Heating and cooling a home in Stanley
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Stanley, 100% of that work is heating and 0% 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 Stanley itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Stanley Rs, ID (3 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast.
