Rain and snow in Kelly
Kelly gets 32 inches of rain and melted snow a year. July is the wettest month and February the driest. Rain or snow falls on about 112 days a year.
About 133 frost-free days a year
In half of years the last 32° night comes by May 20 and the first one by October 2. That leaves about 133 frost-free days for gardens, shorter than 93% of U.S. towns.
Heating and cooling a home in Kelly
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Kelly, 97% of that work is heating and 3% 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.
