What December feels like
December is likelier to hand you cold rain than a postcard snowfall; the dependable snow waits for the new year. The tree on the Common arrives from Nova Scotia early in the month, an annual thank-you a century old now, and Newbury Street stays walkable if you dress for wind rather than for photographs.
Winter is doing its thing: 9.0 in of snow in a typical December, with fresh snow on about 4 days. about 20 nights dip below freezing.
