“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 Turtle Lake
Turtle Lake gets 27 inches of rain and melted snow a year. June is the wettest month and February the driest. Rain or snow falls on about 103 days a year. Snow covers the ground about 131 days of the year.
About 155 frost-free days a year
In half of years the last 32° night comes by May 4 and the first one by October 7. That leaves about 155 frost-free days for gardens, shorter than 76% of U.S. towns.
Heating and cooling a home in Turtle Lake
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Turtle Lake, 96% of that work is heating and 4% 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.
