About 190 frost-free days a year

Heating and cooling a home in Keene
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Keene, 87% of that work is heating and 13% is cooling, so the furnace matters far more than the air conditioner.
Degree days measure how far each day’s average temperature falls below or rises above 65°, added up over a year. Source: NOAA station normals.

Snow, frost dates and day counts come from NOAA’s weather station at Coshocton Wpc Plt, OH (7 mi, snow) and Coshocton Ag Rsch Stn, OH (3 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast. Source: NOAA NCEI U.S. Climate Normals, 1991–2020 and 1901–2000.
