Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Genesee, 95% of that work is heating and 5% 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 Genesee itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Pullman 2 Nw, WA (19 mi) away. Normals are 30-year averages, not a forecast.
