Rain and snow in Logan
Logan gets 41 inches of rain and melted snow a year. September is the wettest month and February the driest. Rain or snow falls on about 134 days a year. Snow covers the ground about 46 days of the year.
About 194 frost-free days a year

Heating and cooling a home in Logan
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Logan, 87% of that work is heating and 13% 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.
