“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 Mars Hill
Mars Hill gets 45 inches of rain and melted snow a year. July is the wettest month and October the driest. Rain or snow falls on about 143 days a year. Snow covers the ground about 13 days of the year.
About 173 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 173 frost-free days for gardens, shorter than 57% of U.S. towns.
Heating and cooling a home in Mars Hill
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Mars Hill, 86% of that work is heating and 14% 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.
