Rain and snow in Coleman
Coleman gets 31 inches of rain and melted snow a year. May is the wettest month and January the driest. Rain or snow falls on about 77 days a year.
About 171 frost-free days a year

Heating and cooling a home in Coleman
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Coleman, 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.
