“Wet days” have at least 0.01" of rain or melted snow. “Snow on ground” counts days with 1" or more. The 30-year range is the coldest and warmest that month’s average temperature got between 1991 and 2020.
Rain and snow in Rocky Mount
Rocky Mount gets 47 inches of rain and melted snow a year. September is the wettest month and February the driest. Rain or snow falls on about 126 days a year. Snow covers the ground about 10 days of the year.
About 188 frost-free days a year
In half of years the last 32° night comes by April 20 and the first one by October 25. That leaves about 188 frost-free days for gardens, longer than 62% of U.S. towns.
Heating and cooling a home in Rocky Mount
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Rocky Mount, 80% of that work is heating and 20% 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.
