Data-derived climate profile

How Scotts Mills's climate pattern fits together

heating led · low swing

Heating is the larger measured load in Scotts Mills, at 6,067 degree days versus 127 for cooling. Unlike a strongly continental record, however, its 25.4°F month-to-month range is compact; persistent cool-season demand matters more than a dramatic summer-to-winter reversal.

Scotts Mills's frost-free season lasts about 191 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.

Temperature varies within a narrow 25.4°F band across the normal year. August and December mark the typical warm and cold ends of the calendar. The annual average is 49°F. Monthly rows still matter, but they refine a steady profile rather than reveal two climatic extremes.

A moisture-range label is withheld because Scotts Mills's annual precipitation total is unavailable. Monthly source values remain visible where NOAA provides them, and no annual amount is reconstructed from incomplete data.

These labels group NOAA 1991-2020 normals from Scotts Mills's primary station, so the winter figures are a thirty-year average and not a floor: a single hard season can run well below them. Treat each band as a descriptive range for Scotts Mills, not an official NOAA class or a year-ahead forecast.
