter, successive storms deliver light to moderate snowfall amounts, contributing to the relatively reliable snow cover.

The dampness is compounded by frequent ( occurring 20 times per year ) plunges to at night, though thaws are frequent, with a few days per winter above.

Summer can bring stretches of humid conditions as well as thunderstorms, but rarely extended periods of or above, with 11 days breaching that mark.

Freezes begin early ( late September ) and cease late ( late May ) in the season, and even summer nights are crisp.
