Rain and snow in Notus

About 165 frost-free days a year

Heating and cooling a home in Notus
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Notus, 88% of that work is heating and 12% 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 Notus itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Parma Exp Stn, ID (10 mi) away. Normals are 30-year averages, not a forecast.
