“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 Lake Creek
Lake Creek gets 18 inches of rain and melted snow a year. May is the wettest month and January the driest. Rain or snow falls on about 82 days a year. Snow covers the ground about 60 days of the year.
About 132 frost-free days a year
In half of years the last 32° night comes by May 16 and the first one by September 26. That leaves about 132 frost-free days for gardens, shorter than 94% of U.S. towns.
Heating and cooling a home in Lake Creek
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Lake Creek, 91% of that work is heating and 9% 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.
