Rain and snow in Cooper
Cooper gets 37 inches of rain and melted snow a year. May is the wettest month and February the driest. Rain or snow falls on about 138 days a year. Snow covers the ground about 62 days of the year.
About 172 frost-free days a year
In half of years the last 32° night comes by April 28 and the first one by October 18. That leaves about 172 frost-free days for gardens, shorter than 58% of U.S. towns.
Heating and cooling a home in Cooper
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Cooper, 90% of that work is heating and 10% 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.
