Rain and snow in Germantown
Germantown gets 47 inches of rain and melted snow a year. May is the wettest month and November the driest. Rain or snow falls on about 136 days a year. Snow covers the ground about 15 days of the year.
About 195 frost-free days a year

Heating and cooling a home in Germantown
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Germantown, 81% of that work is heating and 19% 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.
