About 139 frost-free days a year

Heating and cooling a home in Eastman
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Eastman, 96% of that work is heating and 4% 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.

Temperatures and rainfall come from NOAA’s gridded climate normals for Eastman itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Courtenay 1 Nw, ND (9 mi, snow) and Mc Henry 3w, ND (16 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.
