“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 Blue Creek
Blue Creek gets 40 inches of rain and melted snow a year. May is the wettest month and February the driest. Rain or snow falls on about 121 days a year. Snow covers the ground about 35 days of the year.
About 181 frost-free days a year
In half of years the last 32° night comes by April 23 and the first one by October 22. That leaves about 181 frost-free days for gardens, longer than 54% of U.S. towns.
Heating and cooling a home in Blue Creek
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Blue Creek, 87% of that work is heating and 13% 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.
