What December feels like
December is the dampest, dimmest stretch Boise gets, and the valley haze is often at its thickest right through the holidays. The upside is a ski hill you can see from downtown — watching the lit runs from the Greenbelt after dark never stops being a strange and excellent thing.
Winter is doing its thing: 5.6 in of snow in a typical December, with fresh snow on about 6 days. Nearly every night dips below freezing.
