About 210 frost-free days a year

Heating and cooling a home in Green Forest
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Green Forest, 72% of that work is heating and 28% is cooling.
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 Green Forest itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Harrison, AR (20 mi, snow) and Harrison Boone Co Airport, AR (16 mi, frost, heat and degree days).
