Data-derived climate profile
How Willsboro's climate pattern fits together
heating led · mid swing
Willsboro's energy balance leans toward cold weather: 7,301 annual heating degree days against 513 for cooling. Its 50.9°F seasonal range still makes the monthly rows more useful than the annual average alone.
Willsboro's frost-free season lasts about 165 days, a middle-length window whose endpoints matter more than the annual average. It describes freeze probability, not year-specific planting conditions.
July and January mark the typical warm and cold ends of the calendar in Willsboro's middle-range seasonal profile. The measured spread is 50.9°F. The annual average is 46°F. Neither the annual mean nor one extreme month represents the full calendar on its own.
A moisture-range label is withheld because Willsboro'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 Willsboro'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 Willsboro, not an official NOAA class or a year-ahead forecast.

Place identity: U.S. Census Bureau 2024 Gazetteer places. The 2024 Census Gazetteer identifies the exact name-and-state match as a census-designated place (GEOID 3682260), not an incorporated municipality. Match rule for Willsboro: exact normalized name + state only, no fuzzy expansion, so nearby differently spelled facilities stay unmatched.
On this page every temperature, precipitation, and derived score for Willsboro comes from its primary NOAA station record.
